Optimization and Machine Learning Optimization for Machine Learning Suvrit Sra Sebastian Nowozin Stephen J. Uncertainty can be explicitly introduced when the data collection process is noisy or some data are cor-rupted. First-order optimization algorithms are very commonly employed in machine learning problems such as classification and object recognition and many methods have been developed to accelerate these large optimization problems.
For a convex optimization problem the objective function and the inequality constraint lets call the function f x need to be convex functions and the equality constraint lets call the function g x should be an affine function. As a practitioner we optimize for the most suitable hyperparameters or the subset of features. In machine learning the idea is you have some data set and youre trying to train the.
