Data Drift Identification for NLP Models in the Context of AI Governance for Enterprises

Abstract: 

Data drift is a crucial challenge for AI models dealing with Natural Language Processing like Named Entity Recognition. Lack of monitoring of Data drift for such NLP models, running in production, can potentially make the model unusable by the model consuming applications in enterprises. Also, lack of ability to monitoring important metric like Data drift can pose a big challenge to run the model in production from AI Governance perspective as it may be against the compliance standards. The Data drift can be identified in variety of ways; namely based on Lemma, Synonyms, Positions, Parts of Speech, or Context. However, from AI Governance perspective implementing the Data drift identification for AI Models deployed in Production is a challenge. The distribution of vectorized word corpus used in Model Development time need not be necessarily available during Model Monitoring time (when model is running in production) because of different contraints and challenged faced in an enterprise. The models may be developed in a different technology platform and monitored in other; there may be legal/compliance restriction in terms of sharing training data with POI information; the binary of corpus distribution may be too large to be shared; and many other similar challenges can make Data drift monitoring of such NLP models very difficult to implement. In this presentation, we shall cover the specific of these challenges in details in the context of enterprise implementation of such models running in production. We shall also cover a working solution addressing those challenges, with a case study of such NLP model in Financial industry, that can be used as a reference to address Data drift monitoring challenges for similar NLP models.
