EEG data from concentrating ('true' data) automatically loads with the site. Press the "RELAXATION TEST DATA" button to switch over to a recording of EEG data while relaxing and vice versa to switch back.
To train a neural network that can classify (distinguish) concentration vs relaxation EEG data, press the "COLLECT TRUE DATA" button while the concentration EEG recording is playing. You will need at least 200 samples. Then switch to the relaxation data and press the "COLLECT FALSE DATA" button. Press the "TRAIN NEURAL NETWORK" button and then the "ACTIVATE NEURAL NETWORK" button.
Because this tool uses a simple MLP (Multi Layer Perceptron) neural network, the raw data signal won't work well under most settings. Switch all the nodes to "variance" before collecting data for fast results.
If you want to select specific EEG waves for analysis, just set all the nodes to that frequency band
