Linear projection of flattened patches 翻译
Nettet19. des. 2024 · 将 patch 输入一个 Linear Projection of Flattened Patches 这个 Embedding 层,就会得到一个个向量,通常就称作 token。 紧接着在一系列 token 的前面加上加上一个新的 token(类别token,有点像输入给 Transformer Decoder 的 START,就是对应着 * 那个位置),此外还需要加上位置的信息,对应着 0~9。 http://www.dermatology.org/morphology/patch1.htm
