A Geometric Analysis of Time Series Leading to Information Encoding and a New Entropy Measure
Kaushik Majumdar, Srinath Jayachandran
A time series is uniquely represented by its geometric shape, which also carries information. A time series can be modelled as the trajectory of a particle moving in a force field…
Ictal and Post Ictal Impaired Consciousness due to Enhanced Mutual Information in Temporal Lobe Epilepsy
Puneet Dheer, Sandipan Pati, Srinath Jayachandran +1
Seizure and synchronization are related to each other in complex manner. Altered synchrony has been implicated in loss of consciousness during partial seizures. However, the mechan…
Semantic Information Encoding in One Dimensional Time Domain Signals
Kaushik Majumdar, Srinath Jayachandran
A one dimensional time domain analog signal s(t) can be visualized as a trajectory of a moving particle in a force field with one degree of freedom. Then the power of the particle…
An Investigation into the Mathematical Nature of Electrophysiological Signals with Applications
Kaushik Majumdar, Anagh Pathak, Viswadeep Sarangi
In this work we have proposed a rigorous mathematical definition for the one dimensional time domain electrophysiological signals and established its relationship with two of the t…
Comparison of feature extraction and dimensionality reduction methods for single channel extracellular spike sorting
Anupam Mitra, Anagh Pathak, Kaushik Majumdar
Spikes in the membrane electrical potentials of neurons play a major role in the functioning of nervous systems of animals. Obtaining the spikes from different neurons has been a c…
A Novel Matrix Representation of Discrete Biomedical Signals
Aditya Ramesh, Anagh Pathak, Kaushik Majumdar
In this work we propose a novel symmetric square matrix representation of one or more digital signals of finite equal length. For appropriate window length and sliding paradigm thi…
