Reprint: TransXNet: A new CNN-Transformer visual backbone that aggregates global and local information, with powerful performance!

Article address: https://arxiv.org/abs/2310.19380</code><code>Project address: https://github.com/LMMMEng/TransXNet 00 | Introduction Current situation: Recent research integrates convolutions into transformers to introduce inductive bias and improve generalization performance. (1) The static characteristics of traditional convolution make it unable to dynamically adapt to input changes, resulting in a representation difference between convolution and self-attention, because self-attention dynamically calculates the attention […]
