Some persistent problems existing for classical neural nets (such as multilayer perceptrons) local minima and choice of the number of hidden units. To a large extent these problems are avoided in SVMs. brain surgeon) 1] 10] [13] involves computing a Hessian matrix or its inverse, in LS SVMs all necessary pruning information follows from the solution vector itself. The second potential drawback is circumvented by applying a weighted least squares version. In this way, the solution can be easily robustified in order to ....
....sparseness can be imposed to LS SVMs by a pruning procedure which is based upon the sorted support value spectrum. This is important in view of an equivalence between SVMs and sparse approximation, shown in [8] An important difference with pruning methods in classical neural networks [1] 10] [13], e.g. optimal brain damage and optimal brain surgeon, is that the LS SVM pruning procedure requires no computation of a Hessian matrix. One immediately gets all necessary pruning information from the solution to the linear system itself. Hence, by plotting the spectrum of the sorted j k j values ....

....training process is the architecture synthesis. An architecturally optimized network supplies structural information about the input field as used by the model, thus giving a qualitative measure of importance. The output of our new procedure is a map quantifying the importance (saliency c.f. [7]) of each individual component of the measurement (i.e. pin, pixel, or voxel) with respect to the obtained empirical relation. Hopefully, this so called saliency map will assist the modeler in interpreting the model and in communicating the interpretation to the end user. In bio medical context it ....
....and data reduction in order to bring down the dimensionality of the neural network. However, we have recently shown that one may cure this extremely ill posed problem using straightforward linear algebra without loss of information [2] 5] The scheme achieves massive weight sharing [7] by projecting the high dimensional data onto a low dimensional basis spanning the so called signal space of the training set input vectors. The saliency map is an attempt to visualize this induced geometry and the specific manner in which this geometry is used by the trained network. As a ....

Methods for network growing (such as Cascade Correlation [5] and for network pruning (such as Optimal Brain Damage [16]) have been used to overcome the long process for determining a good network architecture.

EVOLUTION OF ARTIFICIAL NEURAL NETWORKS Various methods have been suggested for the automatic construction of ANN topologies. Among these are Network Growing (OBS [8] OBD [9], etc. Network Pruning (Cascade Correlation [10] etc. and Evolutionary Design of networks.
