WebApr 9, 2024 · Given that both the f1-score and PR AUC are very low even for the prevalence of ~0.45%, it can not be deduced if the limitations are imposed by the nature of the data or the model (features plus the algorithm used).. In order to build a better understanding and to resolve the issue, I would suggest to break the problem into two parts: Build a model that … WebMay 23, 2024 · High recall: A high recall means that most of the positive cases (TP+FN) will be labeled as positive (TP). This will likely lead to a higher number of FP measurements, and a lower overall accuracy. ... An f-score is a way to measure a model’s accuracy based on recall and precision. There’s a general case F-score, called the F1-score (which ...
