Image-based Data Representations of Time Series: A Comparative Analysis in EEG Artifact Detection

no code implementations21 Dec 2023 Aaron Maiwald, Leon Ackermann, Maximilian Kalcher, Daniel J. Wu

We find that, while the choice of representation entails a choice within the tradeoff between bias and variance, certain representations are practically more effective in highlighting features which increase the signal-to-noise ratio of the data.

Binarized Neural Networks for Resource-Constrained On-Device Gait Identification

no code implementations30 Mar 2021 Daniel J. Wu, Avoy Datta, Vinay Prabhu

User authentication through gait analysis is a promising application of discriminative neural networks -- particularly due to the ubiquity of the primary sources of gait accelerometry, in-pocket cellphones.
