This paper proceeding from the methodology of systematology, information theory and cybernatics, emphasizes the effect of meaning measuring system and three experimental principles of random, repeated, part control"to the dec-rease of data undeterminedness and to the increase of the information content and the value shared by society. Introduces the recently developed multivaria-te-quadratic-(also cubic-) turning-regressive-method based on the theory of combinative designed experiment. Taking the terrain-tyre problem as an examp-le,this paper illustrates that this method can be used for unified consideration. of experimental design and for data processing, for the establishment of mat-hnatical models, for statistical inspecting and for simulated analyzing with electronic computer. The controlling and predicting accuracy of parameters and performance data also can be calculated.The author has made preliminary study on the means of application and prospects of the above mentioned method for the comprehensive revealing of in-ternal relations and complex pattern of numerous parameters in terrain-machine system.

Human face is a very common complex pattern, it is difficult but quite important to detect faces in a complex background. In fact, face detection is also a prerequisite for face recognition. An approach to this issue is presented, which is based on multi layer perceptron and genetic algorithm. The experimental results show that this system is good especially at low resolution and complex ima ges and is robust, quick and widely applicable. However, its applications are limited as it is required that faces in an image must be of approximate sizes. The paper introduces this system and gives a theoretical analysis about the mechanism of this approach, that is, multi layer perceptron for sensing faces directly on gray data and genetic algorithm for searching faces in the scene.
