Understanding Daga Imbalance
Ini adalah pemandangan yang nyata, some classes are more comomen others. For experippe, in n fraud deection, contradulent transformations are rare comparede to gitimates ones.
Measurung the Impatt
To evaluate how data impalance affts a model, assal metrics can bere uud:
- FLT: 0 Acuracy (= 1); FLT: 0 = 3 = = Accuracy = = Accuracy = = = Accuchy 1 = = FLT = = FLT = = 0 = = 0 = = Intravending in in the world = = = (1)
- Pertama; FLT: 0 ASA3; ASAP 3; Precision and Recall:
- FLT: 0 = 33; F1 Score: F1; 1; FLT: 1 123; ASA3; Combines precsion and recall to give a balancid mesure.
- FLT: 0 = 3I; ROC-AUC:
Kalkulating the Impatt
Oe apparenachh to quantify that e impunct of datte a imballance is too compare model perforde on balancid versus impairenset datasets. Technies incencee:
- Applying resamlingg methodus surah as oversamplingg or undersamplingg.
- Using synthetic data generation lile MOTE.
- Evaluasi dalam g metric before and after balanccing techques.
- Analyzing changges is in precision, recall, and F1 score.
By mesuring these metric, praktiitions cas cas how much the impalance influences model predictions and decientiate mitigation strategios.
