MAPE is a commonly used accuracy metric in regression tasks, calculated as the absolute value of the difference between the predicted value and the true value divided by the true value, then averaged over all samples and multiplied by 100%; its limitation is that when the true value is close to zero it gets amplified or even undefined, so it is more applicable in industrial scenarios such as flow rate and production volume where values are always positive and of stable magnitude.

UnverifiedThe actual benefits of low-precision solutions are highly dependent on specific model shapes, and real-world deployment requires empirical validation against one's own workload rather than directly applying peak numbers.64% similarUnverifiedWhen the ledger counts pass rates by row, each row has equal weight rather than equal weight by goal or task; if a goal contributes a large number of records due to high run frequency and many loop iterations, it will occupy a weight in the overall average far beyond its true value (dilution effect), and the mitigation is to report stratified by goal or to compute per goal first and then aggregate.64% similarUnverifiedMPE is defined as the expected optimal conditional prediction accuracy minus the optimal static prediction accuracy.63% similarUnverifiedA confidence threshold is a lightweight uncertainty measure, implemented by checking whether the output length is far below the expected value, detecting vague wording, or comparing the consistency of multiple sampled results.61% similar
