Abstract
In this talk, we will be talking about some of our recent work in understanding and creating new architectures for convolutional networks, which have achieved great success in computer vision in the last decade but might be getting to a point that might require an overhaul to drive deep learning to a new level. We will start by summarizing our various endeavors on understanding the mechanisms of decision-making convolutional networks and visualizing those to the users. Afterwards, we would introduce our proposed PointConv that overcomes many limitations of traditional convolutional networks by allowing convolution to be applied on point sets that are distributed arbitrarily in a low-dimensional Euclidean space. Finally, we would introduce a new approach to better estimate uncertainty in neural networks, applicable to many scenarios such as outlier detection, adversarial robustness and better exploration in reinforcement learning.
