Motion Style Transfer: Modular Low-Rank Adaptation for Deep Motion Forecasting

1 code implementation6 Nov 2022 Parth Kothari, Danya Li, Yuejiang Liu, Alexandre Alahi

To this end, we introduce two components that exploit our prior knowledge of motion style shifts: (i) a low-rank motion style adapter that projects and adjusts the style features at a low-dimensional bottleneck; and (ii) a modular adapter strategy that disentangles the features of scene context and motion history to facilitate a fine-grained choice of adaptation layers.

TTT++: When Does Self-Supervised Test-Time Training Fail or Thrive?

1 code implementation NeurIPS 2021 Yuejiang Liu, Parth Kothari, Bastien Van Delft, Baptiste Bellot-Gurlet, Taylor Mordan, Alexandre Alahi

In this work, we first provide an in-depth look at its limitations and show that TTT can possibly deteriorate, instead of improving, the test-time performance in the presence of severe distribution shifts.

DriverGym: Democratising Reinforcement Learning for Autonomous Driving

no code implementations12 Nov 2021 Parth Kothari, Christian Perone, Luca Bergamini, Alexandre Alahi, Peter Ondruska

Despite promising progress in reinforcement learning (RL), developing algorithms for autonomous driving (AD) remains challenging: one of the critical issues being the absence of an open-source platform capable of training and effectively validating the RL policies on real-world data.

Interpretable Social Anchors for Human Trajectory Forecasting in Crowds

no code implementations CVPR 2021 Parth Kothari, Brian Sifringer, Alexandre Alahi

Human trajectory forecasting in crowds, at its core, is a sequence prediction problem with specific challenges of capturing inter-sequence dependencies (social interactions) and consequently predicting socially-compliant multimodal distributions.
