Why Stateless Synthetic Data Fails at Complex Business Logic
(CausalFoundry Track) Modern enterprise systems are highly stateful. A user adds an item to a cart, proceeds to checkout, pays, and an item is shipped. This is...
GANs vs. Deterministic Synthetic Data for ML Training
If you ask a Generative Adversarial Network (GAN) or a Variational Autoencoder (VAE) to generate a million rows of synthetic financial transactions, the output...
