Abstract: Disclosed in the present invention is a differentiable method for mining constant rules. On the basis of defining constant operators and path operators according to a knowledge graph, a fusion attention mechanism is used to evaluate relations passed by rules by using attention values. Meanwhile, attentions are calculated by aggregating surrounding attributes and the corresponding attribute values for tail node of each hop respectively. Attentions of the attributes are used to enhance selection of relations in the rules to achieve link prediction. According to generated model parameters, high quality symbolic rules are output by parameter analysis and statistics. This method is particularly suitable for application scenarios with complex reasoning requirements that require high prediction accuracy, provide interpretations for predictions, and need to precipitate reasoning rules.

Abstract: A pipeline ADC architecture with suitable feedback can implement noise shaping. By feeding back the residue generated by the last residue generating stage to selected locations in the pipeline ADC, the delays in a pipeline ADC can create a finite impulse response (FIR) filtered version of the quantization error. The FIR filtered quantization error is added to the signal and evaluated by the pipeline ADC, which results in spectral shaping of the quantization noise. Unlike a conventional pipeline ADC, the output of the backend stage is scaled and filtered by a noise transfer function (NTF) of the residue generating stages prior to combining the output with other outputs of the pipeline ADC. The processing of the shaped quantization noise by the backend stage results in further noise suppression.
