Hello, I’m wondering when I want to apply regularization to all the values of my embedding layer in TensorFlow should I use activity_regularization or embeddings_regularization and what’s the difference please?
thanks, in advance.
Hi Salma,
In TensorFlow, when you want to apply regularization to all the values of your embedding layer, you should use the embeddings_regularizer parameter. This parameter allows you to specify a regularization function that will be applied to the weights of the embedding layer.
On the other hand, the activity_regularizer parameter is typically used to apply regularization to the output of a layer, rather than the weights themselves. It’s used to penalize large activations in the layer’s output, rather than controlling the values of the weights directly.
So, to summarize:
- Use
embeddings_regularizerto apply regularization directly to the weights of the embedding layer. - Use
activity_regularizerto apply regularization to the output of a layer, which can indirectly affect the weights through the optimization process.
Happy learning,
Rosa

Dear Rosa,
thank you very much for your answer.
Just to be sure, for this loss function if U and V are my embedding layers, I only have to define the frobinuis norm myself and add it as an embedding or activity regularization?
Hi,
If the Frobenius norm term is applied to the embedding layers U and V, it would typically be considered as a form of embedding regularization.
Embedding regularization involves applying constraints or penalties directly to the parameters of embedding layers, such as weights or embeddings, to prevent overfitting and encourage generalization. The Frobenius norm term, when applied to the parameters of the embedding layers, acts as a regularization term by penalizing the magnitudes or complexity of the embeddings themselves.
Hope that helps.
Best
Rosa
