WebFeb 1, 2024 · By design, average precision (AP) for object detection aims to treat all classes independently: AP is computed independently per category and averaged. On one hand, this is desirable as it treats all classes equally. On the other hand, it ignores cross-category confidence calibration, a key property in real-world use cases. l200 2017 tabela fipeWebJan 25, 2024 · Hamming Loss = 1 n L ∑ i = 1 n ∑ j = 1 L I ( y i j ≠ y ^ i j) where I is the indicator function.
