Abstract: A model learning and sample value generating framework includes a system and method to comprehensively integrate encoding, decoding and value predicting, and optimizing functions to reconstruct as accurate as possible an original input sample data space. The system leverages a variational autoencoder model to generate as realistic samples of that data space as possible. The system learns a value prediction function to achieve a target outcome based on the latent feature data instead of the original input data. Further, the system solves the optimization problem in the latent space without constraints to avoid the difficulty in optimizing in the original sample data space. The generated optimal samples are as similar as possible to the real-world input samples. The system provides a flexible data generation mechanism which is suitable for various kinds of target outcome specifications.
