convolution - Is there a correct order of "conv2d", "batchnorm2d ...
May 29, 2023 · After investigating the structure of the official UNet architecture as proposed in the official paper I noticed a recurrent pattern of Conv2d->BatchNorm2d->ReLU (->MaxPool2d) …
Confusion about conversion of RGB image to grayscale image using a ...
Aug 2, 2021 · Note the groups parameter of Conv2d, which affects how the channels are convolved. The default is 1, which means: At groups=1, all inputs are convolved to all outputs. If you set it to 3 (and 3 …
reinforcement learning - 2D convolution with channels versus 3D ...
Apr 4, 2023 · In PyTorch's Conv2d function, if I set groups=1 then all input channels are convolved with all output channels as in the formula. Does this capture interaction between channels? Approach 2 …
How is the convolution layer is usually implemented in practice?
Joking apart, in PyTorch Conv2d is a layer that applies another low level function, conv2d, written in c++. Luckily enough, the guys from PyTorch wrote the general idea of how convolution is …
Why is the convolution layer called Conv2D?
Aug 21, 2020 · A 2D convolution is a convolution where the kernel has the same depth as the input, so, in theory, you do not need to specify the depth of the kernel, if you know the depth of the input. I …
computer vision - Is there a best practice for creating multiple ...
Oct 4, 2022 · With all the work being done on larger and larger images, I'd like to ask if a best practice(s) has arisen for allowing multiple convolutional layers on small image inputs? For instance, in my case I

Aug 10, 2024 · What is the channel dimension other than color representation in Conv2D? Shall I use Conv3D instead? Ask Question Asked 1 year, 3 months ago Modified 1 year, 3 months ago
neural networks - How to use a conv2d layer after a flatten ...
Dec 10, 2020 · So, I was wondering if I used a pretrained model (EfficientNet for example) if I want to change the _fc attribute and use conv2d in it, how can I recover a 2D structure? Because the …
neural networks - Convolution layer, with biases too? - Artificial ...
Aug 16, 2023 · For example the TensforFlow Keras Conv2D layer has bias optional, but enabled by default. Making the bias a learnable "kernel" that adds separately would not do anything different …
