Phases of two-dimensional spinless lattice fermions with first-quantized deep neural-network quantum states

no code implementations31 Jul 2020 James Stokes, Javier Robledo Moreno, Eftychios A. Pnevmatikakis, Giuseppe Carleo

First-quantized deep neural network techniques are developed for analyzing strongly coupled fermionic systems on the lattice.

A structured matrix factorization framework for large scale calcium imaging data analysis

11 code implementations9 Sep 2014 Eftychios A. Pnevmatikakis, Yuanjun Gao, Daniel Soudry, David Pfau, Clay Lacefield, Kira Poskanzer, Randy Bruno, Rafael Yuste, Liam Paninski

We present a structured matrix factorization approach to analyzing calcium imaging recordings of large neuronal ensembles.

Robust learning of low-dimensional dynamics from large neural ensembles

no code implementations NeurIPS 2013 David Pfau, Eftychios A. Pnevmatikakis, Liam Paninski

We show on model data that the parameters of latent linear dynamical systems can be recovered, and that even if the dynamics are not stationary we can still recover the true latent subspace.

Sparse nonnegative deconvolution for compressive calcium imaging: algorithms and phase transitions

no code implementations NeurIPS 2013 Eftychios A. Pnevmatikakis, Liam Paninski

We propose a compressed sensing (CS) calcium imaging framework for monitoring large neuronal populations, where we image randomized projections of the spatial calcium concentration at each timestep, instead of measuring the concentration at individual locations.
