WebJan 17, 2024 · FixMatch simplified SSL and obtained better classification performance by combining consistency regularization with pseudo-labeling. For the same unlabeled image, FixMatch used the weakly augmented samples to generate pseudo labels and fed strong-augmented images into the model for training. ... And we set the EMA decay rate as … WebFixMatch is an algorithm that first generates pseudo-labels using the model's predictions on weakly-augmented unlabeled images. For a given image, the pseudo-label is only retained if the model produces a high-confidence prediction. The model is then trained to predict the pseudo-label when fed a strongly-augmented version of the same image. northern pike in missouri
