Abstract: A method of generating a fixed-point type neural network by quantizing a floating-point type neural network, includes obtaining, by a device, a plurality of post-activation values by applying an activation function to a plurality of activation values that are received from a layer included in the floating-point type neural network, and deriving, by the device, a plurality of statistical characteristics for at least some of the plurality of post-activation values. The method further includes determining, by the device, a step size for the quantizing of the floating-point type neural network, based on the plurality of statistical characteristics, and determining, by the device, a final fraction length for the fixed-point type neural network, based on the step size.

Abstract: Methods and apparatuses for managing wireless signal information for positioning a mobile terminal are provided. The wireless signal information obtained by measuring a signal characteristic with respect to access points of a target area, is stored in a database. At least one piece of position error information calculated based on the wireless signal information is received from at least one mobile terminal. A positioning reliability is assessed with respect to the target area, based on the at least one piece of position error information. It is determined whether to update the wireless signal information, based on the assessed position reliability.
