Collaborative Filtering Tutorial Codes

Collaborative Filtering Tutorial Codes

The original codes comes from "Coursera Machine Learning" by prof. Andrew Ng, the program assignment of week 9.
I implemented this by Python,
1.Numpy + Scipy.Optimize
2.TensorFlow

  • ex8_cofi.py: Numpy + Scipy.Optimize code
  • check_costfun.py: support functions for ex8_cofi.py
  • cofi_tf.py: TensorFlow code
