UnverifiedThe study's clearest conclusion is that fine-tuning on a small amount of high-quality annotated data significantly outperforms larger but noisier mixed datasets, with statistical significance at p < 0.01.74% similarUnverifiedMacro-average accuracy first computes the accuracy of each class separately and then takes the arithmetic mean, making it more sensitive to the performance of minority classes; overall accuracy is the proportion of all samples predicted correctly and is easily affected by the class sample size distribution.73% similarUnverifiedAccording to the study's description, this processing noticeably improves the model's accuracy and consistency of judgment on samples involving binary payloads—the blind spot is partially filled.72% similarUnverifiedIn imbalanced classification problems, a model can achieve very high accuracy even by predicting all samples as the majority class, so it is necessary to shift to more discriminative metrics such as precision-recall curves, F1 score, Matthews correlation coefficient, or AUC-ROC72% similarUnverifiedAssuming the data follows a Gaussian distribution, maximizing the likelihood is equivalent to minimizing the mean squared error.71% similar
