东环市公安局重案队正在庆祝“清网行动”取得重大胜利：将一名负案在逃多年的嫌疑人捕获归案。突然得知发生了惊人血案，一名公安民警被歹徒偷袭致重伤，身上的枪和子弹被抢走。公安局立刻派出重案队全力侦破，上级机关也派刑侦副处长高林前来督导破案。高林会同重案队长洪顺达及从重案队调走的派出所干警许毅共同组成专案组。这三人是警校同学，生活中又有着千丝万缕的联系。他们克服了生活中相互之间的种种误会，与案犯斗智斗勇，经过大量的侦查，许毅发现案犯孙志军的父亲曾被自己的父亲抓捕入狱，确定这次是其报复作案。三人及专案组立刻全力对孙进行追捕，通过斗智斗勇的多次较量，终将其围困在山野间，经激烈枪战，临近退休的干警老丁则在紧急关头为保护许毅中弹牺牲。最后许毅亲手将孙志军击毙，成功破获此案。

Information Theory: I forget which publishing house it was. It is a very thin book and it is very good. There is a good talk about the measurement of information, the understanding of entropy and the Markov process (there is no such thing in the company now, I'll go back and find it and make it up). Mastering this knowledge, it is good for you to understand the cross entropy and relative entropy, which look similar but easy to confuse. At least you know why many machine learning algorithms like to use cross entropy as cost function ~
