SIGIR 20192019Most real-world recommender services measure their performance based on the top-N results shown to the end users. Thus, advances in top-N recommendation have far-ranging consequences in practical applications. In this paper, we present a novel method, called Collaborative Denoising Auto-Encoder (CDAE), for top-N recommendation that utilizes the idea of Denoising Auto-Encoders. We demonstrate that the proposed

Interspeech 20192019In this paper, we extend our previous work on device-directed utterance detection, which aims to distinguish voice queries in-tended for a smart-home device from background speech. The task can be phrased as a binary utterance-level classification problem that we approach with a DNN-LSTM model using acoustic features and features from the automatic speech recognition (ASR) decoder as input. In this work

ICML 2019 Workshop on Time Series2019When forecasting time series with a hierarchical structure, the existing state of the art is to forecast each time series independently, and, in a post-treatment step, to reconcile the time series in away that respects the hierarchy (Hyndman et al.,2011; Wickramasuriya et al., 2018). We propose a new loss function that can be incorporated into any maximum-likelihood objective with hierarchical data, resulting

Interspeech 20192019Environmental sound classification systems often do not per-form robustly across different sound classification tasks and audio signals of varying temporal structures. We introduce a multi-stream convolutional neural network with temporal attention that addresses these problems. The network relies on three input streams consisting of raw audio and spectral features and utilizes a temporal attention function

EMNLP 20192019Natural Language Understanding (NLU) is a core component of dialog systems. It typically involves two tasks - intent classification(IC) and slot labeling (SL), which are then followed by a dialogue management (DM) component. Such NLU systems cater to utterances in isolation, thus pushing the problem of con-text management to DM. However, contextual information is critical to the correct prediction of intents
