Abstract: Structured data is everywhere across enterprises and industries delivering significant business value by powering insights and actions derived through machine learning. Structured data comes in several forms and levels of complexity, like Flat tabular data (e.g. customer profile, dimension tables), Time series data (e.g. weekly sales, monthly promotional activity, instrument telemetry), Panel data (e.g. customer responses over time, geographic media spend) and Transactional data (e.g. administrative claims, EHR, website click stream) to name a few. Along with significant utility, there are also several challenges associated with this data that require companies to invest heavily to address, like partial data capture, missing values, rare occurrence of events of interest, limited labelled data, small data, etc. Data scientists have to come up with several custom pipeline adjustments iteratively to address these problems which is both time consuming, tedious and error prone. Generative Adversarial Networks (GANs) have had a lot of success in addressing these challenges for unstructured data but their application for structured data has been less explored. With the recent developments of its application for tabular data, GANs can act as a scalable approach to address these issues. In this session, we show how GANs can be used to augment structured data and thereby improve the structured data machine learning processes across datasets and domains. Examples include tasks like imputing missing data, over-sampling minority class for imbalanced data, creating synthetic data to improve training data and semi-supervized learning to leverage unlabeled data.
