About

Dr. Matthew Roos is a neuroscientist and engineer. He currently works with deep learning models for computer vision. His interests include advancing AI based on neuroscience, neuroevolution and artificial life, and brain-computer interfaces.

Prior to Binary Cognition, Dr. Roos worked at the Johns Hopkins University Applied Physics Lab. His work involved (1) utilizing neuromimetic AI models for processing of images, video, speech, etc., (2) developing brain-computer interfaces and exploring their applications, and (3) using neuroscience to predict and/or improve individual human performance on a range of tasks.

Dr. Roos obtained his PhD at the Johns Hopkins University Department of Neuroscience, where he studied the function of inhibitory neurotransmitters in the rodent auditory system.

Code

Reilly, et al. (2017) describes and justifies the Neural Reconstruction Integrity (NRI) metric for assessing the connectivity of reconstructed neural networks. Code that computes the metric and applies it to a toy example is found here.

Caceres, et al. (2017) explores a variety of feature selection methods for zero-shot learning, applied to human electrocorticography data. Code is available upon request.

Roos and May (2012) describes metrics used to characterize and classify units in the anteroventral cochlear nucleus of the mouse. This MATLAB code on GitHub computes the metrics.
