ACL-IJCNLP 20212021Large-scale conversational assistants like Alexa, Siri, Cortana and Google Assistant process every utterance using multiple models for domain, intent and named entity recognition. Given the decoupled nature of model development and large traffic volumes, it is extremely difficult to identify utterances processed erroneously by such systems. We address this challenge to detect domain classification errors

ICLR 2021 Workshop on Weakly Supervised Learning2021We have been witnessing the usefulness of conversational AI systems such as Siri and Alexa, directly impacting our daily lives. These systems normally rely on machine learning models evolving over time to provide quality user experience. However, the development and improvement of the models are challenging because they need to support both high (head) and low (tail) usage scenarios, requiring fine-grained

COMPSAC 2021 Workshop on DDS-BDAF2021Credit ratings are traditionally generated using models that use financial statement data and market data, which is tabular (numeric and categorical). Practitioner and academic models do not include text data. Using an automated approach to combine long-form text from SEC filings with the tabular data, we show how multimodal machine learning using stack ensembling and bagging can generate more accurate

CAV 20212021Over the past ten years, the adoption of cloud services has grown rapidly, leading to the introduction of automated deployment tools to address the scale and complexity of the infrastructure companies and users deploy. Without the aid of automation, ensuring the security of an ever-increasing number of deployments becomes more and more challenging. To the best of our knowledge, no formal automated technique

The Journal of Financial Data Science2021We present a machine learning pipeline for fairness-aware machine learning (FAML) in finance that encompasses metrics for fairness (and accuracy). Whereas accuracy metrics are well understood and the principal ones used frequently, there is no consensus as to which of several available measures for fairness should be used in a generic manner in the financial services industry. We explore these measures
