Mini Course on Medical Decision Support:
From Data Science to Explainable AIpierre-simon-de-laplace-machine-learning

“It is remarkable that a science which began with the consideration of games of
chance should have become the most important object of human knowledge”
Pierre Simon de Laplace, 1812.

Winter Term 2019 (next lecture: September, 2019 Vienna, 3 ECTS at the WU Executive Academy)

Short Description: This Mini-Course is an introduction into a core area of health informatics and helps to understand decision making generally and how human intelligence can be augmented by Artificial Intelligence (AI) and Machine Learning (ML) specifically (-> What is the difference between AI/ML?). Andreas Holzinger has taught this course in various versions, variations and  duration since 2005.

Module 00 – Primer on Probability and Information (optional)

When confronted with decision making we inherently must deal with our world of uncertainty. The strenght of probabilistic machine learning results from the mathematically thus computationally mechanisms of the combination of prior knowlege with incoming new data.

Topic 00: Mathematical Notations
Topic 01: Probability Distribution and Probability Density
Topic 02: Expectation and Expected Utility Theory
Topic 03: Joint Probability and Conditional Probability
Topic 04: Independent and Identically Distributed Data (IIDD)
Topic 05: Bayes and Laplace
Topic 06: Measuring Information: Kullback-Leibler Divergence and Entropy

Practical Work: Planning a 500-bed hospital IT-infrastrucure –
how to bring AI/ML directly into the clincial workflow

In a roleplay groupwork the task is to optimize clinical/medical workflows with AI/Machine Learning tools,
for decision support and quality enhancement. A strong issue is to consider social, ethical and legal aspects
and to enable accoutable, interpretable, replicable and ethical responsible AI enhancements, fostering security, safety and trust.

About the Lecturer:

Andreas Holzinger promotes a synergistic approach to Human-Centred AI (HCAI) and has pioneered in interactive machine learning (iML) with the human-in-the-loop. He promotes an integrated machine learning approach with the goal to augment human intelligence with artificial intelligence to help to solve problems in health informatics.

Due to raising ethical, social and legal issues governed by the European Union, future AI supported systems must be made transparent, re-traceable, thus human interpretable. Andreas’ aim is to explain why a machine decision has been reached, paving the way towards explainable AI and Causability, ultimately fostering ethical responsible machine learning, trust and acceptance for AI.

Andreas obtained a Ph.D. in Cognitive Science from Graz University in 1998 and his Habilitation (second Ph.D.) in Computer Science from Graz University of Technology in 2003. Andreas was Visiting Professor for Machine Learning & Knowledge Extraction in Verona, RWTH Aachen, University College London and Middlesex University London. Since 2016 Andreas is Visiting Professor for Machine Learning in Health Informatics at the Faculty of Informatics at Vienna University of Technology. Currently, Andreas is Visiting Professor for explainable AI, Alberta Machine Intelligence Institute, University of Alberta, Canada.

Andreas Holzinger is lead of the Holzinger Group (HCAI-Lab), Institute for Medical Informatics/Statistics at the Medical University Graz, and Associate Professor of Applied Computer Science at the Faculty of Computer Science and Biomedical Engineering at Graz University of Technology. He serves as consultant for the Canadian, US, UK, Swiss, French, Italian and Dutch governments, for the German Excellence Initiative, and as national expert in the European Commission. His is in the advisory board of the Artificial Intelligence Strategy AI made in Germany  of the German Federal Government and in the advisory board of the Artificial Intelligence Mission Austria 2030.
