ICSE 20202020This experience report describes a style of applying symbolic model checking developed over the course of four years at Amazon Web Services (AWS). Lessons learned are drawn from proving properties of numerous C-based systems, e.g., custom hypervisors, encryption code, boot loaders, and an IoT operating system. Using our methodology, we find that we can prove the correctness of industrial low-level C-based

ICASSP 20202020We propose a novel approach to semi-supervised automatic speech recognition (ASR). We first exploit a large amount of unlabeled audio data via representation learning, where we reconstruct a temporal slice of filter bank features from past and future context frames. The resulting deep contextualized acoustic representations (DeCoAR) are then used to train a CTC-based end-to-end ASR system using a smaller

ESANN 20202020Developing learning methods which do not discriminate sub-groups in the population is the central goal of algorithmic fairness. One way to reach this goal is to learn a data representation that is expressive enough to describe the data and fair enough to remove the possibility to discriminate subgroups when a model is learned leveraging on the learned representation. This problem is even more challenging

MLSys 2020 Workshop on MLOps Systems2020Machine learning (ML) has become a central component in modern software applications, giving rise to many new challenges [8, 15, 20]. Tremendous progress has been made in this context with respect to model serving [1, 6, 10], experiment tracking [14, 16, 22, 23], model diagnosis [4, 5, 11, 21] and data validation [4, 18]. In this paper, we focus on the arising challenge of automating the operation of deployed

AISTATS 20202020Multiple hypothesis testing, a situation when we wish to consider many hypotheses, is a core problem in statistical inference that arises in almost every scientific field. In this setting, controlling the false discovery rate (FDR), which is the expected proportion of type I error, is an important challenge for making meaningful inferences. In this paper, we consider a setting where an ordered (possibly
