Orange at GIS Ostrava

Ostrava is a city in the north-east of the Czech Republic and is the capital of the Moravian-Silesian Region. GIS Ostrava is a yearly conference organized by Jiří Horák and his team at the Technical University of Ostrava. University has a nice campus with a number of new developments. I have learned that this is the largest university campus in central and eastern Europe, as most of the universities, like mine, are city universities with buildings dispersed around the city.

Data Mining and Machine Learning for Economists

Last week Blaž, Marko and I held a week long introductory Data Mining and Machine Learning course at the Ljubljana Doctoral Summer School 2018. We got a room full of dedicated students and we embarked on a journey through standard and advanced machine learning techniques, all presented of course in Orange. We have covered a wide array of topics, from different clustering techniques (hierarchical clustering, k-means) to predictive models (logistic regression, naive Bayes, decision trees, random forests), regression and regularization, projections, text mining and image analytics.
