• 論文抄録 / 内容記述: Recently, a Transformer-based partially trainable point process has been proposed, where a feature vector is extracted from past event sequence to predict the future event. However, high dependencies of the feature on last event and limitation of handmade designed hazard function would cause deterioration peformance. To overcome these problems, we propose a Transformer-based fully trainable point process, where multiple trainable vectors are embedded into the past event sequence and are transformed through an attention mechanism to realize adaptive and general approximation and prediction.We show the effectiveness of our proposed method through experiments on two datasets.
