Projects (Scientific)

Neureka Seizure Challenge 2020 1st place submission


Code developed as part of team Biomed Irregulars from STADIUS research group of KU Leuven. Winners of Neureka Seizure prediction challenge 2020

Scripts and notebooks developed by the team Biomed Irregulars from STADIUS research group of KU Leuven. The winning submission to Neureka 2020 epilepsy challenge(results). The challenge was to develop a model to detect epileptic seizures in the TUH Seizure Dataset.

Channel selection in least-squares (LS) problem


A fast and easilty interpretable channel (feature) selection in LS-based problems.

MATLAB and python code implementing utility-based channel selection for least-squares(LS) problems. Developed to be applied in EEG-based auditory attention decoding problems, the tool can be used for any LS problem. In neural-decoding, the channel selection method can be used in neural decoding of speech for future neuro-steered hearing aids. It has been also used for feature-selection in classification.

A python toolbox for doctors, practioners and researchers implementing a web application to read, analyse and visualize EEG collected and distributed using various formats.

There are plenty of toolboxes available online for EEG analysis in python. However, most of these toolboxes involve a steep learning curve. Moreover, easy, interactive visualization is a challenge of many such toolboxes. This toolbox is start of a journey towards a simple, easily useable toolbox in python which will help researchers, doctors and practitioners use a web browser to read, analyse and visualize EEG recorded and distributed in various formats.

Projects (Recreational)

An Edge-AI project. Real-time sound classification model deployed on a Raspberry Pi. Github link https://github.com/mabhijithn/urbannoise-edgeai

Impact of goal scorers in football


Analysing the impact of goal scorers of the English Premier League in 21st century.

An interactive tool to visualize the different goal scorers based on the impact of their goals on their team’s results or performance in a match. The entire data used in the visualization was collected personally with the help web-scraping using Beautiful Soup and some nifty python based structuring of the data.
