Abstract
Sub-word level alternations during inflection (apophonies) are an common linguistic phenomenon present in morphologically-rich languages, like Romanian. Inflection learning, or predicting the inflection class of a partially regular or fully irregular verb or noun in such a language has been a widely studied task in NLP, but generative models are limited to capturing the most common ending patterns and apophonies. In this paper, we show how to train a character-level Recurrent Neural Network language model to be able to accurately generate the full inflection of verbs in Romanian, Finish, and Spanish and model stem-level phonological alternations triggered by inflection in an unsupervised way. We also introduce a method to evaluate the accuracy of the generated inflections.

Notes
- 1.
aiweirdness.com has used it extensively.
- 2.
Note this skip-connects 1) the embedding layer and 2) the first LSTM layer to the attention layer, which helps to alleviate vanishing gradients when the model is learning the weights of these first two layers.
