The Data Science accelerators are intense non-credit training courses given daily over 5 weeks. All accelerators include a theoretical component and a significant hands-on component, including in-class problem-solving using popular software packages on real-world data sets. All work is completed in the classroom. The accelerators are targeted to practitioners with diverse backgrounds who do not wish to pursue a formal degree program. The accelerators cover a wide range of topics, from refresher courses to theoretical and practical aspects of data science.
