NN regularization term

Hi,
In the video “Deep Learning for content-based filtering” it is about “NN regularization term”
We have already seen cases of regularization but not in the context of neural networks (unless I am mistaken).
What type of regularization is it (L1 or L2 or?). Do you have a formula respecting the notations of this video?

Thanks,
Regards,
Pierre

Hello @Pierre_BEJIAN, it can be L1 or L2. Their formulae are exactly how they look before: for each weight w, \lambda |w| and \lambda w^2.
