Webb31 aug. 2024 · 作者提出了一种猜想： SimSiam实际上是一种Expectation-Maximization（EM）的算法。 ——最大期望算法。我们最熟悉的最大期望算法就是k-means算法。（公式1）这里是输入图像，是图像的一种增强，是encoder，不一定局限于图像的representation，在训练网络时我们希望找到一个，找到一个，是的loss的期 … WebbSimSiam (Simple Siamese Representation Learning) SimSiam简单用一句话描述就是没有momentum encoder的BYOL。 BYOL拿掉了MoCo的memory bank，SimSiam进一步地拿掉了momentum encoder。方法简单，实务上同样能避免collapsing output的发生。 SimSiam的架构与BYOL一样是三个阶段的架构，先过主网络embedding，再过小网 … chromium source code readingWebb7 dec. 2024 · SimSiam簡單用一句話描述就是沒有momentum encoder的BYOL。 BYOL拿掉了MoCo的memory bank，SimSiam進一步地拿掉了momentum encoder。方法簡單，實務上同樣能避免 ... chromium source

"Webb2 jan. 2024 · SimSiam的理论解释意味着带stop-gradient的孪生网络表征学习都可以用EM算法解释。 stop-gradient起到至关重要的作用，并且需要一个预测期望E的方法进行辅助使用。但是SimSiam仍然无法解释模型坍塌现象，SimSiam以及它的变体不坍塌现象仍然是一个经验性的观察，模型坍塌仍然需要后续的工作进一步讨论。看懂了SimSiam对孪生网络 … " - Simsiam github
