QR-Decomposition

QR decomposition can be useful in machine learning applications. An example of using QR decomposition in machine learning is the automatic removal of an object from an image. Imagine wanting to crop the image of a car from a video clip. Using what is known as single value decomposition, it becomes relatively simple. In short, by splitting the video into its individual frames, turning the frames into 1D vectors, and creating a matrices of the vectors corresponding to each image, one can then run a single value decomposition on the video.
