Online CP-Dictionary Learning Algorithm
Generalizes CP-decomposition for tensors, dictionary learning algorithm for vector-valued signals, and Online Nonnegative Matrix Factorization.

These codes are based on my paper below:

1. Christopher Strohmeier, Hanbaek Lyu, and Deanna Needell, “Online Dictionary Learning for Tensor Factorization” (submitted. Preprint available upon request.)

1. src/ocpdl.py : main Online CPDL algorithm implementation
2. src/BCD-DR.py : implementation for Alternatiing Least Squares and Multiplicative Update for NCPD. Original repo: https://github.com/HanbaekLyu/BCD-DR
3. OCPDL_benchmark.py : benchmark on NCPD against ALS and MU (generates benchmark figures in the paper)
4. image_reconstruction_OCPDL.py : Applicatoin codes for CP-dictionary learning for color images
5. video_reconstruction_OCPDL.py: Applicatoin codes for CP-dictionary learning for color videos
6. IMG_CP_reconstruction_main.py: Main script for image application (example run on Van Gogh's "Cafe terrace at night")
7. VIDEO_CP_reconstruction_main.py: Main script for video application (example run on mice brain activity video)
