自适应池化Adaptive Pooling与标准的Max/AvgPooling区别在于,自适应池化Adaptive Pooling会根据输入的参数来控制输出output_size,而标准的Max/AvgPooling是通过kernel_size,stride与padding来计算output_size: output_size = ceil ( (input_size+2∗padding−kernel_size)/stride)+1 Adaptive Pooling仅存在与PyTorch,如...

nn.AdaptiveAvgPool2d与AdaptiveMaxPool2d 关于PyTorch含有的自适应池化Adaptive Pooling池化层 学习目标:自适应池化层 疑惑:在设计神经网络模型的时候,往往需要将特征图与分类对应上,即需要卷积层到全连接层的过渡。但在这个过渡期,不知道首个全连接层的初始化输入设置为多少? 学习内容:代码示例 ...
Faster-RCNN论文中在RoI-Head网络中,将128个RoI区域对应的feature map进行截取,而后利用RoI pooling层输出7*7大小的feature map。在pytorch中可以利用: torch.nn.functional.adaptive_max_pool2d(input, output_size, return_indices=False) torch.nn.AdaptiveMaxPool2d(output_size, return_indices=False) 这个函数...
多数的前向推理框架不支持AdaptivePooing操作,此时需要将AdaptivePooing操作转换为普通的Pooling操作。AdaptivePooling与Max/AvgPooling相互转换提供了一种转换方法,但我在Pytorch1.6中的测试结果是错误的。通过查看Pytorch源码(pytorch-master\aten\src\ATen\native\AdaptiveAveragePooling.cpp)我找出了正确的转换方式。

Adaptive pooling is a great function, but how does it work? It seems to be inserting pads or shrinking/expanding kernel sizes in what seems like a pattered but fairly arbitrary way. The pytorch documentation I can find is not more descriptive than "put desired output size here." Does anyon...
