Annotated version of focal loss of retinanet
It mainly writes about how to specifically calculate positive and negative samples for focal loss and how to use iou loss. class FocalLoss(nn.Module): #def __init__(self): def forward(self, classifications, regressions, anchors, annotations): alpha = 0.25 gamma = 2.0 batch_size = classifications.shape[0] classification_losses = [] regression_losses = [] # The anchors for different batches are the same […]
RetinaFace face detection model-Gradio interface design
Foreword This article is based on the intelligent target detection 42 of Bubbliiiiing, a leader in the field of artificial intelligence – Pytorch builds a Retinaface face detection and key point positioning platform Original link: https://blog.csdn.net/weixin_44791964/article/details/106872072 These are my study notes, which record my learning process of local reproduction, repackaging and function expansion of open […]

RetinaNet code analysis
Code Analysis head The branches output by Fpn, each of which will perform classification and regression operations classification output Each layer of features undergoes 4 convolutions + relu operations, and then through the head convolution self.output = nn.Conv2d(feature_size, num_anchors * num_classes, kernel_size=3, padding=1) self. output_act = nn. Sigmoid() Output the final predicted output, scale is […]
