VLDB Technology Conference on Performance Evaluation and Benchmarking 20192019With their capability to recognize complex patterns in data, deep learning models are rapidly becoming the most prominent set of tools for a broad range of data science tasks from image classification to natural language processing. This trend is supplemented by the availability of deep learning software platforms and modern hardware environments. We propose a declarative benchmarking framework to evaluate

Interspeech 20192019Recent works on end-to-end trainable neural network based approaches have demonstrated state-of-the-art results on dialogue state tracking. The best performing approaches estimate a probability distribution over all possible slot values. However, these approaches do not scale for large value sets commonly present in real-life applications and are not ideal for tracking slot values that were not observed

NeurIPS 20192019Despite the recent progress in hyperparameter optimization (HPO), available benchmarks that resemble real-world scenarios usually consist of a few and very large problem instances that are expensive to solve. This blocks researchers and practitioners from systematically running large-scale comparisons that are needed to draw statistically significant results. This work proposes a method to alleviate these

SiPS 20192019The Audio Front-End (AFE) is a key component in mitigating acoustic environmental challenges for far-field automatic speech recognition (ASR) on Amazon Echo family of products. A critical component of the AFE is the Beam Selector, which identifies which beam points to the target user. In this paper, we proposed a new SIR beam selector that utilizes subband-based signal-to-interference ratios to learn the

arXiv2019With the exploding growth of videos, there is an increasing interests for automatic video understanding. Video Story Question Answering (VSQA) proves to be an effective way for benchmarking the comprehension ability of a model. Recent VSQA approaches merely extract visual features from the whole scene or detected objects in each frame. However, it is hard to claim a method really understands a video without
