Data modeling lkm.fri.uni-lj.si Data model Different types of data from different sources Data mining Background knowledge
lkm.fri.uni-lj.si Models and their use Supervised and unsupervised modeling Model types: –decision trees and decision rules –artificial neural networks –regression trees –nearest neighbors –association rules –random forests –… Different models, different use: –model structure (presentation of the relationship between inputs and outputs) –prediction –associations (relationships) between input values –clustering –outlier detection –…
Example: applications in medical diagnostics and prognostics lkm.fri.uni-lj.si modeling the knowledge and skills of specialist physicians using models for decision support scintigraphy of the skeleton and heart, oncology, traumatology, …
Medical diagnostics and prognostics Input: background knowledge, descriptions of patients with subsequently confirmed diagnosis How to diagnose? How to predict the occurrence of a disease or its recurrence? Very good results in specialized areas (significantly better than specialists). What characteristics have the greatest impact on the disease? What is the reliability of computer predictions (diagnosis and prognosis)? How to explain predictions and bring them closer to doctors? lkm.fri.uni-lj.si
Reliability estimation for medical diagnosis General methods for estimating the reliability of individual predictions are developed.
Diagnosis explanation lkm.fri.uni-lj.si General methods for explaining predictions are developed.
lkm.fri.uni-lj.si Skeletal pathology detection Skeletal scintigraphy Background knowledge of human anatomy Known diagnoses
lkm.fri.uni-lj.si Diagnosis of coronary artery disease Heart scintigraphy Input data in the form of images Medical records Reliability estimates
Marketing How do customers decide what products to buy? How to arrange ads in an optimal way? When is the best time to broadcast television ads? lkm.fri.uni-lj.si
Advanced sports analysis lkm.fri.uni-lj.si in collaboration with the Faculty of Sport in Ljubljana : –analysis of the impact of rules changes in 2010/11 season A basketball match simulation
lkm.fri.uni-lj.si Versatile applicability of artificial intelligence methods, especially data mining –ability to process large amounts of data –variety of data types –inclusion of background knowledge However: Artificial Intelligence (still) is not intelligence Conclusion
