1. FM algorithm
FM (Factor Machine, factoring machine) is a machine learning algorithm matrix decomposition algorithm based on the combination of features in order to solve the problem of large-scale sparse data. FM algorithm is recommended areas have been verified one better recommendation algorithm, widely used in the field of electric recommendation, advertising, broadcast and so on.
2. FM Advantage algorithm
Combination of features: twenty-two characterized by a combination of introducing cross-terms.
Solve the curse of dimensionality: Hidden by introducing a vector to achieve the characteristic parameter estimation.
3. FM expression
