(United States Ninth Circuit) - In a copyright dispute arising out of photographs posted online on defendant's social media website, the district court's summary judgment that defendant was entitled protected by the safe harbor of the Digital Millennium Copyright Act is reversed where: 1) the safe harbor set forth in 17 U.S.C. section 512(c) would apply if the photographs were posted at the direction of users; 2) defendant posted the photographs after a team of volunteer moderators, led by an employee of the defendant, reviewed and approved them; 3) the common law of agency applied to the defendant's safe harbor defense; and 4) there were genuine factual disputes regarding whether the moderators were the defendant's agents.

We consider the skill rating problem for multiplayer games, that is how to infer player skills from game outcomes in multiplayer games. We formulate the problem as a minimization problem $arg min_{s} s^T Delta s$ where $Delta$ is a positive semidefinite matrix and $s$ a real-valued function, of which some entries are the skill values to be inferred and other entries are constrained by the game outcomes. We leverage graph-based semi-supervised learning (SSL) algorithms for this problem. We apply our algorithms on several data sets of multiplayer games and obtain very promising results compared to Elo Duelling (see Elo, 1978) and TrueSkill (see Herbrich et al., 2006).. As we leverage graph-based SSL algorithms and because games can be seen as relations between sets of players, we then generalize the approach. For this aim, we introduce a new finite model, called hypernode graph, defined to be a set of weighted binary relations between sets of nodes. We define Laplacians of hypernode graphs. Then, we show that the skill rating problem for multiplayer games can be formulated as $arg min_{s} s^T Delta s$ where $Delta$ is the Laplacian of a hypernode graph constructed from a set of games. From a fundamental perspective, we show that hypernode graph Laplacians are symmetric positive semidefinite matrices with constant functions in their null space. We show that problems on hypernode graphs can not be solved with graph constructions and graph kernels. We relate hypernode graphs to signed graphs showing that positive relations between groups can lead to negative relations between individuals.

Graphs arise naturally in many real-world applications including social networks, recommender systems, ontologies, biology, and computational finance. Traditionally, machine learning models for graphs have been mostly designed for static graphs. However, many applications involve evolving graphs. This introduces important challenges for learning and inference since nodes, attributes, and edges change over time. In this survey, we review the recent advances in representation learning for dynamic graphs, including dynamic knowledge graphs. We describe existing models from an encoder-decoder perspective, categorize these encoders and decoders based on the techniques they employ, and analyze the approaches in each category. We also review several prominent applications and widely used datasets and highlight directions for future research.

Abstract:
We consider a random object that is associated with both random walks and random media, specifically, the superposition of a configuration of subcritical Bernoulli percolation on an infinite connected graph and the trace of the simple random walk on the same graph. We investigate asymptotics for the number of vertices of the enlargement of the trace of the walk until a fixed time, when the time tends to infinity. This process is more highly self-interacting than the range of random walk, which yields difficulties. We show a law of large numbers on vertex-transitive transient graphs. We compare the process on a vertex-transitive graph with the process on a finitely modified graph of the original vertex-transitive graph and show their behaviors are similar. We show that the process fluctuates almost surely on a certain non-vertex-transitive graph. On the two-dimensional integer lattice, by investigating the size of the boundary of the trace, we give an estimate for variances of the process implying a law of large numbers. We give an example of a graph with unbounded degrees on which the process behaves in a singular manner. As by-products, some results for the range and the boundary, which will be of independent interest, are obtained.

Abstract:
Symmetric independence relations are often studied using graphical representations. Ancestral graphs or acyclic directed mixed graphs with $m$-separation provide classes of symmetric graphical independence models that are closed under marginalization. Asymmetric independence relations appear naturally for multivariate stochastic processes, for instance, in terms of local independence. However, no class of graphs representing such asymmetric independence relations, which is also closed under marginalization, has been developed. We develop the theory of directed mixed graphs with $mu $-separation and show that this provides a graphical independence model class which is closed under marginalization and which generalizes previously considered graphical representations of local independence. Several graphs may encode the same set of independence relations and this means that in many cases only an equivalence class of graphs can be identified from observational data. For statistical applications, it is therefore pivotal to characterize graphs that induce the same independence relations. Our main result is that for directed mixed graphs with $mu $-separation each equivalence class contains a maximal element which can be constructed from the independence relations alone. Moreover, we introduce the directed mixed equivalence graph as the maximal graph with dashed and solid edges. This graph encodes all information about the edges that is identifiable from the independence relations, and furthermore it can be computed efficiently from the maximal graph.

Abstract:
Statistical inference for exponential-family models of random graphs with dependent edges is challenging. We stress the importance of additional structure and show that additional structure facilitates statistical inference. A simple example of a random graph with additional structure is a random graph with neighborhoods and local dependence within neighborhoods. We develop the first concentration and consistency results for maximum likelihood and $M$-estimators of a wide range of canonical and curved exponential-family models of random graphs with local dependence. All results are nonasymptotic and applicable to random graphs with finite populations of nodes, although asymptotic consistency results can be obtained as well. In addition, we show that additional structure can facilitate subgraph-to-graph estimation, and present concentration results for subgraph-to-graph estimators. As an application, we consider popular curved exponential-family models of random graphs, with local dependence induced by transitivity and parameter vectors whose dimensions depend on the number of nodes.

Abstract:
Sparse exchangeable graphs on $mathbb{R}_{+}$, and the associated graphex framework for sparse graphs, generalize exchangeable graphs on $mathbb{N}$, and the associated graphon framework for dense graphs. We develop the graphex framework as a tool for statistical network analysis by identifying the sampling scheme that is naturally associated with the models of the framework, formalizing two natural notions of consistent estimation of the parameter (the graphex) underlying these models, and identifying general consistent estimators in each case. The sampling scheme is a modification of independent vertex sampling that throws away vertices that are isolated in the sampled subgraph. The estimators are variants of the empirical graphon estimator, which is known to be a consistent estimator for the distribution of dense exchangeable graphs; both can be understood as graph analogues to the empirical distribution in the i.i.d. sequence setting. Our results may be viewed as a generalization of consistent estimation via the empirical graphon from the dense graph regime to also include sparse graphs.

Abstract:
A signalling pathway is a sequence of chemical reactions initiated by a stimulus which in turn affects a receptor, and then through some intermediate steps cascades down to the final cell response. Based on the technique of flow cytometry, samples of cell-by-cell measurements are collected under each experimental condition, resulting in a collection of interventional data (assuming no latent variables are involved). Usually several external interventions are applied at different points of the pathway, the ultimate aim being the structural recovery of the underlying signalling network which we model as a causal Directed Acyclic Graph (DAG) using intervention calculus. The advantage of using interventional data, rather than purely observational one, is that identifiability of the true data generating DAG is enhanced. More technically a Markov equivalence class of DAGs, whose members are statistically indistinguishable based on observational data alone, can be further decomposed, using additional interventional data, into smaller distinct Interventional Markov equivalence classes. We present a Bayesian methodology for structural learning of Interventional Markov equivalence classes based on observational and interventional samples of multivariate Gaussian observations. Our approach is objective, meaning that it is based on default parameter priors requiring no personal elicitation; some flexibility is however allowed through a tuning parameter which regulates sparsity in the prior on model space. Based on an analytical expression for the marginal likelihood of a given Interventional Essential Graph, and a suitable MCMC scheme, our analysis produces an approximate posterior distribution on the space of Interventional Markov equivalence classes, which can be used to provide uncertainty quantification for features of substantive scientific interest, such as the posterior probability of inclusion of selected edges, or paths.

Abstract:
In this paper, we consider the knot-matching problem arising in computational forestry. The knot-matching problem is an important problem that needs to be solved to advance the state of the art in automatic strength prediction of lumber. We show that this problem can be formulated as a quadripartite matching problem and develop a sequential decision model that admits efficient parameter estimation along with a sequential Monte Carlo sampler on graph matching that can be utilized for rapid sampling of graph matching. We demonstrate the effectiveness of our methods on 30 manually annotated boards and present findings from various simulation studies to provide further evidence supporting the efficacy of our methods.

Abstract:
We present results on the concentration properties of the spectral norm $|A_{p}|$ of the adjacency matrix $A_{p}$ of an Erdős–Rényi random graph $G(n,p)$. First, we consider the Erdős–Rényi random graph process and prove that $|A_{p}|$ is uniformly concentrated over the range $pin[Clog n/n,1]$. The analysis is based on delocalization arguments, uniform laws of large numbers, together with the entropy method to prove concentration inequalities. As an application of our techniques, we prove sharp sub-Gaussian moment inequalities for $|A_{p}|$ for all $pin[clog^{3}n/n,1]$ that improve the general bounds of Alon, Krivelevich, and Vu ( Israel J. Math. 131 (2002) 259–267) and some of the more recent results of Erdős et al. ( Ann. Probab. 41 (2013) 2279–2375). Both results are consistent with the asymptotic result of Füredi and Komlós ( Combinatorica 1 (1981) 233–241) that holds for fixed $p$ as $n oinfty$.

Abstract:
We study the asymptotic behavior of the clique number in rank-1 inhomogeneous random graphs, where edge probabilities between vertices are roughly proportional to the product of their vertex weights. We show that the clique number is concentrated on at most two consecutive integers, for which we provide an expression. Interestingly, the order of the clique number is primarily determined by the overall edge density, with the inhomogeneity only affecting multiplicative constants or adding at most a $log log (n)$ multiplicative factor. For sparse enough graphs the clique number is always bounded and the effect of inhomogeneity completely vanishes.

Infantile hemangiomas have a period of rapid growth in early infancy. Most hemangioma growth is completed by 5 months of age, but the majority of patients are not seen by a specialist until after the growth phase is complete.

The most rapid hemangioma growth is between 1 and 2 months of life, much earlier than previously believed. Patients with high-risk hemangiomas should be followed closely, and treatment initiation should be considered before or during the most rapid growth phase. (Read the full article)

Variation in the emergency department (ED) use of radiographs for asthma, bronchiolitis, and croup exists. Unnecessary radiographs contribute to higher costs of care, decreased ED efficiency, and increased radiation in children.

Despite no changes in guidelines to support routine use, there is a significant upward trend in the use of radiographs for children with emergency department visits for asthma. Pediatric-focused EDs use significantly fewer radiographs for asthma, bronchiolitis, and croup. (Read the full article)

EarLier this week, artist and oral historian Aanchal Malhotra, 28, travelled nearly 240 km to Chandigarh from Delhi, to meet a nonagenarian, who had lived through the Partition of 1947. As she speaks about it now, there's a lump in her throat. "I couldn't sleep that entire night," Malhotra confesses. "Even 70 years on, the woman is so afraid to talk about it. It had everything, from gun fire, to fleeing from her home in Pakistan, to her brother and mother being taken as prisoners, and to giving birth in a forest on her way to India. When she first delivered the baby, her immediate response was to throw it away. You can imagine what trauma she was experiencing." What surprised Malhotra most was when the 90-year-old asked her what she would do with her story. "I said that I wanted to publish it. The woman's immediate response was, 'who will read this?'. They really think that nobody cares. But, this is the story that has shaped the future of contemporary India."

The jewellery Aanchal Malhotra is wearing, was made in the North-West Frontier Province and was given to her great-grandmother, Lajvanti Gulyani, by her in-laws on her wedding to Hari Chand Gulyani in the year 1919. But it could have been in the Gulyani family before that as well. Since she became a widow quite young and was a single mother at the time of Partition, it was carried by her to India in 1947 because she thought she would be able to sell it and earn money to put her children through school. She then gave it to Malhotra’s grandmother, who has now given it to her. Pic/Nishad Alam

Malhotra is the author of Remnants of Separation (HarperCollins India), a book that revisited the Partition through objects carried across the border, and the co-founder — along with Navdha Malhotra — of The Museum of Material Memory, a digital repository of material culture of the Indian subcontinent, tracing family histories and ethnography through heirlooms and objects of antiquity. Since the launch of the archive last year, the founders have put together over 35 heartwarming object stories. Closer home, photographer and graphic designer Anusha Yadav's Indian Memory Project — an online, visual, narrative-based archive, founded in 2010, which traces the history of the subcontinent via photographs and letters — has helped us see history in another light. There is also Paris-based perfumer Jahnvi Lakhota Nandan, whose recently-published book, Pukka Indian: 100 objects that Define India (Roli Books), documents the most coveted symbols and designs representing our culture, by tracing its origin and significance in our lives. All three projects while different in essence and form, have one common intent — to record untold stories from our history and preserve them for posterity. But, as Malhotra's subject asked her, why should anyone be curious?

The chakla and belan originated in 7,500 – 6,000 BCE in Punjab. At the time, this region was cultivating wheat and barley extensively. Rather than using the flatness of the chakla and the pressure of the belan to what we might expect to be used around the country to make flatbread, whatever the ingredient might be, it is only in this region of north India that the chakla and belan were used simply because wheat and barley lend themselves to kneading. What must have been perceived as a high-technology kitchen tool then, the chakla and belan soon spread to other parts of the country.

Celebrating the mundane
Nandan, an alumnus of the School of Art and Design at Tsukuba University, Japan, admits that her project stemmed out of her curiosity to find out about the designs that define us an Indian. "Design is a mirror of our attitudes and habits. Through the course of writing this book on Indian design, I found that uniquely Indian gestures like churning, combing and calculating were reflected in it," she writes in the book. From the dabba, agarbatti, and kulhad, to Babuline gripe water, most of the objects Nandan chose for the book, have "either been made or originated in India, or have an element that is very Indian, or are being used in a very Indian context".

This picture is of Purvi Sanghvi’s grandfather Dwarkadas Jivanlal Sanghvi (extreme right in a black coat) and his brother Vallabhdas Jivanlal Sanghvi with their business partners at a Pen Exhibition in Bombay around 1951. The family ran Wilson Pens that quickly rose to huge fame and became a preferred choice of pens across the country. All government offices, law court, used the Wilson pens. The Wilson Pen Family made the orange, thick-nibbed pen that wrote the most fundamental document that defines the state of India: The Constitution of India written by Dr Babasaheb Ambedkar.

It's while working on the book that Nandan realised how "our own homes are a repository of history". Here, she relays an incident when Shivani Gupta, the photographer for Pukka Indian, had been anxious about finding a mandira — a butter churner — that Nandan had mentioned in the book. "She went home, and realised that she had five of them in her kitchen. She didn't even know she was sitting on so much wealth." Nandan adds, "We don't tend to celebrate the mundane. What we celebrate are things that have obvious value, like jewellery, the beautification of the body or the exotic."

Object as a catalyst
Malhotra's interest in people's histories began while working on Remnants of Separation, which was an extension of her Master of Fine Arts thesis project for Concordia University, Canada. Malhotra's research began after she came across a gaz (a measuring device) and ghara (a pot), which belonged to her nana's family, and had crossed the border. "Sometimes the Partition is too traumatic to speak about. When I started my research, I didn't know where to begin or what I could ask, without sounding frivolous. The object became a catalyst to enter into that conversation. So, rather than me saying 'Oh! You lived through the Partition, that must be awful,' I was now asking relevant questions, like 'why did you choose to take this gold bangle with you?'. The object then, didn't become something that recessed into the background, but something around which the entire background was arranged."

That's when she and Navdha decided to start The Museum of Material Memory. The duo encourages everyone to contribute, provided the object is from or before the 1970s. The archive comprises everything from a 5-inch-long, mottled sewing needle to a chaddar with traditional baagh and phulkari embroidery and a former Class II Income-Tax officer's diary filled up with the repeated words 'Sri Rama Jayam', meaning Jai Sri Ram. Each post is accompanied with the story behind the object. "Material ethnography is so vastly explored in the West, especially when it comes to events of trauma and crisis. What we are recording here, will never be found in any textbook. We need active memoralisation, not just of traumatic events, but of our tradition and culture, which is primarily oral."

Not just for nostalgia's sake
The indianmemoryproject.com, says Yadav, started off as a book idea, where she wanted to collect old, wedding photographs. "I wanted to document the idea of weddings in different cultures, and explore the entire phenomena behind the crew that makes it possible," she says. "While the book didn't happen, the pictures stayed with me." That's how, her archive, a first-of-its-kind in India, took off. "If you are fascinated with history, you will know that India really is a melting pot. Every civilisation has passed through it. And so we have all kinds of DNA in us. And considering photography was discovered two centuries ago, we did have a lot of content to discuss," says Yadav.

She admits that it wasn't as easy to get people to share their photographs or talk about their stories. "But, there needs to be integrity, transparency and you need to earn the trust of your subject. When you have these value systems in place, people are more open. I always thought of the archive as an institution." Funding for the project has been tough, says the archivist. "When I began, I was very clear that I didn't want to become a trust. Unfortunately, that's the channel through which most of the money comes from. But, there's a server and maintenance cost and the site constantly needs to be upgraded. Now, I have started putting in requests for honorariums. The only way I will get money is through a private funder, who is fascinated with the idea, and wants to back it as well. Sometimes, when a good sum comes from my own work as a photographer, part of the profits go to it. At the end of the day, it is an unofficial record of history, and I'm doing my best to sustain it."
