An Out-of-Domain Synapse Detection Challenge for Microwasp Brain Connectomes

no code implementations1 Feb 2023 Jingpeng Wu, Yicong Li, Nishika Gupta, Kazunori Shinomiya, Pat Gunn, Alexey Polilov, Hanspeter Pfister, Dmitri Chklovskii, Donglai Wei

The size of image stacks in connectomics studies now reaches the terabyte and often petabyte scales with a great diversity of appearance across brain regions and samples.

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.

Clustering is semidefinitely not that hard: Nonnegative SDP for manifold disentangling

no code implementations19 Jun 2017 Mariano Tepper, Anirvan M. Sengupta, Dmitri Chklovskii

In solving hard computational problems, semidefinite program (SDP) relaxations often play an important role because they come with a guarantee of optimality.
