2. Objective
• Generating topographic image with augmented DEAP dataset
• Classification of topographic images into Valence-Arousal model
• Training and validating Deep Learning algorithm using CNN

3. Workflow
Collecting Raw EEG
signals for different
Emotions
Noise Cancellation
Data Augmentation
and generation of 2D
Topographic Images
Feature Extraction
And Classification by
CNN

4. Data Augmentaion
Generation of 9X9
