System and method for brain modelling

A system for brain modelling, the system comprising:

• a client computing device;
• a bio-signal sensor, wherein the bio-signal sensor is in communication with the client computing device;
• a user effector, wherein the user effector is in communication with the client computing device;
• a server comprising a memory storing a plurality of user brain models, wherein the server is in communication with the client computing device;
• the client computing device configured to:
• generate time-coded bio-signal data associated with a user using the bio-signal sensor;
• generate time-coded stimulus event data;
• transmit the time-coded bio-signal data and the time-coded stimulus event data to the server;
• the server configured to:
• receive the time-coded bio-signal data;
• receive the time-coded stimulus event data;
• project the time-coded bio-signal data into a lower dimensioned feature space;
• extract features from the lower dimensioned feature space that correspond to time codes of the time-coded stimulus event data to identify a brain response;
• generate a training data set for the brain response using the features;
• generate a brain model by transfer learning from one or more similar users by:
• comparing attributes of users to identify the one or more similar users;
• pooling data of the one or more similar users stored in the memory;
• and
• training the brain model from a base brain model using the pooled data by modifying the parameters of the base brain model;
• and
• train the brain model using the training set by modifying the parameters of the brain model, the trained brain model unique to the user;
• at least one of the client computing device and the server configured to:
• generate a brain state prediction for the user output using the trained brain model;
• and
• determine a feedback stimulus for the user from the brain state prediction using a feedback model, wherein the feedback model is associated with a target brain state;
• and
• the user effector configured to:
• provide the feedback stimulus to the user.
