I'm new at Artificial Neural Network and I'm using MATLAB;MATLAB developing Facial expression recognition and There are six expressions ; I'm not able to understand about How to create a target matrix? My Question is if I have SampleMatrix containing samples rowscolumns. While rows are the features and 29 columns represents a single sample I meant to say 29 columns belongs to the same class and If SampleMatrix dimensions are 21007174. 174 columns because I have 6 classes 6*29=179 What would the target matrix?
Kindly Help me out! Thanks.
