RSN: Range Sparse Net for Efficient, Accurate LiDAR 3D Object Detection

CVPR 2021poster

The detection of 3D objects from LiDAR data is a critical component in most autonomous driving systems. Safe, high speed driving needs larger detection ranges, which are enabled by new LiDARs. These larger detection ranges require more efficient and accurate detection models. Towards this goal, we p…

Revisiting Spatial Invariance with Low-Rank Local Connectivity

ICML 2020poster

Convolutional neural networks are among the most successful architectures in deep learning with this success at least partially attributable to the efficacy of spatial invariance as an inductive bias. Locally connected layers, which differ from convolutional layers only in their lack of spatial inva…

Saccader: Improving Accuracy of Hard Attention Models for Vision

NeurIPS 2019poster

Although deep convolutional neural networks achieve state-of-the-art performance across nearly all image classification tasks, their decisions are difficult to interpret. One approach that offers some level of interpretability by design is \textit{hard attention}, which uses only relevant portions o…

Adversarial Examples that Fool both Computer Vision and Time-Limited Humans

NeurIPS 2018poster

Machine learning models are vulnerable to adversarial examples: small changes to images can cause computer vision models to make mistakes such as identifying a school bus as an ostrich. However, it is still an open question whether humans are prone to similar mistakes. Here, we address this question…

Large Margin Deep Networks for Classification

NeurIPS 2018poster

We present a formulation of deep learning that aims at producing a large margin classifier. The notion of \emc{margin}, minimum distance to a decision boundary, has served as the foundation of several theoretically profound and empirically successful results for both classification and regression t…
