09.07.2020 · In this article, we will define a Convolutional Autoencoder in PyTorch and train it on the CIFAR-10 dataset in the CUDA environment to create reconstructed images. By Dr. Vaibhav Kumar The Autoencoders, a variant of the artificial neural networks, are applied very successfully in the image process especially to reconstruct the images.

Building the autoencoder¶. In general, an autoencoder consists of an encoder that maps the input to a lower-dimensional feature vector , and a decoder that reconstructs the input from .We train the model by comparing to and optimizing the parameters to increase the similarity between and .See below for a small illustration of the autoencoder framework.

where ⋆ \star ⋆ is the valid 2D cross-correlation operator, N N N is a batch size, C C C denotes a number of channels, H H H is a height of input planes in pixels, and W W W is width in pixels.. This module supports TensorFloat32.. stride controls the stride for the cross-correlation, a single number or a tuple.. padding controls the amount of padding applied to the input.

Module):. def __init__(self):. super(autoencoder, self).__init__(). self.encoder = nn.Sequential(. nn.Conv2d(1, 16, 3, stride=3, padding=1), # b, 16, 10, 10.
