Publication number: 20240185066Abstract: In a method for performing one bit quantization of data, data for training a neural network is received. The data is applied to a classifier of the neural network to determine classification probabilities for the data. A loss function is applied to the classification probabilities for the data, the loss function including a regularizer, where the regularizer forces weights of the classification probabilities to converge to binary integers, and where the regularizer exhibits a smooth curve with a continuously turning tangent at a midpoint. The quantized weights of the classification probabilities for the data is output.Type: ApplicationFiled: November 20, 2023Publication date: June 6, 2024Applicant: TDK CORPORATIONInventors: Etienne De FORAS, Minh Tri LE

Patent number: 10852157Abstract: A method and apparatus of controlling movement of an aircraft. A turn path off of a planned route for an aircraft comprising a turn to direct the aircraft to an intercept point on the planned route is determined. A planned route indicator depicting the planned route, a turn path indicator depicting the turn path, and an aircraft position indicator indicating a position of the aircraft are displayed to an operator of the aircraft at the same time on a turn guidance display. Deviation limit indicators for the planned route, the turn path, or both, may be displayed on the turn guidance display.
