Entropy Journal2021Variational inference is a powerful framework, used to approximate intractable posteriors through variational distributions. The de facto standard is to rely on Gaussian variational families, which come with numerous advantages: they are easy to sample from, simple to parametrize, and many expectations are known in closed-form or readily computed by quadrature. In this paper, we view the Gaussian variational

Interspeech 2021 Workshop on Speech Synthesis (SSW11)2021Whilst recent neural text-to-speech (TTS) approaches produce high-quality speech, they typically require a large amount of recordings from the target speaker. In previous work [1], a 3-step method was proposed to generate high-quality TTS while greatly reducing the amount of data required for training. However, we have observed a ceiling effect in the level of naturalness achievable for highly expressive

KDD 2021 Workshop on Data-Efficient Machine Learning2021Intelligent Voice Assistant (IVA) systems, such as Alexa, Google Assistant and Siri, allow us to interact with them using just the voice commands. IVAs can elicit voice feedback directly from the users and use their responses to improve the various components of IVAs. One concern with using such crowdsourced voice feedback (CVF) data is the reliability of feedback itself such as background noise or disingenuous

KDD 2021 Workshop on Data-Efficient Machine Learning2021Automatically evaluating large scale dialogue systems’ response quality is a challenging task in dialogue research. Existing automated turn-level approaches train supervised models on Interaction Quality (IQ) labels or annotations provided by experts, which is costly and time-sensitive. Moreover, the small quantity of annotated data limits the trained model’s ability to generalize to the long tail and out

ICML 2021 Workshop on Distribution-Free Uncertainty Quantification2021Quantile regression is an effective technique to quantify uncertainty, and fit challenging underlying distributions. Generating full probabilistic predictions requires multiple quantile regressions over multiple quantile levels. As a result, quantile crossing is a common drawback to these approaches since it violates the desirable monotone property of the conditional quantile function. In this work, we
