Hyperparameter optimization (HPO) is a necessary step to ensure the best possible performance of Machine Learning (ML) algorithms. Several methods have been developed to perform HPO; most of these are focused on optimizing one performance measure (usually an error-based measure), and the literature...

Nevertheless, it is possible to use alternate optimization algorithms to fit a regression model to a training dataset. This can be a useful exercise to learn more about how regression functions and the central nature of optimization in applied machine learning. It may also be required for regressi...
Optimization Algorithms 对于深度学习问题,我们通常定义loss function,使用优化算法来最小化该loss function。在优化的过程中,loss function被当做优化问题的objective function。本质上,优化和深度学习的目标不一致,前者的目标是最小化目标函数,而后者是在有限数据的情况下找到合适的model,即优化的目标是减少training error...
