Non-linear dimensionality reduction on extracellular waveforms reveals cell type diversity in premotor cortex

open access: yeseLife, 2021
Cortical circuits are thought to contain a large number of cell types that coordinate to produce behavior. Current in vivo methods rely on clustering of specified features of extracellular waveforms to identify putative cell types, but these capture only

Training Echo State Networks with Regularization through Dimensionality Reduction [PDF]

open access: yes, 2016
In this paper we introduce a new framework to train an Echo State Network to predict real valued time-series. The method consists in projecting the output of the internal layer of the network on a space with lower dimensionality, before training the ...

Simultaneous Learning of Nonlinear Manifold and Dynamical Models for High-dimensional Time Series [PDF]

open access: yes, 2007
The goal of this work is to learn a parsimonious and informative representation for high-dimensional time series. Conceptually, this comprises two distinct yet tightly coupled tasks: learning a low-dimensional manifold and modeling the dynamical process.
