I. Introduction
Graph Signal Processing (GSP) studies the signals having irregular domain residing on the nodes of a graph instead of regular intervals such as grids. To provide a nice compact format to encode the structure within the data, new tools are being developed in GSP [1]. Among various fields such as social network, gesture recognition, road network etc. Human Brain provides structure which can be easily analysed in graph signal domain. It provides the most inclusive information of psychological state of -a person. Epilepsy is one such kind of seizure that affects various psychological and physical functions. It is a neurological disorder where sudden abnormal reactions occur in the brain producing fluctuations which are captured in EEG signals.
