Learning to Predict Explainable Plots for Neural Story Generation
Table 3: The results of ablation study. We use “PM” to denote the planning model, “SM” to denote the summarization model, and “PT” to denote pre-training.

Our approach reduces to Direct by removing the planning model. Note that the summarization model is also disabled in this case. Only discarding the summarization model leads to the worst results. This suggests that the summarization model is critical for improving the performance of our approach: it is difficult to learn a good planning model without the guidance of the summarization model. Besides, the performance of our method also drops without pre-training, which indicates the effectiveness of pre-training in our approach.
