Mean teacher代码讲解
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. WebMean-teacher 对model parameter进行ensemble,而不是prediction ensemble,从EMA的公式上来看可以理解为momentum network,就是在momentum SGD中将gradient相关替换 …
