Genetic Algorithm and Graph Theory Based Matrix Factorization Method for Online Friend Recommendation
Online friend recommendation is a fast developing topic in web mining. In this paper, we used SVD matrix factorization to model user and item feature vector and used stochastic gradient descent to amend parameter and improve accuracy. To tackle cold start problem and data sparsity, we used KNN model...
