The data set is generally divided into three parts: train set, valid set, test set It is used to train the model, adjust the hyper-parameters and test the model. Where valid set is a

Phase:now You apply your freshly-developed model to the Real-world data and get the results. Since you normally don ' t has any reference value in this type of data (otherwise, why would do need your model?), you CA N only speculate about the quality of your model output using the results of your validation phase. The validation phase is often split into a parts:in the first part of you just look at your models and select the best per Forming approach using the validation data (=validation) th

should be so understanding in the training set effect is good, in the test set effect is poor, should be model's generalization ability is too bad. Train on all data sets to get the best ACC 88% but on the test set there are 76% How to do this: 1. Uneven sample The total sa

Performance Long time no come, this time to bring you a little dongdong. We all know that Julia set is an iterative algorithm, that is, the results of the operation are put into the algorithm calculation, so that the results are close to the real value For example, we calculate π,e using this algorithm. Julia sets have many forms that require a lot of resources to produce results. And we can use this algorithm to
