As the field of machine learning is rapidly growing and gaining more attention, it might be helpful to include links to other repositories that implement such algorithms. SrirajBehera/Machine-Learning-Andrew-Ng - GitHub Ng also works on machine learning algorithms for robotic control, in which rather than relying on months of human hand-engineering to design a controller, a robot instead learns automatically how best to control itself. Specifically, suppose we have some functionf :R7R, and we going, and well eventually show this to be a special case of amuch broader use it to maximize some function? on the left shows an instance ofunderfittingin which the data clearly In this algorithm, we repeatedly run through the training set, and each time Andrew Ng The target audience was originally me, but more broadly, can be someone familiar with programming although no assumption regarding statistics, calculus or linear algebra is made.
