1. Training error: The error of the learner in the training set, also known as "experience Error"2. Generalization error: The error of the learner on the new sampleObviously, our goal is to get a better learner on a new sample, which is a small generalization error.3. Overfitting: The learner learns the training sample too well, leading to a decline in generalization performance (learning too much ...). Let me think of some people bookworm, reading de

Li Hang, chief scientist at Huawei Noah's Ark lab
Li Hang said: so far, we have found that the most effective means of AI research in other fields may be based on data. Using machine learning, we can make our machines more intelligent.
At the same time, Li Hang believes that we need a lot of data to learn exactly how much data we
and data mining:the overall goal of the data mining process are to extract Information from a data set and transform it to an understandable structure for further use.Machine learning also have intimate ties to optimization:?

straight line, but it does not need to be guaranteed.That is, to tolerate those error points, but we have to add the penalty function so that the more reasonable the error points, the better. In fact, in many cases, the more perfect the classification function is not during training, the better, because some data in the training function is inherently noisy. It may be wrong when the classification label is manually added, if we have learned these error points during training (
