Saliency Based Control in Random Feature Networks
The ability to rapidly focus attention and react to salient environmental
features enables animals to move agiley through their habitats. To replicate
this kind of high-performance control of movement in synthetic systems, we
propose a new approach to feedback control that bases control actions on
randomly perceived features. Connections will be made with recent work
incorporating communication protocols into networked control systems. The
concepts of {\em random channel controllability} and {\em random channel
observability} for LTI control systems are introduced and studied.Comment: 9 pages, 2 figure
SeizureNet: Multi-Spectral Deep Feature Learning for Seizure Type Classification
Automatic classification of epileptic seizure types in electroencephalograms
(EEGs) data can enable more precise diagnosis and efficient management of the
disease. This task is challenging due to factors such as low signal-to-noise
ratios, signal artefacts, high variance in seizure semiology among epileptic
patients, and limited availability of clinical data. To overcome these
challenges, in this paper, we present SeizureNet, a deep learning framework
which learns multi-spectral feature embeddings using an ensemble architecture
for cross-patient seizure type classification. We used the recently released
TUH EEG Seizure Corpus (V1.4.0 and V1.5.2) to evaluate the performance of
SeizureNet. Experiments show that SeizureNet can reach a weighted F1 score of
up to 0.94 for seizure-wise cross validation and 0.59 for patient-wise cross
validation for scalp EEG based multi-class seizure type classification. We also
show that the high-level feature embeddings learnt by SeizureNet considerably
improve the accuracy of smaller networks through knowledge distillation for
applications with low-memory constraints
