q1.py: Using EEG data, developing a prediction model for eyes open and closed task. Data is raw at 256Hz,4 channels epoched and labelled. Various steps were used:
- Data was cleaned, filtered and then ICA was done.
- Alpha power was extracted.
- KNN classifier was used with 10 fold cross validation to develop a classification model.
q2.py: 1)Time -frequency decompostion of eeg data. 2) Temporal analysis of the dominant freq and see how it evolves over the tasks.
q3.py:
- Charactorizing signal components into various artifacts like eye blinks, muscle activity, eye movement, eyes open/closed.
- Performing ICA and then analyzing its time-frequency activity to look for the standard signatures of the above artifacts.
