Despite some similarities that have been pointed out in the literature, the parallelism between automated planning and natural language processing has not been fully analysed yet.

In particular, we study how a BERT model trained on plans computed for three well-known planning domains is able to understand how a domain works, its actions and how they are related to each other. In order to do that, we designed a variation of the typical masked language modeling task which is used for the training of BERT, and two additional experiments into which, given a sequence of consecutive actions, the model has to predict what the agent did previously (Previous Action Prediction) and what it is going to do next (Next Action Prediction).

Abstract

Despite some similarities that have been pointed out in the literature, the parallelism between automated planning and natural language processing has not been fully analysed yet. However, the success of Transformer-based models and, more generally, deep learning techniques for NLP, could open interesting research lines also for automated planning. Therefore, in this work, we investigate whether these impressive results could be transferred to planning. In particular, we study how a BERT model trained on plans computed for three well-known planning domains is able to understand how a domain works, its actions and how they are related to each other. In order to do that, we designed a variation of the typical masked language modeling task which is used for the training of BERT, and two additional experiments into which, given a sequence of consecutive actions, the model has to predict what the agent did previously (Previous Action Prediction) and what it is going to do next (Next Action Prediction).
