This excellent method is widely used in various industrial production and commercial deployments, particularly in cloud-based inference services. With the increasing demand for low-latency services, researchers are more focused on the execution efficiency of these models, especially device utilization. It is highly desirable to fully utilize GPU resources by multiplexing different inference tasks on the same GPU through device-sharing techniques such as Multiprocessing Services (MPS). However, we find it struggling when applying MPS to cascade neural networks consisting of multiple related submodels. These difficulties arise primarily from the early-exit mechanism and the execution order of the submodels. To address these obstacles, we analyzed the characteristics of cascade neural networks and combined them with device-sharing optimization techniques. Our findings indicate that improving the efficiency of cascade models through device sharing requires a balance between the gains from sharing devices and the potential wastage of computation resources due to the early-exit mechanism.</div><div>Based on our analysis, we proposed ESCAN, a GPU-sharing optimization framework for online inference of cascade neural networks. This framework includes exit-ratio-aware batch-parallel execution strategies and the corresponding resource allocation algorithms, all integrated into PyTorch. Experiments show that ESCAN improves inference efficiency by an average of 19.53% compared to the execution strategy with all cascade submodels running in parallel. Additionally, ESCAN significantly improves the efficiency of searching for computation resource allocation schemes. ESCAN optimizes the utilization of computational resources through effective GPU-sharing, greatly enhancing the efficiency of online inference for cascade models.

However, the prevalence of noisy-labeled samples can cause irreversible impairment to the generalization of models. Existing approaches have attempted to mitigate the impact of noisy labels by exploiting the different loss or confidence distributions between clean and noisy data to detect and correct noisy labels. This paper investigates the noise-induced distorting effect on foreground localization by tracking the model’s spatial attention distribution on visual activation maps. We observe that in clean samples, highly responsive regions usually focus on label-relevant foreground regions, whereas in noisy data, the model accidentally attends to uninformative background regions or cluttered object edges due to interference from label noise. Inspired by the observations, we propose a novel two-stage foreground localization-augmented noisy label learning framework named FLSC to concurrently boost the accuracy of sample selection and label correction for robust training. Specifically, FLSC first quantifies noise-induced distortion in foreground localization to foster conventional loss-based selection criteria by calculating the information reduction when deriving the foreground images from the original images based on the attention distribution. Next, we propose a noise-adaptive adversarial erasing strategy, which suppresses background activation by imposing adaptive erasure regularization, to eliminate overfitting to noisy samples while enhancing the learning of robust representations. To the best of our knowledge, it is the first attempt to exploit localization quality evaluation based on feature activation to address the label noise problem. Extensive experiments on synthetic and real-world datasets validate the superior performance of FLSC compared to state-of-the-art methods.</div></div>","PeriodicalId":49763,"journal":{"name":"Neural Networks","volume":"191 ","pages":"Article 107712"},"PeriodicalIF":6.0,"publicationDate":"2025-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144365715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In other words, they do not leverage the mutual guidance between different regions of different modalities. To address this limitation, we propose a novel RGBT tracking network, MGNet, which employs dual-stage attention and multi-scale feature fusion. The network includes the Cross-modality Cross-region Dual-stage Attention (CCDA) module and the Multi-scale Intra-region Feature Fusion (MIFF) module. The CCDA module processes features in two stages to preserve the unique features of identical region of different modalities, and then achieves mutual guidance across them. Specifically, in the first stage, features from different regions of different modalities are combined into a mixed representation, maintaining the distinct features of each region. In the second stage, attention mechanisms are applied to the mixed representation, facilitating cross-modality cross-region mutual guidance. Additionally, the MIFF module can perceive feature changes at multiple scales, ensuring effective fusion within each region.

Leveraging its powerful distribution expression capabilities, the diffusion model has been widely adopted as a type of policy in offline reinforcement learning. However, sampling a single action from diffusion policy necessitates a multi-step denoise process, which results in slow decision-making speed and poses challenges for application in real-time control tasks. Inspired by the teacher–student mechanism in human learning, this paper proposes a diffusion policy distillation (DPD) framework, which employs a deterministic policy to distill the target policy induced by the diffusion model. Although the deterministic policy cannot express the complex behavior policy induced by the empirical dataset properly, it can effectively learn a relevant target policy. Moreover, since the distillated deterministic policy is one-step, it avoids the need for iterative denoising, thereby inheriting the performance of the target policy while effectively improving the decision-making speed. DPD is plug-and-play and thus can be combined with offline reinforcement learning methods based on diffusion policy.
