The status of the loan is shown in the model_id column, where 1 identifies a defaulted loan and 2 identifies a paid loan. Rows with the same model id are used to train a single model. The use of two model ids ensures that two different models are trained. Also notice that the defaulted loans end with observed_id=7 and paid loans end with observed_id=8. The seq_vertex_id column provides the ordering of the symbols in the sequences.
