First, a random patch of the image is selected and resized to224 224 with a random horizontal flip, followed byacolor distortion, consisting ofarandom sequence ofbrightness, contrast, saturation, hue adjustments, and anoptional grayscale conversion. FinallyGaussian blur and solarization are appliedtothepatches. Optimization We use theLARS optimizer [70] with a cosine decay learning rate schedule [71], without restarts, over1000epochs, with awarm-up period of10epochs. Wesetthebase learning rate to 0.2, scaled linearly [72] with the batch size (LearningRate = 0.2 BatchSize/256). Forthetargetnetwork,the exponential moving average parameterτ starts fromτbase = 0.996and is increased to one during training.
