Description Unfortunately, the predictive models that are most powerful are usually the least interpretable. However in some cases, for example fraud detection, end users need an understandable explanation of a particular prediction, at observation level, and not only at population level (e.g. : features importance). During this talk we will ...

Description What can Python-based software teams learn from aviation? Why should software always fail hard? What's wrong with too many error logs? And why are ops people already like pilots? Learn all this, and about planes, too.
Description scikit-image is a general-purpose image processing module for the Python programming language. It is designed to interact efficiently with other popular scientific Python libraries, such as NumPy and SciPy. In particular, scikit-image leverages the powerful data array container of NumPy, that can store images of various dimensions (2-D, 2D ...
Description Teacher, developer and consultant in a wide variety of business applications. Particularly interested in the field of very large databases, with special emphasis in squeezing the last drop of performance out of computer as whole, i.e. not only the CPU, but the memory and I/O subsystems.
Description Success in data science projects depends upon clean input data. Text data is often badly encoded, lacks data types and is inconsistent. Aimed at the intermediate Pythonista I’ll talk about the time saving tools I use in ModelInsight to clean and normalise my data so you can easily work ...
Description Descriptors and metaclasses are advanced Python features. While it is possible to write Python programs without active knowledge of them, knowing more about them facilitates a deeper understanding of the language. With examples, you will learn how they work and how to write your own descriptors and metaclasses. Furthermore, ...
