Adaptive whitening in neural populations with gain-modulating interneurons

Introduction

This repo is associated with our project on adaptive online whitening using overcomplete projections and gain modulation. We presented this as a poster at COSYNE 2023 [1], and as a manuscript/poster at ICML 2023 [2].

Installation

Pull this repo, cd to it, and pip install -e .

Code to reproduce figures and experiments

The frame_whitening/ directory contains code central to the project, including the algorithm, and utility functions. The figures/ directory contains the ipynb files to reproduce the figures in the paper. These can be viewed online directly.
