This is because in the testing phase, ECOC coding has certain tolerance and correction ability for classifier errors. For example, the correct prediction code for the test example in fig. 3.5 (a) is (-1, +1, +1,-1, +1). Assuming that a classifier made an error during the prediction, for example, h made an error, resulting in the error code (-1,-1, +1,-1, +1), but the correct final classification result C3 can still be generated based on this code. Generally speaking, for the same learning task, the longer the ECOC code, the stronger the error correction ability.一个草台班子拍出来的电视剧，能有什么好看的？不怕不识货，就怕货比货。胡钧很快就让人在眉城做了几十副送来，这次正好派上用场。挂下电话，徐风一回身竟撞到了季木霖的身上，两个人都踉跄几步。From basic skills to methodology to character and mode of thinking, it is a process from "skill" to "Tao". However, unfortunately, many people blindly worship "Tao" and despise "Shu", but they do not know that the real Tao comes from the accumulation of Shu and the natural process from quantitative change to qualitative change. Without solid basic skills and systematic methodology, it is ignorant and opportunistic to talk about the so-called "philosophy, art and character" and rely on beautiful words and high-profile rhetoric to attract attention. Experience does not necessarily translate into theory, and scattered knowledge points do not necessarily rise to system integration. However, due to the lack of basic foundation and knowledge accumulation, the so-called "investment philosophy" can only be a joke. "Avenue to Jane" and "Avenue to Connect" are logically reasonable, because there are only a few great principles after high abstraction, but the difference between "technique" is very large because it is very meticulous. Therefore, what really troubles people is the process of combining and refining from art to Tao.　　八姑限房客每天只能用两桶水，做洗熨的上海婆(沈殿霞 饰)率先抗议，众房客支持，加上发仔(岳华 饰)、阿福(何守信 饰)附和，引出许多是非来……
