This is the demo code for paper "Tensor Train Neighborhood Preserving Embedding"
Copyright @ Wenqi Wang, 2018
To run the experiment Fig.3 and Fig.6 of the paper Tensor Train Neighborhood Preserving Embedding
(1) Data processing: download Weizmann Dataset from http://www.wisdom.weizmann.ac.il/~/vision/FaceBase/ and build a tensor named 'Data' with dimension 512 x 352 x 66 x 17, which represents 66 images of size 512 x 352 from 17 persons. Save it with name 'WeizmanData.mat' and put it in the folder Data_file.
(1) run demo.m for NPE algortihm comparision among KNN, TNPE and TTNPE
(2) The TTNPE-ATN is the implemented in the code Self_Tool/main_App.m. Please refer this function and the folder TT_Approximate for the detail implementation of the algorithm.
