Focal Loss can be interpreted as a binary cross-entropy function multiplied by a modulating factor (1- pₜ)^γ which reduces the contribution of easy-to-classify samples. The weighting factor aₜ balances the modulating factor.Quoting from the authors: “with γ = 2, an example classified with pt = 0.9 would have

    Nov 19, 2017 The model produces three probabilities as you show and just from the first output you provided [ 7.93856847e-06 9.99989550e-01 2.51164967e-06] class 2 has a higher probability, so I can't see the problem here. Class 0 is the first class, class 1 is actually class 2 the second class, 2 is the third class. So I guess nothing is wrong
