Classification via Tensor Decompositions of Echo State Networks

no code implementations23 Aug 2017 Ashley Prater

This work proposes a tensor-based supervised classification method on echo state network data that preserves and exploits the multidimensional nature of the hidden layer states.

Comparison of echo state network output layer classification methods on noisy data

no code implementations13 Mar 2017 Ashley Prater

A strength of echo state networks is the simple method used to train the output layer - typically a collection of linear readout weights found using a least squares approach.

Reservoir computing for spatiotemporal signal classification without trained output weights

no code implementations11 Apr 2016 Ashley Prater

Reservoir computing is a recently introduced machine learning paradigm that has been shown to be well-suited for the processing of spatiotemporal data.

Finding Dantzig selectors with a proximity operator based fixed-point algorithm

no code implementations19 Feb 2015 Ashley Prater, Lixin Shen, Bruce W. Suter

In this paper, we study a simple iterative method for finding the Dantzig selector, which was designed for linear regression problems.

Separation of undersampled composite signals using the Dantzig selector with overcomplete dictionaries

no code implementations20 Jan 2015 Ashley Prater, Lixin Shen

In this paper, we propose using the Dantzig selector model incorporating an overcomplete dictionary to separate a noisy undersampled collection of composite signals, and present an algorithm to efficiently solve the model.
