A Vision Check-up for Language Models

no code implementations3 Jan 2024 Pratyusha Sharma, Tamar Rott Shaham, Manel Baradad, Stephanie Fu, Adrian Rodriguez-Munoz, Shivam Duggal, Phillip Isola, Antonio Torralba

Although LLM-generated images do not look like natural images, results on image generation and the ability of models to correct these generated images indicate that precise modeling of strings can teach language models about numerous aspects of the visual world.

Image Generation Representation Learning

The Truth is in There: Improving Reasoning in Language Models with Layer-Selective Rank Reduction

1 code implementation21 Dec 2023 Pratyusha Sharma, Jordan T. Ash, Dipendra Misra

Transformer-based Large Language Models (LLMs) have become a fixture in modern machine learning.

Learning adaptive planning representations with natural language guidance

no code implementations13 Dec 2023 Lionel Wong, Jiayuan Mao, Pratyusha Sharma, Zachary S. Siegel, Jiahai Feng, Noa Korneev, Joshua B. Tenenbaum, Jacob Andreas

Effective planning in the real world requires not only world knowledge, but the ability to leverage that knowledge to build the right representation of the task at hand.

Pushdown Layers: Encoding Recursive Structure in Transformer Language Models

1 code implementation29 Oct 2023 Shikhar Murty, Pratyusha Sharma, Jacob Andreas, Christopher D. Manning

Recursion is a prominent feature of human language, and fundamentally challenging for self-attention due to the lack of an explicit recursive-state tracking mechanism.

Pseudointelligence: A Unifying Framework for Language Model Evaluation

no code implementations18 Oct 2023 Shikhar Murty, Orr Paradise, Pratyusha Sharma

With large language models surpassing human performance on an increasing number of benchmarks, we must take a principled approach for targeted evaluation of model capabilities.

Grokking of Hierarchical Structure in Vanilla Transformers

1 code implementation30 May 2023 Shikhar Murty, Pratyusha Sharma, Jacob Andreas, Christopher D. Manning

When analyzing the relationship between model-internal properties and grokking, we find that optimal depth for grokking can be identified using the tree-structuredness metric of \citet{murty2023projections}.

LaMPP: Language Models as Probabilistic Priors for Perception and Action

no code implementations3 Feb 2023 Belinda Z. Li, William Chen, Pratyusha Sharma, Jacob Andreas

Language models trained on large text corpora encode rich distributional information about real-world environments and action sequences.

Characterizing Intrinsic Compositionality in Transformers with Tree Projections

no code implementations2 Nov 2022 Shikhar Murty, Pratyusha Sharma, Jacob Andreas, Christopher D. Manning

To evaluate this possibility, we describe an unsupervised and parameter-free method to \emph{functionally project} the behavior of any transformer into the space of tree-structured networks.

Skill Induction and Planning with Latent Language

no code implementations ACL 2022 Pratyusha Sharma, Antonio Torralba, Jacob Andreas

We evaluate this approach in the ALFRED household simulation environment, providing natural language annotations for only 10% of demonstrations.

Intelligent Carpet: Inferring 3D Human Pose From Tactile Signals

no code implementations CVPR 2021 Yiyue Luo, Yunzhu Li, Michael Foshey, Wan Shou, Pratyusha Sharma, Tomas Palacios, Antonio Torralba, Wojciech Matusik

In this work, leveraging such tactile interactions, we propose a 3D human pose estimation approach using the pressure maps recorded by a tactile carpet as input.

Cetacean Translation Initiative: a roadmap to deciphering the communication of sperm whales

no code implementations17 Apr 2021 Jacob Andreas, Gašper Beguš, Michael M. Bronstein, Roee Diamant, Denley Delaney, Shane Gero, Shafi Goldwasser, David F. Gruber, Sarah de Haas, Peter Malkin, Roger Payne, Giovanni Petri, Daniela Rus, Pratyusha Sharma, Dan Tchernov, Pernille Tønnesen, Antonio Torralba, Daniel Vogt, Robert J. Wood

We posit that machine learning will be the cornerstone of future collection, processing, and analysis of multimodal streams of data in animal communication studies, including bioacoustic, behavioral, biological, and environmental data.

Third-Person Visual Imitation Learning via Decoupled Hierarchical Controller

1 code implementation NeurIPS 2019 Pratyusha Sharma, Deepak Pathak, Abhinav Gupta

We study a generalized setup for learning from demonstration to build an agent that can manipulate novel objects in unseen scenarios by looking at only a single video of human demonstration from a third-person perspective.

Multiple Interactions Made Easy (MIME): Large Scale Demonstrations Data for Imitation

no code implementations16 Oct 2018 Pratyusha Sharma, Lekha Mohan, Lerrel Pinto, Abhinav Gupta

In order to make progress and capture the space of manipulation, we would need to collect a large-scale dataset of diverse tasks such as pouring, opening bottles, stacking objects etc.
