Harnessing small projectors and multiple views for efficient vision pretraining

NeurIPS 2024poster

Recent progress in self-supervised (SSL) visual representation learning has led to the development of several different proposed frameworks that rely on augmentations of images but use different loss functions. However, there are few theoretically grounded principles to guide practice, so practical…

Motif: Intrinsic Motivation from Artificial Intelligence Feedback

ICLR 2024poster

Exploring rich environments and evaluating one's actions without prior knowledge is immensely challenging. In this paper, we propose Motif, a general method to interface such prior knowledge from a Large Language Model (LLM) with an agent. Motif is based on the idea of grounding LLMs for decision-ma…

TorchRL: A data-driven decision-making library for PyTorch

ICLR 2024spotlight

PyTorch has ascended as a premier machine learning framework, yet it lacks a native and comprehensive library for decision and control tasks suitable for large development teams dealing with complex real-world data and environments. To address this issue, we propose TorchRL, a generalistic control l…

When should we prefer Decision Transformers for Offline Reinforcement Learning?

ICLR 2024poster

Offline reinforcement learning (RL) allows agents to learn effective, return-maximizing policies from a static dataset. Three popular algorithms for offline RL are Conservative Q-Learning (CQL), Behavior Cloning (BC), and Decision Transformer (DT), from the class of Q-Learning, Imitation Learning, a…

VIP: Towards Universal Visual Reward and Representation via Value-Implicit Pre-Training

ICLR 2023top-25%

Reward and representation learning are two long-standing challenges for learning an expanding set of robot manipulation skills from sensory observations. Given the inherent cost and scarcity of in-domain, task-specific robot data, learning from large, diverse, offline human videos has emerged as a p…

Robust Policy Learning over Multiple Uncertainty Sets

ICML 2022spotlight

Reinforcement learning (RL) agents need to be robust to variations in safety-critical environments. While system identification methods provide a way to infer the variation from online experience, they can fail in settings where fast identification is not possible. Another dominant approach is robus…

The Neural Race Reduction: Dynamics of Abstraction in Gated Networks

ICML 2022spotlight

Our theoretical understanding of deep learning has not kept pace with its empirical success. While network architecture is known to be critical, we do not yet understand its effect on learned representations and network behavior, or how this architecture should reflect task structure.In this work, w…

Learning Robust State Abstractions for Hidden-Parameter Block MDPs

ICLR 2021poster

Many control tasks exhibit similar dynamics that can be modeled as having common latent structure. Hidden-Parameter Markov Decision Processes (HiP-MDPs) explicitly model this structure to improve sample efficiency in multi-task settings. However, this setting makes strong assumptions on the observab…

Recurrent Independent Mechanisms

ICLR 2021spotlight

We explore the hypothesis that learning modular structures which reflect the dynamics of the environment can lead to better generalization and robustness to changes that only affect a few of the underlying causes. We propose Recurrent Independent Mechanisms (RIMs), a new recurrent architecture in wh…

Reinforcement Learning with Competitive Ensembles of Information-Constrained Primitives

ICLR 2020poster

Reinforcement learning agents that operate in diverse and complex environments can benefit from the structured decomposition of their behavior. Often, this is addressed in the context of hierarchical reinforcement learning, where the aim is to decompose a policy into lower-level primitives or option…
