Losses

The losses.py module implements several common loss functions, including:

• Squared error
• Cross-entropy
• Variational lower-bound for binary VAE (Kingma & Welling, 2014)
• WGAN-GP loss for generator and critic (Gulrajani et al., 2017)
• Noise contrastive estimation (NCE) loss (Gutmann & Hyvärinen, 2010; Minh & Teh, 2012)
