Identifying the functional roles of elements of a neural network is one of the first challenges in understanding neural information processing. Aiming at this goal, lesion studies have been used in neuroscience, most of which employing single lesions and hence, limited in their ability to reveal...

The FIRST survey (Faint Images of the Radio Sky at Twenty-cm) is scheduled to cover 10,000 square degrees of the northern and southern galactic caps. Until recently, astronomers classified radio-emitting galaxies through a visual inspection of FIRST images. Besides being subjective, prone to...

An alternative model to class conditional probability estimation for classification problems is introduced. The model assumes a deterministic mapping between input space and the set of classes, training data consists of probability distributions of the classes at the measurements points. A...

This paper proposes a new architecture for neural networks where the hidden layer is completely replaced by what is referred to as a 'principal component layer'. This layer consists of only a few selected principal components that perform the function of hidden nodes. Then, an algorithm based on...

This paper presents a Hopfield neural network model for matching features invariant to projective transformation. The projective invariance has been firstly embedded into the compatibility constraint, such that the problem of finding point correspondences can be formulated as minimizing the...

It is well known that multilayer neural networks with generalized delta rule (GDR) can map any arbitrary functions. The relationship between statistical linear regression and network learning has been attributed to the principal components which can be extracted from the input patterns along....

This paper presents an algorithm of playing game tic-tac-toe. This algorithm is learned by a modified neural network (NN), which is trained by an improved genetic algorithm (GA). In the proposed NN, the neuron has two activation transfer functions and exhibits a node-to-node relationship in the...

A multilayer neural network with one hidden layer and with 1 hidden layer neurons can exactly implement an arbitrary training set with training patterns. It is only sufficient and not necessary to use -1 hidden neurons. For a particular training set, this number can be reduced. Here, monotone...
