Morphological Inflection Generation with Hard Monotonic Attention

Abstract

We present a neural model for morphological inflection generation which employs a hard attention mechanism, inspired by the nearly-monotonic alignment commonly found between the characters in a word and the characters in its inflection. We evaluate the model on three previously studied morphological inflection generation datasets and show that it provides state of the art results in various setups compared to previous neural and nonneural approaches. Finally we present an analysis of the continuous representations learned by both the hard and soft attention
