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

ICASSP 20192019This paper presents our work of training acoustic event detection (AED) models using unlabeled dataset. Recent acoustic event detectors are based on large-scale neural networks, which are typically trained with huge amounts of labeled data. Labels for acoustic events are expensive to obtain, and relevant acoustic event audios can be limited, especially for rare events. In this paper we leverage an Internet-scale

AISTATS 20202019We study the problem of offline learning in automated decision systems under the contextual bandits model. We are given logged historical data consisting of contexts, (randomized) actions, and (nonnegative) rewards. A common goal is to evaluate what would happen if different actions were taken in the same contexts, so as to optimize the action policies accordingly. The typical approach to this problem,
