Abstract: A data fixed-point method, includes: calculating a maximum output value in a first target layer of a neural network for each input sample of a plurality of input samples; selecting at least two of a plurality of maximum output values as fixed-point reference values; determining a reference integer part bit width according to each of the fixed-point reference values; and performing an accuracy test based on a preset output value total bit width and each reference integer part bit width, to determine a reference integer part bit width with a highest accuracy as an integer part bit width used by the first target layer when output values are fixed-pointed.

Abstract: The present disclosure provides an image processing method. The method includes reading R rows of data of the image into a first storage buffer, R is an integer greater than 1; upsampling and filtering the R rows of data to obtain M rows of processed data, M is the upsampling multiple in the upsampling and filtering process, and M is an integer greater than 1. The method further includes reading a next row of data of the image into the first storage buffer after processing the R rows of data, the next row of data and the original R?1 rows of data in the first storage buffer are used as the R rows of data for the next upsampling and filtering process; and outputting the M rows of processed data.

Abstract: A noise source emits an acoustic noise wave with a noise frequency corresponding to an attribute of a control-status signal associated with the noise source. A method to reduce the noise comprises generating, based on the noise frequency corresponding to the attribute, an anti-noise signal having the noise frequency. The method further comprises phase-shifting the anti-noise signal to output a phase-shifted anti-noise signal that can be used to generate a noise-cancelling acoustic wave. The method can include aligning the first anti-noise signal to be in-phase with the acoustic noise wave. An anti-noise apparatus to implement the method includes an anti-noise generator, to generate the anti-noise signal, and a phase shifter to generate and output the phase-shifted anti-noise signal. The anti-noise apparatus can include a phase detector and phase alignment element to align the anti-noise signal to be in-phase with the acoustic noise wave.

Abstract: Frequently Asked Questions (FAQ) data are generated using Community-based Question Answering (CQA) data. A thematic hierarchy generation module receives multiple data sources and generates a thematic hierarchy of the data source, where a data source has one or more topics and a topic has one or more themes. A feature classifier classifies multiple CQA data into one or more themes based on the thematic hierarchy, where a CQA data contains multiple question-answer pairs. A selection module selects multiple question-answer pairs from the CQA data based on the classification, measures the quality of the selected question-answer pairs and generates FAQ data using the selected question-answer pairs of the CQA data.

Abstract: A blind-rivet gun includes a gun header, a cylinder, a piston, and a tube. The cylinder is separated from the gun header. The piston includes a piston header. The piston header and an inner surface of the cylinder form a seal to divide the cylinder into a first air chamber and a second air chamber. The cylinder includes a first gas hole and a second gas hole. The first gas hole is connected to the first air chamber, and the second gas hole is connected to the second air chamber. The piston is adapted to slide in the cylinder to generate inner high pressure gas by alternatively supplying outer high pressure gas to the first gas hole or the second gas hole. The tube is connected to the gun header and the cylinder. The tube transmits inner high pressure from the cylinder to the gun header.
