each 0.5s. Each trial had about 270,000 voxels. The data was differentiated into 25 ROA or Regions of
Activation. These data were used to find out the feasibility of our SVM and LR classifiers.

6.3.3 RESULT EVALUATION
A simple evaluation method is a train test dataset where the dataset is divided into a train and a test
dataset, then the learning model is trained using the train data and performance is measured using
the test data. In a more sophisticated approach, the entire dataset is used to train and test a given model.
