It is pointed out that the outputs of the output layer in the FNNs for classification correspond to the estimates of posteriori probability of the input pattern samples with desired outputs 1 or 0. The theorem for the generalized kernel function in the radial basis function networks (RBFN) is given. For an 2-layer perceptron network (2-LPN). an idea of using extended samples to improve generalization capability is proposed. Finally. the experimental results of radar target classification are given to verify the generaliztion capability of the RBFNs.展开更多

The aim was to investigate the literacy developmental trends across the years and establish which of the two variables, word identification skills or target language oral proficiency influenced reading comprehension performance. The results indicated that word identification skills independently influenced reading comprehension performance in both standard 2 and standard 3 classes, but target language oral skills did not. Further, the analysis of invented spelling task performance revealed evidence of transfer of alphabetic coding skills of first language to English orthography. The spelling errors reflected letter-sound patterns not found in English orthography. Analysis of the miscues in the spelling task revealed that children rely on first language phonological processes to spell target language unfamiliar words as long the languages have a common alphabetic system.展开更多

The impact of Music education for college students is also reflected as follow： to enable students to cultivate the art of perceptual knowledge, this ability is an art feeling, to help students better understand the artistic charm, to strengthen their own requirements and strive for a more noble art. It is necessary for college music major to have Performance capacity, Teaching ability, Management quality and Innovation capacity, referred to as ＂PTMI＂ complex talent. This article makes an analysis on that training goal of college music majors should be shifted toward ＂PTMI＂ complex talent.展开更多
