Neural Latent Aligner: Cross-trial Alignment for Learning Representations of Complex, Naturalistic Neural Data

no code implementations12 Aug 2023 Cheol Jun Cho, Edward F. Chang, Gopala K. Anumanchipalli

The proposed framework learns more cross-trial consistent representations than the baselines, and when visualized, the manifold reveals shared neural trajectories across trials.

On Neural Phone Recognition of Mixed-Source ECoG Signals

no code implementations12 Dec 2019 Ahmed Hussen Abdelaziz, Shuo-Yiin Chang, Nelson Morgan, Erik Edwards, Dorothea Kolossa, Dan Ellis, David A. Moses, Edward F. Chang

The emerging field of neural speech recognition (NSR) using electrocorticography has recently attracted remarkable research interest for studying how human brains recognize speech in quiet and noisy surroundings.

Spiking Linear Dynamical Systems on Neuromorphic Hardware for Low-Power Brain-Machine Interfaces

no code implementations22 May 2018 David G. Clark, Jesse A. Livezey, Edward F. Chang, Kristofer E. Bouchard

Neuromorphic architectures achieve low-power operation by using many simple spiking neurons in lieu of traditional hardware.

Deep learning as a tool for neural data analysis: speech classification and cross-frequency coupling in human sensorimotor cortex

2 code implementations26 Mar 2018 Jesse A. Livezey, Kristofer E. Bouchard, Edward F. Chang

A fundamental challenge in neuroscience is to understand what structure in the world is represented in spatially distributed patterns of neural activity from multiple single-trial measurements.
