- class hybrid_learning.concepts.train_eval.kpis.batch_kpis.BalancedPenaltyReducedFocalLoss(factor_pos_class=0.5, alpha=2, beta=4)[source]
Bases:
ModuleBalanced version of the penalty reduced focal loss from CenterNet. Formula (with focal loss parameters \(\alpha,\beta\) and balancing factor \(b\in[0,1]\)):
\[L(M, M^{pred}) = - \frac{1}{#(M\eqiv 1} \cdot \left( b\cdot \sum_{xy, M_{xy} \equiv 1} (1-M_{xy}^{pred})^\alpha \log(M_{xy}^{pred}) + (1-b)\cdot \sum_{xy, M_{xy} < 1} (1-M_{xy})^\beta (M_{xy}^{pred})^\alpha \log(M_{xy}^{pred}) \right)\]Public Data Attributes:
