【Semi-supervised Learning】Mean Teacher - 知乎 - 知乎专栏
WebThat is, after each training step, update the teacher weights a little bit toward the student weights. Our contribution is the last step. Laine and Aila used shared parameters between the student and the teacher, or used a temporal ensemble of teacher predictions. In comparison, Mean Teacher is more accurate and applicable to large datasets. WebOct 8, 2024 · It consists of the following steps: Take a supervised architecture and make a copy of it. Let's call the original model the student and the new one the teacher. At each training step, use the same minibatch as inputs to both the student and the teacher but add random augmentation or noise to the inputs separately. table of scales
