Abstract:


We consider the task of learning a reverse dictionary -- retrieve words that evoke a specific concept. The current state of the art computational models for this are based on recurrent neural networks. In this paper, we significantly push the state of art on this task by introducing a new model based on transformer blocks along with a custom loss function based on feedback from attention scores. We empirically show that our model significantly outperforms the current state of the art by 8 points on the standard metric of median rank.
