Data Sciences

Our Data Sciences team is responsible for building, governing, and maximizing the use of Target’s data assets for elevated decision-making across our retail operations. We build certified data sets for analytics and decision modeling and develop data platforms for exploration, visualization and measurement. We create statistical forecasting models, optimize algorithms with machine learning techniques, and validate model performance – with both analytical AI and generative AI – all while delivering algorithmic decisioning at massive scale. We empower our Target team with the insights they need to improve product and system performance and further innovate to improve guest experience.
