Gaussian blur augmentation in SimCLR https://arxiv.org/abs/2002.05709

A generic data loader where the images are arranged in this way: :: root/dog/xxx.png root/dog/xxy.png root/dog/xxz.png

Build a MoCo model with: a query encoder, a key encoder, and a queue https://arxiv.org/abs/1911.05722

Horizontally flip the given PIL Image randomly with a given probability. Args: p (float): probability of the image being flipped. Default

Crop the given PIL Image to random size and aspect ratio. A crop of random size (default: of 0.08 to 1.0) of the original size and a random as

As described in the MOCO paper, there is an extra BN layer following the res5 stage.

Take two random crops of one image as the query and key.
