"Systems and methods for applying semi-discrete calculus to meta machine learning" was invented by Amir Shachar (Haifa, Israel).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method and system for building and implementing a meta-machine learning (meta-ML) optimization engine for a neural network (NN) or a machine learning (ML) connective model. A computer processor may iteratively simulate a backpropagation algorithm by executing a sequence of optimization steps. At each optimization step a position of a loss function may be determined that may be closer than a previously determ...
