And Alfred’s son will not rule and Wessex will die and the Saxon will kill what he loves and the Danes will gain everything, and all will change and all will be the same as ever it was and ever will be.” Webb1 feb. 2024 · 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 representations. Then, we make predictions from visible patches to masked patches in the encoded representation space.
