Abstract

Electroencephalography (EEG) is a non invasive technique for recording the scalp potentials that reflects the synchronous neural activity. This study explores a complete EEG to text framework that spans the data acquisition, preprocessing, feature extraction, supervised classification and for the symbolic natural language mapping. Using a public EEG emotion dataset, a Random Forest classifier achieved 87% accuracy in distinguishing between the three affective states (Positive, Neutral, Negative). Each predicted state is then represented by a short text templates to demonstrate the brain-to-text conversion. The results confirm that the time frequency features enable the meaningful decoding of emotional intent, while highlighting the limitations of current symbolic text generation. The Future directions include integration with a neural language models for context aware EEG-to-text generation.
