我隐约中听到她手机中传来主播的一句话：“朋友们，听懂我的意思了吗？懂得扣个1，不懂得扣个0 ”。
重新思考任务运行机制 训练过程中,我发现loss_cls完好,可以正常进行反向传播,但是box loss会直接崩溃掉,仔细观察数据集本身和任务模型代码,由于我的训练样本集中存在大量的密集分布的小样本,在网络降采样过程中极易vanish,比如我在某处检测网格中存在目标,但由于网络检测不到,会导致mask为0,但anchors匹配样本得到的却是...
NLP: NLP 2 in 1 BOX SET: NLP for Fast Weight Loss+ Success Secrets: Change Your Life with Neuro-Linguistic ProgrammingJames Adler
bbox_weights:tensor(B*H*W*num_anchors, ),取值0、1 ,正样本为1 ,负样本和忽略样本为0,这样计算分类loss不会计算忽略样本和负样本。 avg_factor:计算平均loss时的分母。若采用了bbox sampler,那么为正+负样本数,若没有采用bbox sampler,那么仅为正样本数。 1. L1Loss 就是最简单的绝对值loss,公式:los...

你好, 基于独立数据集训练时,bbox_loss始终是0,模型无法预估。 训练如下, inferece时报错, 我的train config文件是: test_haomi_v06101440.txt 我的train.json文件是: train_direct.json 我的label.json文件是: label.json 求助, 辛苦帮忙看下为什么bbox loss始终
