The Neuron as a Direct Data-Driven Controller

no code implementations3 Jan 2024 Jason Moore, Alexander Genkin, Magnus Tournoy, Joshua Pughe-Sanford, Rob R. de Ruyter van Steveninck, Dmitri B. Chklovskii

In the quest to model neuronal function amidst gaps in physiological data, a promising strategy is to develop a normative theory that interprets neuronal physiology as optimizing a computational objective.

Neural optimal feedback control with local learning rules

2 code implementations NeurIPS 2021 Johannes Friedrich, Siavash Golkar, Shiva Farashahi, Alexander Genkin, Anirvan M. Sengupta, Dmitri B. Chklovskii

This network performs system identification and Kalman filtering, without the need for multiple phases with distinct update rules or the knowledge of the noise covariances.

A Neural Network for Semi-Supervised Learning on Manifolds

no code implementations21 Aug 2019 Alexander Genkin, Anirvan M. Sengupta, Dmitri Chklovskii

Here, we propose a feed-forward neural network capable of semi-supervised learning on manifolds without using an explicit graph representation.

Manifold-tiling Localized Receptive Fields are Optimal in Similarity-preserving Neural Networks

1 code implementation NeurIPS 2018 Anirvan Sengupta, Cengiz Pehlevan, Mariano Tepper, Alexander Genkin, Dmitri Chklovskii

Many neurons in the brain, such as place cells in the rodent hippocampus, have localized receptive fields, i. e., they respond to a small neighborhood of stimulus space.

Distributed Coordinate Descent for Generalized Linear Models with Regularization

1 code implementation7 Nov 2016 Ilya Trofimov, Alexander Genkin

Generalized linear model with $L_1$ and $L_2$ regularization is a widely used technique for solving classification, class probability estimation and regression problems.
