MoCapAct: A Multi-Task Dataset for Simulated Humanoid Control

NeurIPS 2022accept

Simulated humanoids are an appealing research domain due to their physical capabilities. Nonetheless, they are also challenging to control, as a policy must drive an unstable, discontinuous, and high-dimensional physical system. One widely studied approach is to utilize motion capture (MoCap) data t…

Uni[MASK]: Unified Inference in Sequential Decision Problems

NeurIPS 2022accept

Randomly masking and predicting word tokens has been a successful approach in pre-training language models for a variety of downstream tasks. In this work, we observe that the same idea also applies naturally to sequential decision making, where many well-studied tasks like behavior cloning, offline…

ALFWorld: Aligning Text and Embodied Environments for Interactive Learning

ICLR 2021poster

Given a simple request like Put a washed apple in the kitchen fridge, humans can reason in purely abstract terms by imagining action sequences and scoring their likelihood of success, prototypicality, and efficiency, all without moving a muscle. Once we see the kitchen in question, we can update our…

Reading and Acting while Blindfolded: The Need for Semantics in Text Game Agents

NAACL 2021long

Text-based games simulate worlds and interact with players using natural language. Recent work has used them as a testbed for autonomous language-understanding agents, with the motivation being that understanding the meanings of words or semantics is a key component of how humans understand, reason,…

Graph Constrained Reinforcement Learning for Natural Language Action Spaces

ICLR 2020poster

Interactive Fiction games are text-based simulations in which an agent interacts with the world purely through natural language. They are ideal environments for studying how to extend reinforcement learning agents to meet the challenges of natural language understanding, partial observability, and a…

Learning Calibratable Policies using Programmatic Style-Consistency

ICML 2020poster

We study the problem of controllable generation of long-term sequential behaviors, where the goal is to calibrate to multiple behavior styles simultaneously. In contrast to the well-studied areas of controllable generation of images, text, and speech, there are two questions that pose significant ch…

Working Memory Graphs

ICML 2020poster

Transformers have increasingly outperformed gated RNNs in obtaining new state-of-the-art results on supervised tasks involving text sequences. Inspired by this trend, we study the question of how Transformer-based models can improve the performance of sequential decision-making agents. We present th…

Leveraging Grammar and Reinforcement Learning for Neural Program Synthesis

ICLR 2018poster

Program synthesis is the task of automatically generating a program consistent with a specification. Recent years have seen proposal of a number of neural approaches for program synthesis, many of which adopt a sequence generation paradigm similar to neural machine translation, in which sequence-to-…

Beyond Short Snippets: Deep Networks for Video Classification

CVPR 2015poster

Convolutional neural networks (CNNs) have been exten- sively applied for image recognition problems giving state- of-the-art results on recognition, detection, segmentation and retrieval. In this work we propose and evaluate several deep neural network architectures to combine image infor- mation ac…
