Density-Informed VAE (DiVAE): Reliable Log-Prior Probability via Density Alignment Regularization
Michele Alessi, Alessio Ansuini, Alex Rodriguez
We introduce Density-Informed VAE (DiVAE), a lightweight, data-driven regularizer that aligns the VAE log-prior probability with a log-density estimated from data. St…

Unsupervised detection of semantic correlations in big data
Santiago Acevedo, Alex Rodriguez, Alessandro Laio
In real-world data, information is stored in extremely large feature vectors. These variables are typically correlated due to complex interactions involving many features simultane…
