First, we recommend you read the article: from N to N+1:multiclass Transfer Incremental Learning Core thought is transfer Incremental learning In the traditional machine learning hypothesis the training data and the predictive data obey the same data distribution. In many cases, however, the assumption of this distribution is not satisfied. Situations that do not satisfy the same distribution assumptions often occur when training data expires, and it

Learning XML Today encountered this problem, Internet access to data analysis, the main reason for this problem is that the XML file is declared in the XML file itself when the encoding is inconsistent.
