This caching policy makes good use of the characteristic of the Dynamic Batched Patching algorithm; the results of simulation have proved thatthis caching policy can obtain a high Byte Hit Ratio, that is, this caching policy can decrease the requirement of video server I/O bandwidth even in the context of efficient multicast system.

該策略充分利用了第三章中提出的多播傳輸機(jī)制的優(yōu)點(diǎn)2019在线中文字幕网站视频，即使在這種高效傳輸機(jī)制下最真实的偷拍网，還可以獲得較高的Byte Hit Ratio，也就是說(shuō)本策略對(duì)減少服務(wù)器I/O帶寬的消耗有著明顯的效果VIP专区色哟哟。

The prediction by using repeated learning of system with four variables makes a remarkable result. In this case, the predictability can reach to 77.4% on average. Even expert makes prediction from more information, the hit ratio and direction hit of prediction by model is higher 15% than that by expert.

With process data of blast furnace No.1 in Tianjin Iron Plant, the parameters, Ru and Sita, of model have been optimized based on criteria of predictability, hit ratio, direction hit ratio and mean sum of square error according to each variable respectively.
