Abstract: Provided herein are improved methods for training graph neural networks (GNNs) to predict the binding affinity of novel compounds based on data generated from DNA-encoded library (DEL) experiments. These methods include training the GNN to predict affinity for the target directly and then applying the predicted affinity to a model of the DEL experiment process to generate a predicted DEL read count.

The loss value can then be used to update the GNN as part of a GNN training process. The loss value can be augmented with simulated disynthon data generated from the predicted affinity.
