Teacher:In this task, you will be presented with a context from an academic paper and you have to write an answerable question based on the context. Your questions can be extractive, abstractive, or yes-no questions.
Teacher: Now, understand the problem? Solve this instance: While $eta $-VAE offers regularizing the ELBO via an additional coefficient $eta \in {
m I\!R}^+$, a simple extension BIBREF16 of its objective function incorporates an additional hyperparameter $C$ to explicitly control the magnitude of the KL term,

where $C\!\! \in \!\! {
m I\!R}^+$ and $| . |$ denotes the absolute value.
Student:
How does explicit constraint on the KL divergence term that authors propose looks like?
