WebJun 7, 2024 · To address the issue, we introduce a novel incremental false negative detection for self-supervised contrastive learning. Following the training process, when … WebSelf-supervised contrastive methods [16, 6] belong to this category. In this work, we use a GAN as a novel view gen-erator for contrastive learning, which does not require a la-beled source dataset. Here, we aim at enhancing view diversity for contrastive learning via generation under the fully unsupervised set-ting.
WebMar 1, 2024 · However, two major drawbacks exist in most previous methods, i.e., insufficient exploration of the global graph structure and the problem of the false-negative samples.To address the above problems, we propose a novel Adaptive Graph Contrastive Learning (AGCL) method that utilizes multiple graph filters to capture both the local and … WebJul 14, 2024 · ISS is a self-supervised loss defined as negative cosine similarity in the framework of SimSiam, a contrastive learning method without negative pairs. I think it is a good choice because it eliminates the possibility of false negatives which might bring bias to the data. Similarly, TSS is also a self-supervised loss defined as cross-entropy ...
WebNov 15, 2024 · The existing SSCL of RSI is built based on constructing positive and negative sample pairs. However, due to the richness of RSI ground objects and the complexity of the RSI contextual semantics, the same RSI patches have the coexistence and imbalance of positive and negative samples, which causing the SSCL pushing … WebNov 15, 2024 · We propose a False negAtive sampLe aware contraStive lEarning model (FALSE) for the semantic segmentation of high-resolution RSIs. FALSE determines the approximate determination of FNS in SSCL from the perspective of the model rather than samples and mitigates the SCI in the SSCL of RSIs.
