A method and a system for exercising policy control, a policy and charging enforcement function (PCEF) are provided, which can solve the problem that no policy control can be exercised over application service flows without an application function (AF). In the method, a PCRF receives information about an application event sent by a PCEF after subscribing the application event from the PCEF; and the PCRF generates a control policy for a service flow of the application according to the information about the application event. In the present invention, the PCEF sends the obtained information about the application event to the PCRF, so that even when no AF is involved, the PCRF can still generate a control policy according to policy contexts including the information about the application event and the like.

Approaches for determining quantization scale factors include generating a population of chromosomes. Each chromosome has multiple genes, and each gene specifies a scale factor associated with a layer of a machine learning model. The population of chromosomes are evaluated, and the evaluating includes, for each chromosome in the population, quantizing floating point weights and floating point values of a representative dataset using the scale factors of the chromosome to produce quantized weights and a quantized dataset in the memory arrangement, initiating processing of the quantized dataset using the quantized weights according to the machine learning model, and gauging a level of accuracy of results produced by the processing of the quantized dataset. Satisfaction of termination criteria is determined based the levels of accuracy associated with the chromosomes in the population. The population of chromosomes is evolved and the evaluating repeated in response to the termination criteria not being satisfied.
