Despite many textbooks listing stepwise search as a valid option, it almost always underperforms other supervised methods such as regularization.
实际观察结果表明,现代深度网络都没有得到充分正则化:.
In practice, a number of observations suggest that modern deep networks are under-regularized.
在下一篇文章(课程2)中,我们将看到如何通过超参数调整、正则化和优化来改进深度神经网络。
In the next article(which will cover course 2), we will see how we can improve deep neural networks by hyperparameter tuning, regularization and optimization.
Some of these methods, in particular linear SVMs, regularized logistic regression and regularized linear regression, are among the most effective known methods….
All options have in common that you need to add configuration of some hyper-parameters, i.e.“high-level” parameters like problem type, feature selection, or regularization level.
KDnuggets Editors bring you the answers to 20 Questions to Detect Fake Data Scientists, including what is regularization, Data Scientists we admire, model validation, and more.
In particular, neural layers, cost functions, optimizers, initialization schemes, activation functions, regularization schemes are all standalone modules that you can combine to create new models.
