The mission of the project is to share knowledge how to use machine learning in real life. Start to think how to get a business value for a given context. There’s a big gap, especially in Europe, how people think in the tech world. Usually, it’s more about technology or theory, and less about value and benefits. And one more gap is increasing demand for people who understand machine learning. DataWorkshop try to solve these problems. The idea is simple. Focus more on practical examples, less on theory (don’t try to cover all topics, only the most important). Explain by examples, not by theoretical formulas. Motivate to think and “feel” how to solve a problem, instead of memorizing some formulas or names (algorithms, models and so on). DataWorkshop accomplishes its goals through workshops, conferences, and courses.
