how can I build an attribute matrix

[alisadra]

in your code used binary PredicateMatrix which is a 1855-element vector that represent feature of each class. I used a specific CNN as a face feature extractor to obtain a 4096-element feature vector for each person(like your data).
So, how can I build an attribute matrix (PredicateMatrix in your code)? you can share code?

They are ordinary matlab variables. The column and row correspond to the categories and their associated semantic vectors, respectively. Saving the values to the variables should do the job.
