The classifiers accuracy can never be 100%. The classifiers gets trained on training set and then work on the data. Porbably you should make your training set richer or mark that as an error.

Hi Harshit I know that the classifier accuracy can never be 100% but my problem is when I've applied this function to some signal the accuracy is 0 %. I've obtained just the opposite of the real value.
