Application-driven Intersections between Information Theory and Machine Learning
… encoder and a maximize a posterior (MAP) decoder, our scheme significantly outperforms existing schemes in reducing the false negative rate of rare bio-molecular types. In the third part, we exercise guesswork on the machine translation problem. We study machine translation using the …
