Neural Pseudo-Label Optimism for the Bank Loan Problem

no code implementations NeurIPS 2021 Aldo Pacchiano, Shaun Singh, Edward Chou, Alexander C. Berg, Jakob Foerster

The lender only observes whether a customer will repay a loan if the loan is issued to begin with, and thus modeled decisions affect what data is available to the lender for future decisions.

SentiNet: Detecting Physical Attacks Against Deep Learning Systems

1 code implementation2 Dec 2018 Edward Chou, Florian Tramèr, Giancarlo Pellegrino, Dan Boneh

By leveraging the neural network's susceptibility to attacks and by using techniques from model interpretability and object detection as detection mechanisms, SentiNet turns a weakness of a model into a strength.

Privacy-Preserving Action Recognition for Smart Hospitals using Low-Resolution Depth Images

no code implementations25 Nov 2018 Edward Chou, Matthew Tan, Cherry Zou, Michelle Guo, Albert Haque, Arnold Milstein, Li Fei-Fei

Computer-vision hospital systems can greatly assist healthcare workers and improve medical facility treatment, but often face patient resistance due to the perceived intrusiveness and violation of privacy associated with visual surveillance.

Neural Graph Matching Networks for Fewshot 3D Action Recognition

no code implementations ECCV 2018 Michelle Guo, Edward Chou, De-An Huang, Shuran Song, Serena Yeung, Li Fei-Fei

We propose Neural Graph Matching (NGM) Networks, a novel framework that can learn to recognize a previous unseen 3D action class with only a few examples.

Temporal Modular Networks for Retrieving Complex Compositional Activities in Videos

no code implementations ECCV 2018 Bingbin Liu, Serena Yeung, Edward Chou, De-An Huang, Li Fei-Fei, Juan Carlos Niebles

A major challenge in computer vision is scaling activity understanding to the long tail of complex activities without requiring collecting large quantities of data for new actions.

AI Blue Book: Vehicle Price Prediction using Visual Features

1 code implementation29 Mar 2018 Richard R. Yang, Steven Chen, Edward Chou

In this work, we build a series of machine learning models to predict the price of a product given its image, and visualize the features that result in higher or lower price predictions.
