Latent space

As explained in Machine Learning for Tabular Data: XGBoost, Deep Learning, and AI

A latent space is a lower-dimensional representation space in which a model encodes condensed information about observed data.

A latent space is a lower-dimensional representation where an encoder stores highly condensed information about observed data. In a variational autoencoder, a decoder expands that representation and reconstructs the original input. When compression and reconstruction work well, the latent space captures core distributional information that can support generating new data. section 2.3.3

Synthetic tabular data

A tabular workflow can fit SDV's TVAESynthesizer to the 1,000-row German Credit Risk dataset and sample 10,000 additional synthetic rows. The latent representation is the compressed intermediate state behind this generation process. section 2.3.3

How Machine Learning for Tabular Data: XGBoost, Deep Learning, and AI covers it

How deep it goes
Defines encoder-decoder flow and distributional purpose, but stops short of latent-variable mathematics or detailed training mechanics.
Examples
Uses German Credit Risk data and SDV's TVAESynthesizer to generate 10,000 synthetic examples.
What you can do after
Apply it via SDV's TVAESynthesizer to fit tabular data and sample synthetic rows.
How it connects
Connects variational autoencoders, encoders, decoders, reconstruction, data compression, and synthetic data generation.
