Abstract
A method and system for generating an optimal audio stimulus for achieving a target brain state value for a brain state. The method and system can be used to generate one or more brain state models which can decode brain activity signals to predict brain state values. The brain state models can be applied to brain activity signals captured while users are performing tasks with an audio stimulus. Audio features of the audio stimulus can be extracted. An audio-brain model can be trained on the predicted brain state values and the audio features. From the trained audio-brain model, the optimal audio stimulus can be generated.
Claims11
A method for brain state optimization, the method comprising:
- prompting a set of users to perform a sequence of tasks in coordination with provision of a stimulus;
- recording a brain activity signal for each user of the set of users while the user is performing the sequence of tasks;
- receiving a reported brain state value, reported by each user of the set of users, for each task of the sequence of tasks;
- training a first brain state model based on the brain activity signals recorded from the set of users and the reported brain state values, wherein the first brain state model is configured to process an input brain activity signal and to output a predicted brain state value based on the input brain activity signal;
- applying the first brain state model to predict a first brain state value for each user and each task;
- extracting a set of features from the stimulus;
- training a stimulus-brain model based on the set of features and the first brain state values over the set of users and the sequence of tasks;
- and
- generating an optimal stimulus to achieve a target brain state value based on the trained stimulus-brain model.
