WildfireSpreadTS: A dataset of multi-modal time series for wildfire spread prediction

NeurIPS 2023poster

We present a multi-temporal, multi-modal remote-sensing dataset for predicting how active wildfires will spread at a resolution of 24 hours. The dataset consists of 13607 images across 607 fire events in the United States from January 2018 to October 2021. For each fire event, the dataset contains a…

Are All Linear Regions Created Equal?

AISTATS 2022poster

The number of linear regions has been studied as a proxy of complexity for ReLU networks. However, the empirical success of network compression techniques like pruning and knowledge distillation, suggest that in the overparameterized setting, linear regions density might fail to capture the effectiv…

Explanation-based Weakly-supervised Learning of Visual Relations with Graph Networks

ECCV 2020poster

Visual relationship detection is fundamental for holistic image understanding. However, the localization and classification of (subject, predicate, object) triplets remain challenging tasks, due to the combinatorial explosion of possible relationships, their long-tailed distribution in natural image…

Probabilistic Orientation Estimation with Matrix Fisher Distributions

NeurIPS 2020poster

This paper focuses on estimating probability distributions over the set of 3D ro- tations (SO(3)) using deep neural networks. Learning to regress models to the set of rotations is inherently difficult due to differences in topology between R^N and SO(3). We overcome this issue by using a neural netw…
