Machine translation is being revolutionized by the introduction of neural models. However, it is challenging to train high-quality neural translation models in small training data conditions, as usually, these models have lots of parameters.
In this talk, I give an overview of our research to tackle this problem from different angles using active learning (AL) and multitask learning (MTL) approaches. Firstly, our AL approach automatically learns an acquisition (policy) function in a Markov decision process formulation of the AL problem. Secondly, our MTL approach automatically learns a training schedule using a Markov decision process formulation of the problem.
