Online updating regularized kernel
Such segmentation is essential for studying anatomical structure changes and brain quantification .It is also a prerequisite for tumor growth modeling as tumors diffuse at different rates according to the surrounding tissues .A purely online model in this category would learn based on just the new input and some extra stored information (which is usually expected to have storage requirements independent of training data size).For many formulations, for example nonlinear kernel methods, true online learning is not possible, though a form of hybrid online learning with recursive algorithms can be used where .The algorithms have been validated against both synthetic and clinical magnetic resonance images with different types and levels of noises and compared with 6 recent soft clustering algorithms.Experimental results show that the proposed algorithms are superior in preserving image details and segmentation accuracy while maintaining a low computational complexity.IEEE Transactions on Pattern Analysis and Machine Intelligence 3D Face Recognition Using Simulated Annealing and the Surface Interpenetration Measure Queirolo, C.

This problem is tackled by incremental learning approaches.
Discriminant analysis is also different from factor analysis in that it is not an interdependence technique: a distinction between independent variables and dependent variables (also called criterion variables) must be made.
LDA works when the measurements made on independent variables for each observation are continuous quantities.
is a space of functions called a hypothesis space, so that some notion of total loss is minimised.
Depending on the type of model (statistical or adversarial), one can devise different notions of loss, which lead to different learning algorithms.
