This PyTorch framework implements a number of gradient inversion attacks that breach privacy in federated learning scenarios,covering examples with small and large aggregation sizes and examples both vision and text domains. This includes implementations of recent work such as: But also a range of implementations of other attacks from optimization attacks (such as “Inverting Gradients” and “See through Gradients”) to recent analytic and recursive attacks. Jupyter notebook examples for these attacks can be found in the examples/ folder. Overview: This […]

This is the official implementation for the ICCV 2021 paper Learning Signed Distance Field for Multi-view Surface Reconstruction In this work, we introduce a novel neural surface reconstruction framework that leverages the knowledge of stereo matching and feature consistency to optimize the implicit surface representation. More specifically, we apply a signed distance field (SDF) and a surface light field to represent the scene geometry and appearance respectively. The SDF is directly supervised by geometry from stereo matching, and is refined […]

Growing up as an avid Call of Duty player, I was always curious about what factors led to a team winning or losing a match. Was it strictly based on the number of kills each player obtained? Was it who played the objective more? Or was it something different? Finally, after years of waiting, I decided that it was time to find my answers. Coupling my love for Call of Duty and my passion for data science, I began to […]

Using Global fishing watch’s data to build a machine learning model that can identify illegal fishing and poaching activities through satellite and geo-location data. Global fishing watch is a partnership between Google and Oceana to map all trackable fishing activity in world, in almost real time. This is a personal project using the data provided by global fishing watch. The data provided has vessel ids, types and coordinates of encountered vessels. Given same vessel type and are, a fishing vessel […]
