Webb7 feb. 2024 · We present a novel masked image modeling (MIM) approach, context autoencoder (CAE), for self-supervised representation pretraining. The goal is to pretrain an encoder by solving the pretext task: estimate the masked patches from the visible patches in an image. Our approach first feeds the visible patches into the encoder, extracting the … Webb11 apr. 2024 · 代理任务（pretext task）很好地解决了这个问题，是对比学习成为无监督学习方法的不可或缺的保证。代理任务是一种为达到特定训练任务而设计的间接任务，代理任务并非人们真正感兴趣的任务，即不是分类、分割和检测任务，这些有具体应用场景的任务，其主要目的是让模型学习到良好的数据表示。
