Research for Intelligent Teaching Aid Base on ARM7

In order to solve such existing problems as low intelligent level of teaching aid and huge systematic size, this paper studies a kind of intelligent system of teaching aid based on knowledge discovery, and discusses the method that can realize knowledge discovery on small-sized embedded system. To break through traditional technology of data fitting, it puts forward the method of orthogonal polynomial. Also in order to avoid combination explosion while searching blindly, it uses heuristic search function in artificial intelligence to reduce searching frequency, and enhance the automation level of knowledge discovery.
