TUTORIAL - Mining and model understanding on medical data

 

KDD 2019, Anchorage - from August 04 to August 08

 

Tutorialists: Panagiotis Papapetrou (Stockholm) and Myra Spiliopoulou (Magdeburg)

Abstract

Medical research and patient caretaking are increasingly benefiting from advances in machine learning. The penetration of smart technologies and the Internet of Things give a further boost to initiatives for patient self-management and empowerment: new forms of health-relevant data become  available  and  require  new  data  acquisition  and  analytics’  workflows.  As  data complexity and model sophistication increase, model interpretability becomes mission-critical. But what constitutes model interpretation in the context of medical machine learning: what are the questions for which KDD should provide interpretable answers?

In  this  tutorial,  we  discuss  basic  forms  of  health-related  data Electronic  Health  Records, cohort data from population-based studies and clinical studies, mHealth recordings and data from  internet-based  studies.  We  elaborate  on  the  questions  that  medical  researchers  and clinicians pose on those data, and on the instruments they use giving some emphasis to the instruments “population-based study” and“Randomized Clinical Trial”.We elaborate on what questions are asked with those instruments, on whatquestions can be answered from those data,  on  ML  advances  and  achievements  on  such  data,  and  on  ways  of  responding  to  the medical experts’ questions about the derived models.

Target audience and prerequisites

This tutorial  is targeted to all  KDD  participants, with  particular  focus  group  being junior researchers  interested in machine for  health-related  data and on  how  to  convey  models  to experts. The main prerequisites for the participants concerns basic knowledge within the areas of data mining, machine learning, and databases. The audience is expected to be familiar with standard concepts and methods of machine learning. Such knowledge can be expected from KDD participants, including students.
