The objective of deep metric learning (DML) is to learn embeddings that can capture semantic similarity and dissimilarity information among data points. Existing pairwise or tripletwise loss functions used in DML are known to suffer from slow convergence due to a large proportion of trivial pairs or triplets as the model improves. To improve this, ranking-motivated structured losses are proposed recently to incorporate multiple examples and exploit the structured information among them. They converge faster and achieve state-of-the-art performance. In this work, we unveil two limitations of existing ranking-motivated structured losses and propose a novel ranked list loss to solve both of them. First, given a query, only a fraction of data points is incorporated to build the similarity structure. To address this, we propose to build a set-based similarity structure by exploiting all instances in the gallery. The learning setting can be interpreted as few-shot retrieval: given a mini-batch, every example is iteratively used as a query, and the rest ones compose the galley to search, i.e., the support set in few-shot setting. The rest examples are split into a positive set and a negative set. For every mini-batch, the learning objective of ranked list loss is to make the query closer to the positive set than to the negative set by a margin. Second, previous methods aim to pull positive pairs as close as possible in the embedding space. As a result, the intraclass data distribution tends to be extremely compressed. In contrast, we propose to learn a hypersphere for each class in order to preserve useful similarity structure inside it, which functions as regularisation. Extensive experiments demonstrate the superiority of our proposal by comparing with the state-of-the-art methods on the fine-grained image retrieval task.

In this paper, we focus on the task of small-footprint keyword spotting under the far-field scenario. Far-field environments are commonly encountered in real-life speech applications, and it causes serve degradation of performance due to room reverberation and various kinds of noises. Our baseline system is built on the convolutional neural network trained with pooled data of both far-field and close-talking speech. To cope with the distortions, we adopt the multi-task learning scheme with alignment loss to reduce the mismatch between the embedding features learned from different domains of data. Experimental results show that our proposed method maintains the performance on close-talking speech and achieves significant improvement on the far-field test set.

We present a new mouse cursor designed to facilitate the use of the mouse by people with peripheral vision loss. The pointer consists of a collection of converging straight lines covering the whole screen and following the position of the mouse cursor. We measured its positive effects with a group of participants with peripheral vision loss of different kinds and we found that it can reduce by a factor of 7 the time required to complete a targeting task using the mouse. Using eye tracking, we show that this system makes it possible to initiate the movement towards the target without having to precisely locate the mouse pointer. Using Fitts' Law, we compare these performances with those of full visual field users in order to understand the relation between the accuracy of the estimated mouse cursor position and the index of performance obtained with our tool.

Various embodiments provide lossless compression of an enumeration space for genetic founder lines. In one embodiment, an input comprising a set of genetic founder lines and a maximum number of generations G is obtained. A set of genetic crossing templates of a height h is generated. A determination is made if at least a first genetic crossing template in the set of genetic crossing templates is redundant with respect to a second genetic crossing template in the set of genetic crossing templates. Based on the at least first genetic crossing template being redundant is redundant with respect to the second genetic crossing template, the at least first genetic crossing template is removed from the set of genetic crossing templates. This process of removing the at least first genetic crossing template from the set of genetic crossing templates the redundant creates an updated set of genetic crossing templates.

A method for reducing the coking time in the oven area near the door or end wall and for improving coke quality and situation of emissions by compensating for radiation losses through coke oven chamber doors and end walls is described. This compensation is accomplished by varying the height of the coal cake in the environment of the frontal coke oven chamber doors. The variation is achieved both by increasing or decreasing the coal cake over part of the length or over the entire length of the coke oven chamber door. The reduction in the height of the coal cake can be generated by omission of coal or coal compacts, the increase in height can be accomplished by stacking of coal and pressing or adding of coal compacts, with it also being envisaged to omit the pressing cycle so as to obtain a recess with a lower coal cake density which also has less heat radiation.

Very briefly, at the end of 2019 and the start of 2020, there were slightly more women on American nonfarm payrolls than men. That's no longer true. The historically disastrous April jobs report shows that the brunt of job losses fell on women. Women now account for around just under half — 49% — of American workers, and they accounted for 55% of the increase in job losses last month. One way of looking at why that matters that is to look at the gap that opened up between women's and men's unemployment last month. The below chart shows women's unemployment rate minus men's unemployment rate since 2007. Usually, the line bumps around near or just below zero — meaning men's unemployment is usually near or slightly higher than women's. But that spike on the far right shows how women's unemployment leapt to be 2.7 points higher than men's in April. Women had an unemployment rate of 16.2% to men's 13.5% last month. That's uncommon for a recession. The below chart is a longer view, and the
