摘要：
A data compression method using a template, in which a template optimizing means using an artificial intelligent technique (such as a genetic algorithm) applied to segments defined by diving input data into uniform segment units contributes to enhancing the prediction accuracy, data is compressed using the results of optimization, and a database is updated to improve the compression efficiency and speed of the subsequent processings. By updating a database by using an optimized template, a template for improving the prediction accuracy is obtained quickly without applying any artificial intelligent technique.
