WSDM 20202020Accurately learning from user data while providing quantifiable privacy guarantees provides an opportunity to build better ML models while maintaining user trust. This paper presents a formal approach to carrying out privacy preserving text perturbation using the notion of dχ-privacy designed to achieve geo-indistinguishability in location data. Our approach applies carefully calibrated noise to vector

ASRU 2019, ICASSP 20202019Most recent neural semi-supervised learning algorithms rely on adding small perturbations to either the input vectors or their representations. These methods have been successful on computer vision tasks, as the images form a continuous manifold, but they are not appropriate for discrete inputs such as sentences. To adapt these methods to text input, we propose to decompose a neural network M into two components

ASRU 20192019Building conversational speech recognition systems for new languages is constrained by the availability of utterances capturing user-device interactions. Data collection is expensive and limited by speed of manual transcription. In order to address this, we advocate the use of neural machine translation as a data augmentation technique for bootstrapping language models. Machine translation (MT) offers a

NeurIPS 2019 Workshop on Conversational AI2019Many businesses and consumers are extending the capabilities of voice-based services such as Amazon Alexa, Google Home, Microsoft Cortana, and Apple Siri to create custom voice experiences (also known as skills). As the number of these experiences increases, a key problem is the discovery of skills that can be used to address a user’s request. In this paper, we focus on conversational skill discovery and

NeurIPS 2019 Workshop on Bayesian Learning2019Search engine performance is usually good on head (high-frequency) queries due to the rich availability of historical behavioral signals on these queries. An over-reliance on past behavioral signals can potentially impact the performance on the tail (low-frequency) queries, where there is a lack of behavioral data. One way to address this issue is to reformulate a tail query into an appropriate head query
