Revealing Vision-Language Integration in the Brain with Multimodal Networks

1 code implementation20 Jun 2024 Vighnesh Subramaniam, Colin Conwell, Christopher Wang, Gabriel Kreiman, Boris Katz, Ignacio Cases, Andrei Barbu

We operationalize sites of multimodal integration as regions where a multimodal vision-language model predicts recordings better than unimodal language, unimodal vision, or linearly-integrated language-vision models.

Population Transformer: Learning Population-level Representations of Intracranial Activity

no code implementations5 Jun 2024 Geeling Chau, Christopher Wang, Sabera Talukder, Vighnesh Subramaniam, Saraswati Soedarmadji, Yisong Yue, Boris Katz, Andrei Barbu

We present a self-supervised framework that learns population-level codes for intracranial neural recordings at scale, unlocking the benefits of representation learning for a key neuroscience recording modality.

Operator learning for hyperbolic partial differential equations

no code implementations29 Dec 2023 Christopher Wang, Alex Townsend

We construct the first rigorously justified probabilistic algorithm for recovering the solution operator of a hyperbolic partial differential equation (PDE) in two variables from input-output training pairs.

Learning a natural-language to LTL executable semantic parser for grounded robotics

no code implementations7 Aug 2020 Christopher Wang, Candace Ross, Yen-Ling Kuo, Boris Katz, Andrei Barbu

We take a step toward robots that can do the same by training a grounded semantic parser, which discovers latent linguistic representations that can be used for the execution of natural-language commands.

ObjectNet: A large-scale bias-controlled dataset for pushing the limits of object recognition models

no code implementations NeurIPS 2019 Andrei Barbu, David Mayo, Julian Alverio, William Luo, Christopher Wang, Dan Gutfreund, Josh Tenenbaum, Boris Katz

Although we focus on object recognition here, data with controls can be gathered at scale using automated tools throughout machine learning to generate datasets that exercise models in new ways thus providing valuable feedback to researchers.

Ranked #51 on Image Classification on ObjectNet (using extra training data)
