Feature Guided Masked Autoencoder for Self-Supervised Learning in Remote Sensing [PDF]
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 Self-supervised learning guided by masked image modeling, such as masked autoencoder (MAE), has attracted wide attention for pretraining vision transformers in remote sensing. However, MAE tends to excessively focus on pixel details, limiting the model's
