Error-aware Quantization through Noise Tempering

, 2022
Quantization has become a predominant approach for model compression, enabling deployment of large models trained on GPUs onto smaller form-factor devices for inference. Quantization-aware training (QAT) optimizes model parameters with respect to the end task while simulating quantization error, leading to better performance than post-training ...

Stochastic Quantization of Real-Time Thermal Field Theory

, 2009
We use the stochastic quantization method to obtain the free scalar propagator of a finite temperature field theory formulated in Minkowski spacetime. First we use the Markovian stochastic quantization approach to present the two-point function of the ...

High--$T_c$ RF SQUIDs with Large Inductance of Quantization Loop

, 2003
Experimental data on signal and noise characteristics of high--$T_c$ RF SQUIDs with large inductance of quantization loop are presented. The SQUIDs were produced by a thick--film HTS--technique of painting on the Y$_2$BaCuO$_5$ substrate.
