The importance of Data Quality in AI

Dr. Sahar Changuel from Société Générale has a PhD in machine learning and Natural Language Processing (NLP) and during the last 10 years of experience she didn’t stop working with data in its different format, structured and unstructured.

Today she is a Senior Data Manager and a Data Quality Manager. Her objective is to promote the data quality in her department, and to put in place a framework to remediate data quality issues.

At the DATA festival in May 2022 she gave a live presentation on “How to tackle Data Quality issues“. In it she adresses, amongst others, the impact of poor quality data on machine learning prediction results. Before her presentation, she gave Judith a backstage interview.
