A hybrid feature selection strategy for image defining features: towards interpretation of optic nerve images

Yu, Abidi, Artes
2005 2005 International Conference on Machine Learning and Cybernetics  
We present our approach that involves the analysis of CSLT images using moment methods to derive abstract image defining features, and then the use of these features to train classifiers for automatically  ...  distinguishing CSLT images of healthy and diseased optic nerves.  ...  The rationale for feature subset selection is based on the observation that a large number of abstract moments tend to compromise the accuracy of supervised learning classifiers, the classification rules  ...

Delusions and the Role of Beliefs in Perceptual Inference

K. Schmack, A. Gomez-Carrillo de Castro, M. Rothkirch, M. Sekutowicz, H. Rossler, J.-D. Haynes, A. Heinz, P. Petrovic, P. Sterzer
2013 Journal of Neuroscience  
In a combined behavioral and functional neuroimaging study in healthy participants, we used ambiguous visual stimulation to probe the relationship between delusion-proneness and the effect of learned predictions  ...  Delusions are unfounded yet tenacious beliefs and a symptom of psychotic disorder. Varying degrees of delusional ideation are also found in the healthy population.  ...  The arithmetic mean of the two classspecific accuracies gave the balanced prediction accuracy.  ...
