Better Set Representations For Relational Reasoning

NeurIPS 2020poster

Incorporating relational reasoning into neural networks has greatly expanded their capabilities and scope. One defining trait of relational reasoning is that it operates on a set of entities, as opposed to standard vector representations. Existing end-to-end approaches for relational reasoning typic…

Neural Manifold Ordinary Differential Equations

NeurIPS 2020poster

To better conform to data geometry, recent deep generative modelling techniques adapt Euclidean constructions to non-Euclidean spaces. In this paper, we study normalizing flows on manifolds. Previous work has developed flow models for specific cases; however, these advancements hand craft layers on…

DCAN: Dual Channel-wise Alignment Networks for Unsupervised Scene Adaptation

ECCV 2018poster

Harvesting dense pixel-level annotations to train deep neural networks for semantic segmentation is extremely expensive and unwieldy at scale. While learning from synthetic data where labels are readily available sounds promising, performance degrades significantly when testing on novel realistic da…

Learning From Synthetic Data: Addressing Domain Shift for Semantic Segmentation

CVPR 2018poster

Visual Domain Adaptation is a problem of immense importance in computer vision. Previous approaches showcase the inability of even deep neural networks to learn informative representations across domain shift. This problem is more severe for tasks where acquiring hand labeled data is extremely hard…

Adaptive RNN Tree for Large-Scale Human Action Recognition

ICCV 2017poster

In this work, we present the RNN Tree (RNN-T), an adaptive learning framework for skeleton based human action recognition. Our method categorizes action classes and uses multiple Recurrent Neural Networks (RNNs) in a tree-like hierarchy. The RNNs in RNN-T are co-trained with the action category hier…

Guided Perturbations: Self-Corrective Behavior in Convolutional Neural Networks

ICCV 2017poster

Convolutional Neural Networks have been a subject of great importance over the past decade and great strides have been made in their utility for producing state of the art performance in many computer vision problems. However, the behavior of deep networks is yet to be fully understood and is still…
