About regularization

[helenxu]

Hi,

From the code I see:

    # Regularization Parameters (start with no regularization)
    self.reg_0 = 0.0
    self.reg_w = 0.0
    self.reg_v = np.repeat(0.0, num_factors)

However, I don't see where the regularization parameters are updated. Moreover, after fitting the model, I used model.reg_v to output the regularization parameters, it gave me an array of zeros. I am wondering does the model impose regularization on the model parameters? Thanks

Hi,

I add arguments and activate the regularizations.
