NeurIPS 2019 Workshop on Machine Learning and Physical Sciences2019Decision making in uncertain scenarios is an ubiquitous challenge in real world systems. Tools to deal with this challenge include simulations to gather information and statistical emulation to quantify uncertainty. The machine learning community has developed a number of methods to facilitate decision making, but so far they are scattered in multiple different toolkits, and generally rely on a fixed backend

EMNLP 2019 Workshop on Machine Reading for Question Answering2019We present a system for answering questions based on the full text of books (BookQA), which first selects book passages given a question at hand, and then uses a memory network to reason and predict an answer. To improve generalization, we pretrain our memory network using artificial questions generated from book sentences. We experiment with the recently published NarrativeQA corpus, on the subset of Who

IWSLT 20192019We evaluate three simple, normalization-centric changes to improve Transformer training. First, we show that pre-norm residual connections (PRENORM) and smaller initializations enable warmup-free, validation-based training with large learning rates. Second, we propose `2 normalization with a single scale parameter (SCALENORM) for faster training and better performance. Finally, we reaffirm the effectiveness

CIKM 20192019Fact-centric information needs are rarely one-shot; users typically ask follow-up questions to explore a topic. In such a conversational setting, the user’s inputs are often incomplete, with entities or predicates left out, and ungrammatical phrases. This poses a huge challenge to question answering (QA) systems that typically rely on cues in full-fledged interrogative sentences. As a solution, we develop

Interspeech 20192019This paper proposes a simple phone mapping approach to multi-dialect acoustic modeling. In contrast to the widely used shared hidden layer (SHL) training approach (hidden layers are shared across dialects whereas output layers are kept separate), phone mapping simplifies model training and maintenance by allowing all the network parameters to be shared; it also simplifies online adaptation via HMM-based
