On Scars

It was slightly surprising - but not altogether unexpected - that on the weekend when my book The Sex Myth has its first excerpt and interview in the Telegraph that "feminists" would immediately take objection. Interestingly though the shape this appears to have followed, rather than an actual criticism of work I have done or books I have written, is a number of nasty "terrible skin" remarks about me from lady columnists who really ought to know better.

It speaks volumes about the preoccupations of critics that when faced with a woman whose attitudes, thought processes, and life experience are almost orthogonal to their own their first response is to criticise her looks. I am not conventionally attractive, but to paraphrase Steve Martin: when presented with all this, that's the best you can come up with?

Last year I wrote a commentary on the ubiquitous blogging that was going on surrounding the bullying of feminist bloggers. As I pointed out then, bullying does not only happen to feminists, and some of the people who were getting group hugs out of being the victims of trolling have themselves trolled other people. (Top tip: just because you write above the line doesn't make you not a troll. @'ing someone in to your insults of them on Twitter? Does.)

So to make explicit in case it was not clear: I will never ridicule someone I disagree with because of their looks. If you can't craft a sensible argument against someone's thoughts and actions and have to go for the low-hanging fruit instead, you have failed at rational discourse. And arguably also failed at feminism.

I wrote previously about the experience of having facial scars on my original blog but have since taken that content down. However Emily Hornaday archived it and so I reprint it here. If you are someone who is going through a rough time confidence-wise, please know that while haters never, ever change, how you feel about yourself will. It really does get better. (Update: I have also written about this theme for Guardian Weekend magazine.)

mercredi, janvier 13

Let me tell you about the best gift I ever received. And it's not a bit of sparkly jewellery, or a shiny car, or even a thoughtful trinket of affection.

I'm talking about my scars.

I had terrible acne as a teenager. By the age of 16 it was so bad a dermatologist said it was the worst she'd ever seen, which, ya know, is not super encouraging. At the hospital where I volunteered mothers pulled their children away from me, convinced I was plagued with something contagious. Strangers avoided making eye contact.

It was so bad I could not wash my face without bleeding. Many mornings I woke up stuck to the pillowcase. And oh yeah, it was only on my face. Not one blemish anywhere else on my body. To this day, I still never have seen a photo of anything like it - apart from some daguerrotypes of smallpox patients.

It was a very long, and very expensive, journey to improving my skin - remember, this all went down in America where having a disfiguring condition you have no control over is not covered by health insurance, and duh, there's no NHS.

Long story short a lot of Roaccutane and Dianette did for the acne. And more importantly here's what I learned:

1. Beauty is fleeting. Thank fuck for that.

I had a narrow escape from being just another boring blonde - not to mention an early release from the cycle of self-hatred and frantic desperation that plagues many women as they age. Corollary 1a: The larger part of how people perceive you is how you present yourself.

2. People can be hurtful to strangers. That's their problem.

My best childhood mate had spina bifida. She walked on sticks and refused to use a wheelchair for reasons I only started to appreciate years later. Looking like a medical oddity gave me, for a very brief time, a very small taste of what she encounters every day of her life. It made me pity people who equate someone's appearance with their value as a person. This generalises magnificently to strangers judging you for, in fact, anything at all. Corollary 2a: The most vocal critics are often the most insecure.

3. Other people have things you don't. Big deal.

There is no such thing as the Most Beautiful Woman in the World (sorry Buttercup). Who cares? What is considered desirable is not especially worth getting hung up on. You may not be a six-foot Amazon so will never have legs up to your neck - but for all you know, that same supermodel would give her left arm to have your hair. This concept generalises to wealth, success, talent, and intelligence as well. Corollary 3a: Envy of other women's looks is a zero-sum game, and uses far too much time and energy to be bothered with.

4. Quality of love is not a function of attractiveness.

Elizabeth Taylor, for instance, has been married eight times. Beautiful people have dry spells and get their hearts broken like everyone else. The most worthwhile and loving relationships in my life all happened after my skin problems. And for what it's worth, I've been fortunate to date some pretty nice, smart (and attractive) men in my time. See Corollary 1a above.

5. Confidence doesn't come overnight.

It also doesn't happen in a vacuum; it requires nurturing. As with anything else worth having it's work. But let me tell you, it is so worth the work. A mate recently told me about a magazine 'happiness quiz' in which one of the questions was, "are you comfortable with your body, and do you exercise regularly?" If you can see why this should not have been a single question, you're on the way. Corollary 5a: Confidence happens when you let it happen. No one gives it to you, which is great, because it also means they can't take it from you.

6. When someone says I am beautiful, they really, really mean it.

There is something about knowing someone sees you, quirks and all, and likes what they see... something rare and kind of overwhelming (in a good way). 'Beautiful' is one of those words (a bit like 'awesome') that has lost meaning in being overused as a generic affirmative. We call all sorts of people beautiful in one sentence and tear them down in the next. I'm happy to be different enough that anyone who uses it to describe me sees more than just hair and makeup.

LaSca: a Large Scale Group Decision Support System

Decision-making involves choosing between one ore more alternatives, to achieve one or more goals. To support this process, there are decision support systems that employ different approaches, supporting groups or not. Generally, however, these systems do not have great flexibility; their users have to follow preestablished decision methods. This paper, after exposing some decision-making processes, describes a system, LaSca (from Large Scale), to support decisions in large-scale groups. This system, besides allowing effective achievement of the benefits of deciding in large groups through the proper structuring of the group, also allows its users to define themselves how this structuring will happen, based or not in the existing theories on the subject. So, in addition to facilitate the decision-making process, LaSca also allows its users to decide how to decide.

An efficient edge swap mechanism for enhancement of robustness in scale-free networks in healthcare systems

This paper presents a sequential edge swap (SQES) mechanism to design a robust network for a healthcare system utilising energy and communication range of nodes. Two operations: sequential degree difference operation (SQDDO) and sequential angle sum operation (SQASO) are performed to enhance the robustness of network. With equivalent degrees of nodes from the network's centre to its periphery, these operations build a robust network structure. Disaster attacks that have a substantial impact on the network are carried out using the network information. To identify a link between the malicious and disaster attacks, the Pearson coefficient is employed. SQES creates a robust network structure as a single objective optimisation solution by changing the connections of nodes based on the positive correlation of these attacks. SQES beats the current methods, according to simulation results. When compared to hill-climbing algorithm, simulated annealing, and ROSE, respectively, the robustness of SQES is improved by roughly 26%, 19% and 12%.

Elon Musk se défend au tribunal d'accusations "scandaleuses" sur des tweets de 2018

Elon Musk a tenté de montrer lundi au tribunal que ses fameux tweets de 2018, sur sa volonté de sortir Tesla de la Bourse, n'avaient rien de trompeurs ou de frauduleux, contrairement aux accusations d'investisseurs qui disent avoir perdu des millions de dollars à cause du milliardaire.

Le patron de Tesla -- et de Twitter, depuis fin octobre -- a assuré qu'il n'avait "jamais" cherché à tromper les investisseurs, et que l'accusation de fraude était "scandaleuse".

Il avait créé la stupeur le 7 août 2018 en affirmant qu'il voulait retirer son groupe automobile de la Bourse au prix de 420 dollars par action, puis en assurant que le financement était "sécurisé".

"Je ne disais pas que c'était fait, je disais simplement que je l'envisageais, que j'y pensais. Et qu'à mon avis le financement était sécurisé", a déclaré Elon Musk à la barre, dans le tribunal de San Francisco où a lieu le procès.

La semaine dernière, le principal avocat des plaignants, Nicholas Porritt, avait accusé le dirigeant d'avoir "menti" et d'être responsable des pertes des investisseurs.

Le titre avait bondi dans la foulée des tweets très inhabituels (et le Nasdaq avait temporairement suspendu le cours de l'action Tesla), avant de décliner les jours suivants. Des articles de presse avaient fini par révéler que le patron n'avait pas vraiment les fonds.

Tesla était restée cotée en Bourse.

A travers ses questions, Nicholas Porritt a cherché à montrer qu'Elon Musk n'avait pas réalisé les consultations appropriées, et ne disposait pas ni des éléments nécessaires, ni de l'autorité pour faire une annonce aussi fracassante, surtout sur Twitter, et surtout pendant que les marchés étaient ouverts.

- "M. Tweet" -

L'avocat a mis en avant des échanges acerbes le 12 août 2018 entre le milliardaire et Yasir Al-Rumayyan, le directeur du fonds souverain saoudien, qui s'était engagé "catégoriquement" et "sans hésitation" à financer l'opération, selon Elon Musk.

"Le financement n'était pas vraiment sécurisé, n'est-ce pas?", a demandé M Porritt.

Yasir Al-Rumayyan a fait du "rétropédalage", a rétorqué le patron de Tesla.

Il a assuré qu'il avait de toute façon la possibilité de vendre ses actions de son autre fleuron, SpaceX, "l'entreprise non cotée la plus valorisée des Etats-Unis".

"Cela m'aurait brisé le cœur (de les vendre), mais je l'aurais fait si besoin", a-t-il déclaré, évoquant comment il avait dû se séparer d'actions de Tesla pour racheter Twitter l'année dernière.

Costume sombre, chemise blanche et cravate, il est apparu hésitant, ne se souvenant pas de nombreux emails et détails, et répondant souvent à côté des questions pour répéter à l'envie les messages qu'il voulait faire passer au jury.

Au point de faire perdre patience à l'avocat des investisseurs. "Nous avons passé toute une journée ensemble à Austin, vous vous en souvenez M. Tweet?!", a lancé Nicholas Porritt, avant de corriger pour "M. Musk".

- "Karma" -

L'accusation est aussi revenue sur le prix proposé par Elon Musk, 420 dollars par action. Aux Etats-Unis, les chiffres 4 et 20 accolés sont associés à la consommation de cannabis. Quand le milliardaire a proposé de racheter Twitter au printemps dernier, il a choisi un prix de 54,20 dollars par action.

"Avez-vous arrondi à 420 en guise de blague à l'attention de votre petite amie?", a demandé Nicholas Porritt.

"Ce n'était pas une blague, cela représentait une prime de 20% au-dessus du prix de l'action", a répondu Elon Musk, reconnaissant cependant qu'il y a "un certain karma autour de 420".

"Pas sûr que ce soit un bon ou un mauvais karma à ce stade", a-t-il encore plaisanté.

Son avocat Alex Spiro l'a ensuite aidé à dresser le portrait d'un immigré parti de rien, venu aux Etats-Unis - "là où les grandes choses sont possibles" - après une enfance "malheureuse" en Afrique du Sud, selon les mots du milliardaire.

"On m'a traité de fou à de nombreuses reprises", a déclaré Elon Musk après avoir énuméré les entreprises qu'il a cofondées.

Mais "à ce stade je crois que j'ai levé plus d'argent que quiconque dans l'histoire", s'est-il vanté, attribuant sa réussite à son "honnêteté" à l'égard des investisseurs.

Le procès doit durer trois semaines. Dans une précédente décision liée à cette affaire, un juge avait estimé que le fameux tweet de 2018 pouvait être considéré comme "faux et trompeur".

Le gendarme boursier américain, la SEC, avait de son côté obligé Elon Musk à céder la présidence du conseil d'administration, à payer une amende et à faire pré-approuver par un juriste ses tweets directement liés à l'activité de Tesla.

An intelligent approach to classify and detection of image forgery attack (scaling and cropping) using transfer learning

Image forgery detection techniques refer to the process of detecting manipulated or altered images, which can be used for various purposes, including malicious intent or misinformation. Image forgery detection is a crucial task in digital image forensics, where researchers have developed various techniques to detect image forgery. These techniques can be broadly categorised into active, passive, machine learning-based and hybrid. Active approaches involve embedding digital watermarks or signatures into the image during the creation process, which can later be used to detect any tampering. On the other hand, passive approaches rely on analysing the statistical properties of the image to detect any inconsistencies or irregularities that may indicate forgery. In this paper for the detection of scaling and cropping attack a deep learning method has been proposed using ResNet. The proposed method (Res-Net-Adam-Adam) is able to achieve highest amount of accuracy of 99.14% (0.9914) while detecting fake and real images.

Impact of servicescape dimensions on customer satisfaction and behavioural intentions: a case of casual dining restaurants

Physical and social aspects each make up a separate part of servicescape. Together, these make up the servicescape. Although previous research has frequently investigated these aspects separately, the purpose of this study is to simultaneously find out the impact of both aspects within the casual dining restaurants' context. In total, 462 customers in Delhi were polled for this study, and structural equation modelling was used to analyse the data. According to the results, both the social and physical parts of the servicescape have the ability to affect how satisfied customers are, which in turn can affect how they behave in the future.

Innovative Pedagogical Strategies of Streaming, Just-in-Time Teaching, and Scaffolding: A Case Study of Using Videos to Add Business Analytics Instruction Across a Curriculum

Aim/Purpose: Business analytics is a cross-functional field that is important to implement for a college and has emerged as a critically important core component of the business curriculum. It is a difficult task due to scheduling concerns and limits to faculty and student resources. This paper describes the process of creating a central video repository to serve as a platform for just in time teaching and the impact on student learning outcomes. Background: Industry demand for employees with analytical knowledge, skills, and abilities requires additional analytical content throughout the college of business curriculum. This demand needs other content to be added to ensure that students have the prerequisite skills to complete assignments. Two pedagogical approaches to address this issue are Just-in-Time Teaching (JiTT) and scaffolding, grounded in the Vygoskian concept of “Zone of Proximal Development. Methodology: This paper presents a case study that applies scaffolding and JiTT teaching to create a video repository to add business analytics instruction to a curriculum. The California Critical Thinking Skills Test (CCTST) and Major Field Test (MFT) scores were analyzed to assess learning outcomes. Student and faculty comments were considered to inform the results of the review. Contribution: This paper demonstrates a practical application of scaffolding and JiTT theory by outlining the process of using a video library to provide valuable instructional resources that support meaningful learning, promote student academic achievement, and improve program flexibility. Findings: A centrally created library is a simple and inexpensive way to provide business analytics course content, augmenting standard content delivery. Assessment of learning scores showed an improvement, and a summary of lessons learned is provided to guide implications. Recommendations for Practitioners: Pedagogical implications of this research include the observation that producing a central library of instructor created videos and assignments can help address knowledge and skills gaps, augment the learning of business analytics content, and provide a valuable educational resource throughout the college of business curriculum. Recommendation for Researchers: This paper examines the use of scaffolding and JiTT theories. Additional examination of these theories may improve the understanding and limits of these concepts as higher education evolves due to the combination of market forces changing the execution of course delivery. Impact on Society: Universities are tasked with providing new and increasing skills to students while controlling the costs. A centrally created library of instructional videos provides a means of delivering meaningful content while controlling costs. Future Research: Future research may examine student success, including the immediate impact of videos and longitudinally using video repositories throughout the curriculum. Studies examining the approach across multiple institutions may help to evaluate the success of video repositories. Faculty acceptance of centrally created video libraries and assignments should be considered for the value of faculty recruiting and use in the classroom. The economic impact on both the university and students should be evaluated.

Development and validation of scale to measure minimalism - a study analysing psychometric assessment of minimalistic behaviour! Consumer perspective

This research aims to establish a valid and accurate measurement scale and identify consumer-driven characteristics for minimalism. The study has employed a hybrid approach to produce items for minimalism. Expert interviews were conducted to identify the items for minimalism in the first phase followed by consumer survey to obtain their response in second phase. A five-point Likert scale was used to collect the data. Further, data was subjected to reliability and validity check. Structural equation modelling was used to test the model. The findings demonstrated that there are five dimensions by which consumers perceive minimalism: decluttering, mindful consumption, aesthetic choices, financial freedom, and sustainable lifestyle. The outcome also revealed a high correlation between simplicity and well-being. This study is the first to provide a reliable and valid instrument for minimalism. The results will have several theoretical and practical ramifications for society and policymakers. It will support policymakers in gauging and encouraging minimalistic practices, which enhance environmental performance and lower carbon footprint.

Advancing mobile open learning through DigiBot technology: a case study of using WhatsApp as a scalable learning tool

This article presents a case study that outlines the potential of DigiBot technology, an interactive automated response program, in mobile open learning (MOL) for business subjects. The study, which draws on a project implemented in Sub-Saharan Africa, demonstrates the applications of DigiBots delivered via WhatsApp to over 650,000 learners. Employing a mixed-methods approach, the article reports on live event tracking, qualitative observations from facilitators and learning technologists, and a learner survey (<i>N</i> = 304,000). The research offers practical recommendations and proposes a model for scalable DigiBot learning. Findings reveal that in this case, DigiBot MOL had the potential to effectively address two key obstacles in open learning: accessibility and scalability. Leveraging mobile platforms such as WhatsApp mitigates accessibility restrictions, particularly in resource-constrained contexts, while tailored micro-learning enhances scalability.

DAR: A Modern Institutional Repository with a Scalability Twist

The Digital Assets Repository (DAR) is an Institutional Repository developed at the Bibliotheca Alexandrina to manage the full lifecycle of a digital asset: its creation and ingestion, its metadata management, storage and archival in addition to the necessary mechanisms for publishing and dissemination. DAR was designed with a focus on integrating DAR with different sources of digital objects and metadata in addition to integration with applications built on top of the repository. As a modern repository, the system architecture demonstrates a modular design relying on components that are best of the breed, a flexible content model for digital objects based on current standards and heavily relying on RDF triples to define relations. In this paper we will demonstrate the building blocks of DAR as an example of a modern repository, discussing how the system addresses the challenges that face an institution in consolidating its assets and a focus on solving scalability issues.

Digital Literacy in the Core: The Emerging Higher Education Landscape

Aim/Purpose: Digital literacy is critical to participation in a contemporary knowledge-based society and is requisite to both academic success and career development. Institutions of higher education have been slow to define, assess, and amplify digital literacy in parallel with advances in the enhancement of reading, writing, and arithmetic literacy. Perhaps as a consequence of the pandemic, awareness appears to be growing of the need to infuse digital literacy at both institutional and individual levels. The purpose of this paper is to investigate the promotion and amplification of digital literacy within top universities around the globe. Background: For years, the role of higher education in the amplification of digital literacy among college students has been debated, but efforts have been limited primarily to ad hoc, unsystematic attempts to rectify disparities between students’ exposure and understanding. The impacts of COVID-19 exposed the reality that many institutions, professors, and college students were under-prepared for the surge in reliance on digital technologies. Methodology: This paper explores the prevalence of digital literacy in the top public and private universities around the globe by conducting a qualitative examination on compulsory requirements, digital literacy offerings, university identified digital literacy initiatives, and university strategic plans. Contribution: This paper contributes to the body of knowledge by providing evidence for the need to expand the constructs of what it means to be digitally literate to address the ever-expanding range of emerging technologies and the impact of those technologies on society. Findings: The review of digital literacy amplification at top universities showed that none of the universities' admissions requirements required students to demonstrate digital competence and compulsory digital literacy was uncommon. However, a majority of universities undertook some form of initiative to promote digital literacy. These initiates included a focus on developing digitally literate society and workforce or developing innovative approaches to digital literacy education. Recommendations for Practitioners: The pandemic has generated a greater sense of urgency for institutions of higher education to ensure access to and understanding of digital technologies by students, faculty, and staff. Educational institutions will have to adapt their methodologies to promote explicit and intentionally reasoned digital literacy strategies that combine the competencies possessed by users of technology with the generation of new competencies required to successfully participate in the digital transformation of education, business, and society. Recommendations for Researchers: This paper examined the top 50 universities around the globe. Additional re-search is needed to examine national, regional and local efforts in the quest to address the need for a digitally literate citizenry. Impact on Society: COVID-19 has thrust us into a new normal wherein digital competence is foundational to success in an ever digitally reliant world. Institutions of higher education are best positioned to carry out the initiatives, programs and re-search needed to enhance the digital literacy of all citizens, not just students and employees. Future Research: Societal impacts of the COVID-19 pandemic continue to emerge and will resonate for decades to come. Continued investigation, exploration and dis-semination of information related to effort to enhance and amplify digital literacy is necessary to ensure momentum to reimagine digital literacy education is maintained.

HUNT: Scavenger Hunt with Augmented Reality

This project shows a creative approach to the familiar scavenger hunt game. It involved the implementation of an iPhone application, HUNT, with Augmented Reality (AR) capability for the users to play the game as well as an administrative website that game organizers can use to create and make available games for users to play. Using the HUNT mobile app, users will first make a selection from a list of games, and they will then be shown a list of objects that they must seek. Once the user finds a correct object and scans it with the built-in camera on the smartphone, the application will attempt to verify if it is the correct object and then display associated multi-media AR content that may include images and videos overlaid on top of real world views. HUNT not only provides entertaining activities within an environment that players can explore, but the AR contents can serve as an educational tool. The project is designed to increase user involvement by using a familiar and enjoyable game as a basis and adding an educational dimension by incorporating AR technology and engaging and interactive multimedia to provide users with facts about the objects that they have located

Analysis of the Scale Types and Measurement Units in Enterprise Architecture (EA) Measurement

Aim/Purpose: This study identifies the scale types and measurement units used in the measurement of enterprise architecture (EA) and analyzes the admissibility of the mathematical operations used. Background: The majority of measurement solutions proposed in the EA literature are based on researchers’ opinions and many with limited empirical validation and weak metrological properties. This means that the results generated by these solutions may not be reliable, trustworthy, or comparable, and may even lead to wrong investment decisions. While the literature proposes a number of EA measurement solutions, the designs of the mathematical operations used to measure EA have not yet been independently analyzed. It is imperative that the EA community works towards developing robust, reliable, and widely accepted measurement solutions. Only then can senior management make informed decisions about the allocation of resources for EA initiatives and ensure that their investment yields optimal results. Methodology: In previous research, we identified, through a systematic literature review, the EA measurement solutions proposed in the literature and classified them by EA entity types. In a subsequent study, we evaluated their metrology coverage from both a theoretical and empirical perspective. The metrology coverage was designed using a combination of the evaluation theory, best practices from the software measurement literature including the measurement context model, and representational theory of measurement to evaluate whether EA measurement solutions satisfy the metrology criteria. The research study reported here presents a more in-depth analysis of the mathematical operations within the proposed EA measurement solutions, and for each EA entity type, each mathematical operation used to measure EA was examined in terms of the scale types and measurement units of the inputs, their transformations through mathematical operations, the impact in terms of scale types, and measurement units of the proposed outputs. Contribution: This study adds to the body of knowledge on EA measurement by offering a metrology-based approach to analyze and design better EA measurement solutions that satisfy the validity of scale type transformations in mathematical operations and the use of explicit measurement units to allow measurement consistency for their usage in decision-making models. Findings: The findings from this study reveal that some important metrology and quantification issues have been overlooked in the design of EA measurement solutions proposed in the literature: a number of proposed EA mathematical operations produce numbers with unknown units and scale types, often the result of an aggregation of undetermined assumptions rather than explicit quantitative knowledge. The significance of such aggregation is uncertain, leading to numbers that have suffered information loss and lack clear meaning. It is also unclear if it is appropriate to add or multiply these numbers together. Such EA numbers are deemed to have low metrological quality and could potentially lead to incorrect decisions with serious and costly consequences. Recommendations for Practitioners: The results of the study provide valuable insights for professionals in the field of EA. Identifying the metrology limitations and weaknesses of existing EA measurement solutions may indicate, for instance, that practitioners should wait before using them until their design has been strengthened. In addition, practitioners can make informed choices and select solutions with a more robust metrology design. This, in turn, will benefit enterprise architects, software engineers, and other EA professionals in decision making, by enabling them to take into consideration factors more adequately such as cost, quality, risk, and value when assessing EA features. The study’s findings thus contribute to the development of more reliable and effective EA measurement solutions. Recommendation for Researchers: Researchers can use with greater confidence the EA measurement solutions with admissible mathematical operations and measurement units to develop new decision-making models. Other researchers can carry on research to address the weaknesses identified in this study and propose improved ones. Impact on Society: Developers, architects, and managers may be making inappropriate decisions based on seriously flawed EA measurement solutions proposed in the literature and providing undue confidence and a waste of resources when based on bad measurement design. Better quantitative tools will ultimately lead to better decision making in the EA domain, as in domains with a long history of rigor in the design of the measurement tools. Such advancements will benefit enterprise architects, software engineers, and other practitioners, by providing them with more meaningful measurements for informed decision making. Future Research: While the analysis described in this study has been explicitly applied to evaluating EA measurement solutions, researchers and practitioners in other domains can also examine measurement solutions proposed in their respective domains and design new ones.

Map reduce-based scalable Lempel-Ziv and application in route prediction

Prediction of route based on historical trip observation of users is widely employed in location-based services. This work concentrates on building a route prediction system using Lempel-Ziv technique applied to a historical corpus of user travel data. Huge continuous logs of historical GPS traces representing the user's location in past are decomposed into smaller logical units known as trips. User trips are converted into sequences of road network edges using a process known as map matching. Lempel-Ziv is applied on road network edges to build the prediction model that captures the user's travel pattern in the past. A two-phased model is proposed using a map reduce framework without losing accuracy and efficiency. Model is then used to predict the user's end-to-end route given a partial route travelled by the user at any point in time. The objective of the proposed work is to build a Route Prediction system in which model building and prediction both are horizontally scalable.
