WebAug 28, 2024 · RetinaNet object detection method uses an α-balanced variant of the focal loss, where α=0.25, γ=2 works the best. So focal loss can be defined as –. FL (p t) = -α t (1- p t) γ log log (p t ). The focal loss is visualized for several values of γ∈ [0,5], refer Figure 1. WebSurvey on Loss for Heatmap Regression. I am trying to work out which loss function is better for Heatmap regression, for face keypoint detection project. I am looking for losses that are compatible with other domains like Human pose estimation which also use heatmaps. I currently am using MSE as loss, and want to implement either Adaptive …
