WebAug 21, 2024 · In this work, we revisit the weak-to-strong consistency framework, popularized by FixMatch from semi-supervised classification, where the prediction of a weakly perturbed image serves as supervision for its strongly perturbed version. Intriguingly, we observe that such a simple pipeline already achieves competitive results against … Webdirectly. Besides, mean-teacher employs a consistency regularization to encourage similar predictions from the teacher and the student model. FixMatch [7] assumes that the consistency should also hold between images applied with augmentations of different degrees, and applies both a weak and a strong set of data augmentations. tsp by age

Revisiting Weak-to-Strong Consistency in Semi-Supervised …

WebFixMatch utilizes such consistency regularization with strong augmentation to achieve competitive performance. For unlabeled data, FixMatch first uses weak augmentation to generate artificial labels. These labels are then used as the target of strongly-augmented data.

"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. Description … " - Fixmatch mean teacher
