1 Intelligent Database Systems Lab Presenter : CHANG, SHIH-JIE Authors : Andrés Ortiz, Juan M. Górriz, Javier Ramírez, F.J. Martínez-Murcia 2013.PRL LVQ-SVM based CAD tool applied to structural MRI for the diagnosis of the Alzheimer’s disease

2 Intelligent Database Systems Lab Outlines Motivation Objectives Methodology Experiments Conclusions Comments

3 Intelligent Database Systems Lab Motivation  The Alzheimer’s disease is at an advanced stage and there is no a known cure for the AD disease since currently.

4 Intelligent Database Systems Lab Objectives In order to deal with objective diagnosis of the AD, this paper use many techniques to diagnosis more effective better than before.
