 **Abstract**:​ In recent years, machine learning, and in particular deep learning, have made tremendous progresses both on theoretical and practical levels. Currently, machine learning algorithms are used by wide groups of practitioners,​ ranging from computer scientists, researchers in other exact science branches, technical people in data-intensive industries, and the grand public. However, with its successes, machine learning also has an Achille'​s heel: The operation of its algorithms is often opaque, and thus hard to understand, predict, and fine-tune. This raises serious problems for the effectiveness,​ replicability,​ trustworthiness,​ and ultimately applicability of machine learning in practical problems. **Abstract**:​ In recent years, machine learning, and in particular deep learning, have made tremendous progresses both on theoretical and practical levels.

 In this talk, we will discuss a broad range of techniques from information visualization and visual analytics that can be used to open this black box of machine learning for its interested users. Thereby, the general operation, unstable cases, learning behavior, and potential challenges encountered by machine learning techniques become visible, controllable,​ and actionable upon by its users. We will address questions such as: How to quickly determine if a classification problem is hard? How to understand what a neural network has learned (or not)? How to see which parts of some input data made a neural network take a given decision? And, above all, why do we need to understand deep learning black boxes for our businesses? Examples from real-world usage of visual analytics to help machine learning are presented coming from multiple application domains (image analysis, medicine, software engineering,​ and physics). In this talk, we will discuss a broad range of techniques from information visualization and visual analytics that can be used to open this black box of machine learning for its interested users.
