Before revision:  In this paper, we present a mixture of experts model for predicting brain activity patterns . Given a new stimulus, the model predicts the entire brain activation as a weighted linear combination of activation of multiple experts .
After revision:  In this paper, we achieve this by clustering similar regions together and for every cluster we learn a different linear regression model using a mixture of linear experts model. The key idea here is that each linear expert captures the behaviour of similar brain regions . Given a new stimulus, the model predicts the entire brain activation as a weighted linear combination of activation of multiple experts .
