Look at our more comprehensive introductory tutorial which introduces the optim package, data loaders etc. Some of the most intriguing applications of Artificial Intelligence have been in Natural Language Processing. The objective is to sub-sample an input representation (image for example), by reducing its size and by making assumptions on the characteristics contained in the grouped sub-regions. The MPC optimization problem can be efficiently solved with a number of methods, for example the finite-horizon iterative Linear Quadratic Regulator (iLQR) algorithm.
