WebSep 4, 2015 · This is how coherent sources were first defined in optics. In contrast, incoherent optical sources, even if monochromatic, produce an ensemble, or statistical superposition, of light waves with random relative phases (and polarizations, to be precise), which do not/cannot interfere which each other. Web2 days ago · The team then trained a neural network to examine an image and generate a bipolar hypervector — an element can be +1 or −1 — that’s as close as possible to some superposition of hypervectors in the dictionary; the generated hypervector thus contains information about all the objects and their attributes in the image.
