Domain adaptation (DA) aims to transfer the knowledge learned from a source domain an unlabeled target domain. Some recent works tackle source-free (SFDA) where only pre-trained model is available for However, those methods do not consider keeping performance which of high practical value in real world applications. In this paper, we propose new paradigm called Generalized Source-free Adaptation (G-SFDA), needs perform well on both and domains, with access current data during adaptation....
Domain adaptation (DA) aims to alleviate the domain shift between source and target domain. Most DA methods require access data, but often that is not possible (e.g. due data privacy or intellectual property). In this paper, we address challenging source-free (SFDA) problem, where pretrained model adapted in absence of data. Our method based on observation which might no longer align with classifier, still forms clear clusters. We capture intrinsic structure by defining local affinity...
We propose a simple but effective source-free domain adaptation (SFDA) method. Treating SFDA as an unsupervised clustering problem and following the intuition that local neighbors in feature space should have more similar predictions than other features, we to optimize objective of prediction consistency. This encourages neighborhood features while farther away dissimilar predictions, leading efficient cluster assignment simultaneously. For training, seek upper-bound resulting two terms....
Background: RETFound, a self-supervised, retina-specific foundation model (FM), showed potential in downstream applications. However, its comparative performance with traditional deep learning (DL) models remains incompletely understood. This study aimed to evaluate RETFound against three ImageNet-pretrained supervised DL (ResNet50, ViT-base, SwinV2) detecting ocular and systemic diseases. Methods: We fine-tuned/trained on full datasets, 50%, 20%, fixed sample sizes (400, 200, 100 images,...

Quantum key distribution (QKD) can provide point-to-point information-theoretic secure services for two connected users. In fact, the development of QKD networks needs more focus from scientific community in order to broaden service scale technology deliver end-to-end services. Of course, some recent efforts have been made develop communication protocols based on QKD. However, due limited generation capability devices, high quantum utilization is major concern networks. Since traditional...

Domain generalization in semantic segmentation aims to alleviate the performance degradation on unseen domains through learning domain-invariant features. Existing methods diversify images source domain by adding complex or even abnormal textures reduce sensitivity domain-specific However, these approaches depends heavily richness of texture bank and training them can be time-consuming. In contrast importing arbitrarily augmenting styles randomly, we focus single itself achieve...

One of the key components within diffusion models is UNet for noise prediction. While several works have explored basic properties decoder, its encoder largely remains unexplored. In this work, we conduct first comprehensive study encoder. We empirically analyze features and provide insights to important questions regarding their changes at inference process. particular, find that change gently, whereas decoder exhibit substantial variations across different time-steps. This finding inspired...
Segmentation of multiple surfaces in medical images is a challenging problem, further complicated by the frequent presence weak boundary and mutual influence between adjacent objects. The traditional graph-based optimal surface segmentation method has proven its effectiveness with ability capturing various priors uniform graph model. However, efficacy heavily relies on handcrafted features that are used to define cost for "goodness" surface. Recently, deep learning (DL) emerging as powerful...
