请问NMS及其改进? #11853
Comments
@jkocherhans 感谢,盼复! |
@18846169373 hi there, Thank you for bringing up your questions and sharing your code improvement attempts for soft-NMS in YOLOv5. I'll be happy to assist you. To answer your questions:
I hope this helps! If you have any further questions or need additional assistance, please feel free to ask. Best regards. |
感谢您如此迅速的回复! |
@18846169373 感谢您的追问! 关于您的问题: 1、在YOLOv5的训练阶段,预测框的筛选和计算损失是通过IoU(交并比)阈值来实现的。在训练过程中,如果一个预测框与标注框之间的IoU大于设定的阈值,则该预测框被视为正样本,用于计算损失。这种方式可以在训练过程中有效地筛选出与目标物体重叠较好的预测框。 2、关于您在训练阶段使用改进的NMS技术后出现结果差异的问题,这可能是由于几个原因引起的。首先,改进的NMS技术可能与模型的训练目标和损失函数不兼容,导致训练过程中的优化效果降低。其次,改进的NMS技术可能与训练数据集的特点不匹配,导致模型在测试阶段无法准确预测。最后,可能存在代码错误或参数设置问题。建议您仔细检查代码实现和参数设置,确保正确性。 希望以上回答能解决您的疑问。如果您还有其他问题或需要进一步帮助,请随时提问。 祝您工作顺利! |
Thank you!祝好! |

Question
您好!jkocherhans 。最近我尝试在YOLOv5中改进soft-NMS及其变形,但是效果很不好,希望得到你的帮助
1、请问NMS在v5训练阶段有使用么?
2、改进后的模型,训练很慢且效果不好,是我的代码有bug么?
3、我可以将模型正常训练但是使用改进后的增强NMS进行测试么?您认为这会是有效的改进么?
