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
