Matrix-Factorization-recommender-System

In this repository, I implement a recommender system using matrix factorization. Here, two types of RS are implemented. First, use the factorized matrix for user and item. and second, rebuild the Adjacency matrix. both approaches are acceptable and implemented in this repo. To factorized the matrix, funk-svd Algorithm is used. you can find his implementation on this link: https://github.com/gbolmier/funk-svd

Hidden-Markov-Model

In this Repository, Algorithms of learning HMM with two approaches is implemented: first, learn parameter when having observations and related state of them with Maximum Likelihood Alg. and the second approach in the condition that just have observations with forward-backward Alg. after constructing HMM Viterbi Alg. is implemented to test a sequence of observation.

Multilayer_Perceptron

In this Repo. a Multilayer Perceptron is implemented. Both Regression and Classification task is done on yearpredictionmsd dataset.
