此外，在利用人工神经网络对类似的大样本系统进行辨识时，如果能采用一些数学上的处理技巧。

Furthermore, it will greatly enhance the speed of training if some proper mathematic techniques are adopted in the application of artificial neural network to identifying similar big sample system.

本系统解决的第一个问题是：IRT理论模型有较严苛的基本假设，因此需要建设大样本配合的题库。

The first problem that the system faces: as IRT theory model is imposed severer basic assumptions, so large groups of samples are needed to build the Item bank.

由于采用随机存取技术和一些新算法，使本系统可在微机土对大样本问题进行聚类分析，从而提高了系统的实用性。

With the use of random access technology and some new algorithms, the clustering analysis of large sample can be processed on microcomputer. Thus practicality of this program system is improved.
