Problem description
My first question is related to the paper here. In the section 4.5 (TVAE model), you mention that the model outputs a joint distribution of 2Nc + Nd variables. you also mention in the equation (attached below) about two variables αbar i,j and αhat i,j. Can you please explain these a bit and also about the combined distribution (last line in the equation)?

I have observed that I cannot change the activation function in the TVAESynthesizer. Below is the snippet for the model params I could change (mentioned in sdv docs using
synthesizer.get_parameters()
).synthesizer.get_loss_values()
gives only the total loss, Is there a way I can track the reconstruction_loss and kl_loss separately?I hope my questions are clear.
Thanks in advance!
