WebOct 30, 2024 · Here we train a graphical autoencoder to generate an efficient latent space representation of our candidate molecules in relation to other molecules in the set. This approach differs from traditional chemical techniques, which attempt to make a fingerprint system for all possible molecular structures instead of a specific set. WebWe can represent this as a graphical model: The graphical model representation of the model in the variational autoencoder. The latent variable z is a standard normal, and the data are drawn from p(x z). The …
