ELBO maximization is equivalent to:
Answer options
A
Minimizing reconstruction only
B
Maximizing a lower bound on data likelihood
C
Training discriminator
D
Solving linear equations only
Correct answer: Maximizing a lower bound on data likelihood
Explanation
ELBO (Evidence Lower BOund) is the VAE training objective. Maximizing ELBO is equivalent to maximizing a lower bound on the data log-likelihood while regularizing the latent space.
