<br></div>After standard pre-processing,I have adopted constant segmentation for each channel. The segment width is 1 second(256 samples) with 50 percent overlapping. I have calculated statistical parameters as mentioned above for these small segments. In this way I have tried to reduce the data dimensionality to some extent. But I am unable to form a feature vector that i can input to some standard classifier or clustering tool. <br>
<br></div>Please help with this problem. Please tell me whether my procedure is fine or I need to make some amendments. Above all please, help me form a feature vector that i can input into a classifier.<br></div>Hoping for a positive response.<br clear="all">
