WebJun 28, 2024 · In this paper, we re-think the design of the token-mixing MLP. We discover that token-mixing MLPs in existing MLP-based backbones are spatial-specific, and thus it is sensitive to spatial translation. Meanwhile, the channel-agnostic property of the existing token-mixing MLPs limits their capability in mixing tokens. WebMixer分为channel-mixing MLP和token-mixing MLP两类。channel-mixing MLP允许不同通道之间进行交流;token-mixing MLP允许不同空间位置(tokens)进行交流。这两种类型的layer是交替堆叠的,方便支持两个输入维度的交流。每个MLP由两层fully-connected和一个GELU构成。 Mixer Architecture
