In conventional optical components, such as lenses or gratings, the propagation of light is usually manipulated by reflection, refraction or diffraction. For example, a wavefront can be modified using ...
The strength–ductility trade-off has been a long-standing dilemma in materials science. This has limited the potential of many structural materials, steels in particular. Here we report a way of ...
Dr. James McCaffrey of Microsoft Research explains stochastic gradient descent (SGD) neural network training, specifically implementing a bio-inspired optimization technique called differential ...
