You have historical intraday data for a universe of equities. Design features and a modeling approach to predict a target stock's volatility over the next 30 minutes after removing systematic market effects. Explain how you would:

define the prediction target,
engineer features from the stock itself,
use information from related stocks or sector peers,
choose an appropriate model and validation strategy for time-series data, and
if you use an autoencoder, decide the size of the latent bottleneck.
