Abstract
Techniques for multi-layer training of a machine learning model are disclosed. A system pre-trains a machine learning model on training data obtained from unlabeled document graph data by executing unsupervised pre-training tasks on the unlabeled document graph data to generate a labeled pre-training data set. The system modifies document graphs to change attributes of nodes in the document graphs. The system pre-trains the machine learning model with a data set including the modified document graphs and un-modified document graphs to generate prediction associated with the modifications to the document graphs. Subsequent to pre-training, the system fine-tunes the machine learning model with a set of labeled training data to generate predictions associated with a specific attribute of a document graph.
