ICST 2020, IEEE Software2019Formal methods are mathematically based approaches for specifying, building, and reasoning about software. Despite 50 years of research and development, formal methods have had only limited impact in industry. While we have seen success in such domains as microprocessor design and aerospace (e.g., proofs of security properties for helicopter control systems1), we have not seen wide adoption of formal methods

DSAA 2019, IEEE DSAA 20192019Spoken language can include sensitive topics including profanity, insults, political and offensive speech. In order to engage in contextually appropriate conversations, it is essential for voice services such as Alexa, Google Assistant, Siri, etc. to detect sensitive topics in the conversations and react appropriately. A simple approach to detect sensitive topics is to use regular expression or keyword

Interspeech 20192019Named entity recognition (NER) is a vital task in spoken language understanding, which aims to identify mentions of named entities in text e.g., from transcribed speech. Existing neural models for NER rely mostly on dedicated word-level representations, which suffer from two main shortcomings. First, the vocabulary size is large, yielding large memory requirements and training time. Second, these models

International Journal of Semantic Computing2019We demonstrate the potential for using aligned bilingual word embeddings in developing an unsupervised method to evaluate machine translations without a need for parallel translation corpus or reference corpus. We explain different aspects of digital entertainment content subtitles. We share our experimental results for four languages pairs — English to French, German, Portuguese, Spanish — and present

NeurIPS 20192019We consider online forecasting problems for non-convex machine learning models. Forecasting introduces several challenges such as (i) frequent updates are necessary to deal with concept drift issues since the dynamics of the environment change overtime, and (ii) the state of the art models are non-convex models. We address these challenges with a novel regret framework. Standard regret measures commonly
