Testing for context-dependent changes in neural encoding in naturalistic experiments

no code implementations17 Nov 2022 Yenho Chen, Carl W. Harris, Xiaoyu Ma, Zheng Li, Francisco Pereira, Charles Y. Zheng

We propose a decoding-based approach to detect context effects on neural codes in longitudinal neural recording data.

VICE: Variational Interpretable Concept Embeddings

1 code implementation2 May 2022 Lukas Muttenthaler, Charles Y. Zheng, Patrick McClure, Robert A. Vandermeulen, Martin N. Hebart, Francisco Pereira

This paper introduces Variational Interpretable Concept Embeddings (VICE), an approximate Bayesian method for embedding object concepts in a vector space using data collected from humans in a triplet odd-one-out task.

Revealing interpretable object representations from human behavior

no code implementations ICLR 2019 Charles Y. Zheng, Francisco Pereira, Chris I. Baker, Martin N. Hebart

To study how mental object representations are related to behavior, we estimated sparse, non-negative representations of objects using human behavioral judgments on images representative of 1, 854 object categories.


Distributed Weight Consolidation: A Brain Segmentation Case Study

no code implementations NeurIPS 2018 Patrick McClure, Charles Y. Zheng, Jakub R. Kaczmarzyk, John A. Lee, Satrajit S. Ghosh, Dylan Nielson, Peter Bandettini, Francisco Pereira

Collecting the large datasets needed to train deep neural networks can be very difficult, particularly for the many applications for which sharing and pooling data is complicated by practical, ethical, or legal concerns.

Estimating mutual information in high dimensions via classification error

no code implementations16 Jun 2016 Charles Y. Zheng, Yuval Benjamini

Multivariate pattern analyses approaches in neuroimaging are fundamentally concerned with investigating the quantity and type of information processed by various regions of the human brain; typically, estimates of classification accuracy are used to quantify information.

Deconvolution of High Dimensional Mixtures via Boosting, with Application to Diffusion-Weighted MRI of Human Brain

no code implementations NeurIPS 2014 Charles Y. Zheng, Franco Pestilli, Ariel Rokem

Diffusion-weighted magnetic resonance imaging (DWI) and fiber tractography are the only methods to measure the structure of the white matter in the living human brain.
