| Outline of Final Research Achievements |
Toward a real-time co-adaptive BMI algorithm for providing flexible feedback schemes based on users' latent mental states, we developed reinforcement learning procedures to construct BMI decoders and representations for brain activities to infer the mental states. For the former topic, based on the weighted likelihood, we establish a theoretical framework to determine the optimal state modeling, namely the dimension of the mental states and their transition rule, to design an appropriate policy model, and to execute reinforcement learning simultaneously. For the latter topic, we proposed various generalizations of the standard feature extraction method CSP (common spatial pattern) to construct robust features against subject-to-subject variability and non-stationarity in brain signals. By integrating these element technologies, we implemented a BMI feedback device with portable EEG and a ball lamp, and tested its usefulness with a few subjects in a real-world environment.
