Latest Patents

One of his latest patents focuses on energy-efficient scheduling of industrial processes by reducing idle time and tardiness of jobs. This computer-implemented method involves receiving jobs to be executed on machines within a manufacturing facility. A job schedule is generated based on an optimization function that minimizes total energy costs for all machines during a specified time horizon. The energy cost at each time step is calculated based on various modes of machine operation, including sleeping, stand-by, and processing modes. The jobs are executed on the machines according to the generated job schedule.

Another significant patent addresses efficient calculations of negative curvature in a Hessian-free deep learning framework. This method for training a deep learning network includes defining a loss function and receiving training samples. An optimization method is then applied to iteratively minimize the loss function. Each iteration involves using an eigCG solver to determine a descent direction, which helps prevent the optimization method from converging to saddle points. Curvilinear and adaptive line-searches guide the optimization method to a local minimum, ensuring effective training of the deep learning network.
