我在YOLOv5中采用Pconv(输入通道是c)+conv1x1(输入通道c,输出通道2c)组合的方式替换conv3x3(输入通道是c、输出通道是2c),特征图尺度是没有改变的,测试后精度和速度均降低了;我想请问是需要采用Fasternet Block进行来替换conv3x3嘛?它的输入通道、输出通道该怎么设置呢?是否能够提升检测速度?

你的效果怎么样?从实验结果来看,在表1中,作者比较了相同输入相同输出时使用不同卷积核的推理速度,但是没有比较这时候的精度;在表3中,作者比较了相近参数相近浮点运算数时的推理速度和准确率,由于作者使用的是PConv和1x1卷积,所以相同参数下输出的通道数应该是比较大的。因此,或许,当输入输出通道数一样时效果可能不好,需要扩大输入输出通道数。

要多多实验,这个东西不是口头能说出来的,部分卷积只能说作为一个降低复杂度的思路,具体还得实验

您有做了尝试吗,效果提升了吗。我这里有点报错问题
