Check the performance of the regression algorithms



how to check the performance of the algorithm and compare it with others??? is there article for this in python??in hackathons when we do not have the true result of the test set how to check the performance???and for classification problems also.


@9954953559 you can use k-fold cross-validation to compare different models. This post will help you - How K-fold Cross-validation helps in improving the model?


the most common way to comparing two algorithms by these following ways
1.time complexity complexity
3.Ease of implementation/ adaptation of algorithm
