Feedforward Nets for Interpolation and Classification
This paper deals with single-hidden-layer feedforward nets, studying various aspects of classification power and interpolation capability. In particular, a worst-case analysis shows that direct input to output connections in threshold nets double the recognition but not the interpolation power, while using sigmoids rather than thresholds allows doubling both. For other measures of classificatio...
متن کاملFault Tolerance of Feedforward Neural Nets for Classification Tasks
A method is proposed to estimate the fault tolerance of feedforward Artificial Neural Nets (ANNs) and synthesize robust nets. Fault models are presented and a procedure is developed to build fault tolerant ANNs by replicating the hidden units. Based on this procedure, metrics are devised t o quantify the fault tolerance aa a function of redundancy. A significant amount of redundancy is shown to...
متن کاملCapabilities and Training of Feedforward Nets
This paper surveys recent work by the author on learning and representational capabilities of feedforward nets. The learning results show that, among two possible variants of the so-called backpropagation training method for sigmoidal nets, both of which variants are used in practice, one is a better generalization of the older perceptron training algorithm than the other. The representation re...
متن کاملClustering in Weight Space of Feedforward Nets
We study symmetries of feedforward networks in terms of their corresponding groups and nd that these groups naturally act on and partition weight space. We specify an algorithm to generate representative weight vectors in a speciic fundamental domain. The analysis of the metric structure of the fundamental domain enables us to use the location information of weight vector estimates, e. g. for c...
متن کاملImage Interpolation using Feedforward Neural Network
As various kinds of output devices emerged, such as highresolution printers or a display of PDA(Personal Digital Assistant), the importance of high-quality resolution conversion has been increasing. This paper proposes a new method for enlarging image with high quality. One of the largest problems on image enlargement is the exaggeration of the jaggy edges. To remedy this problem, we propose a ...
