An object of the invention is to provide a polishing pad that achieves a high polishing rate and has high thickness precision so that the break-in time can be shortened, and to provide a method for producing same. Typically, the target proteins have a function which has not yet been elucidated. The arteriographic image sequences maybe obtained from a biplane imaging system or from two sequences of images using a single plane imaging system. Next, a second neural network is updated at a first rate, with an output of a first neural network, wherein the output is based on the inputted signals.
