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.NBC宣布一次性续订《#我们这一天#》三季，即第四、五、六季，每季18集。
