COLLABORATIVE DEEP LEARNING

Novel approach combining Deep Learning with Collaborative Filtering for Recommender Systems. Experiments with research paper: Collaborative Deep Learning for Recommender Systems. The original code has been taken from the paper and adapted for a course project.

#Usage Notes First run cdl.py. In this code relu activation has been used instead of sigmoid and the code does not use pretraining

Evaluate

To evaluate run evaluate_CDL.py. The code calculates recall@M for M from M_low to M_high. Keep the value of variable "p" same as in cdl.py. This "p" is used for the directory path for model files generated, not to be conufsed with "P" used to denote the sparse (P=1) and dense(P=10) settings.
