[Dependencies]

CP tensor factorization Toolbox :

This function needs the CP tensor factorization toolbox (default is cp3_alsls)

SVM solver:

Libsvm toolbox (default is libsvm-3.17)

[Table of Contents]

Main.m : demonstrate the algorithms on a CP factorization dataset and show the usages

Divide.m : Divide the data into k-fold

TrainAverAcc.m : train optimal support higher-order tensor machine with DuSK kernel

Ker_DuSK.m : calculate the DuSK kernel (RBF or linear).

[Dataset]

Data_ADNI.mat : the CP factorization result of ANDI dataset

You can factorize each dataset by cp3_alsls toolbox, like Data_ADNI
