Data minimalism & data value by Michaela Regneri


Data is “the new oil” or “the new gold”. In the context of AI systems, we often treat Data more like “the new bacon”: Bigger data is better data, and we overfeed AI systems with data as a cheap, infinitely available resource.

We want to fight data’s bacon-like image by promoting the concept of data minimalism for AI as a strategy to enhance both, quality and sustainability of AI systems. In order to survive as data minimalists, we compute the (monetary) value of single data points, and then try to just keep the valuable ones.

Implementing this concept is as challenging and as interesting as it sounds. As a corporate-scale example, we show how much data actually is wasted in an e-commerce recommender system, and how we also found toxic data while applying our data-minimalization strategies.

Topic was presented at a joint event of Munich Datageeks and Women in Big Data Munich
