Effects of category distribution in a training set on text categorization;

A simplification SVM model based on guard vectors is proposed for overcoming the slow speed of training and classification for large scale training set.

For this method,in the training process,a simple classifier based on the idea of each class having a center is designed,which can select efficient data from plenty of unlabeled data to label and then add into the SVM training set.

The key for implementing professional skills identification lies in taking modularized curriculum system as the framework,integrating skills identification with diploma education examination,adopting the method of combination of curriculum alternation,concentration training with examination for certificate,and strengthening the cultivation of students operational abilities.

Error correlation,which acts as a parameter to select the training subset from training set,is developed to improve the generalizability of learning machine.

The study of the influence of group training on moral traits of undergraduates shows that the cohesiveness index is significantly improved after training.

Those in test group received group training with self-designed community based motor function rehabilitation simple technique combi.
