Asian Agricultural Research 2012年第8期4卷 90-92页

作者： ZHANG Shuang-na Department of Economics,Shandong Youth University of Political Science,Jinan 250014,china

The core of issues concerning agriculture,countryside and farmers is farmer problem,and the key to farmer problem is the problem of farmers' overall quality. Farmers' cultural quality,technical level and ideological and moral standards,directly determine the success of countryside construction and agricultural development. Therefore,many countries have attached great importance to farmers' education and training,and established the training mode with their own characteristics,playing an important role in improving the comprehensive quality of farmers,promoting the advance of social modernization,and propelling sustainable social development. By probing into the history of the development of foreign farmers' education and training,I summarize the main features,and conduct in-depth scientific analysis,which will provide a reference for developing farmers' education and training,and resolving issues concerning agriculture,countryside and farmers in china during the period of social transformation.

This paper proposes an intrusion detection method combining rough set with ADA-boost algorithm. In virtue of the ability rough set has to decease the amount of data and get rid of redundancy, the method can reduce the a-mount of ADAboost’training data used and imp-rove running speed. Adaboost is a learning al-gorithm for constructing accurate classifiers. It can obtain a strong learning algorithm by combining a series of weak learning algorithms through some *** result of the experiment shows that this model has high detection rate .
