I have made one channel EEG setup using ADS1299 which is controlled by using R programming software. I have taken dataset for Concentration and relaxation for approx. 5 min each. Data has been trained using SVM in R and result is 0.03 % error. The problem is system is showing only relaxation everytime as a result for rumtime environment. Can somebody guide me how to test whether my training data is efficient or not?. Suggestion for EEG classification problem are also requested.
