In particular, stochastic gradient methods can suffer from high variance, limiting their convergence speed. While variance reduction techniques exist in the finite case, they are rarer in the online case. We demonstrate how an increasing momentum offers variance reduction in the online case, at the expense of bias, and how that bias can be countered by an extrapolation step. The resulting algorithm differs from iterate averaging in only a factor, but, in the context of the minimization of a quadratic function, this difference is enough to lead to the first algorithm converging both linearly in the noiseless and sublinearly in the homoscedastic noise case when using a constant stepsize.
May 25 20181:30 PMAdrià RecasensMITAA3195Where are they looking?streamedHumans have the remarkable ability to follow the gaze of other people to identify what they are looking at. Following eye gaze, or gaze-following, is an important ability that allows us to understand what other people are thinking, the actions they are performing, and even predict what they might do next. Despite the importance of this topic, this problem has only been studied in limited scenarios within the computer vision community. In this talk I will present a deep neural network-based approach for gaze-following. Given an image and the location of a head, our approach follows the gaze of the person and identifies the object being looked at. Furthermore, I will also introduce GazeNet, a deep neural-network to predict the 3D direction of a person's gaze from the full 360 degrees. To complement GazeNet, I will present a novel saliency-based sampling layer for neural networks, the Saliency Sampler, which helps to improve the spatial sampling of input data for an arbitrary task. Our differentiable layer can be added as a preprocessing block to existing task networks and trained altogether in an end-to-end fashion. The effect of the layer is to efficiently estimate how to sample from the original data in order to boost task performance. For example, for the gaze-tracking task in which the original data might range in size up to several megapixels, but where the desired input images to the task network are much smaller, our layer learns how best to sample from the underlying high resolution data in a manner which preserves task-relevant information better than uniform downsampling.
