Training a vanilla GAN requires a large number of samples and a significant amount of time. However, in practical applications, obtaining a large dataset and dedicating extensive time to model training can be very costly. Training a GAN with a small number of samples to generate high-quality images is a pressing research problem. Although this area has seen limited exploration, FAML (Fast Adaptive Meta-Learning) stands out as a notable approach. However, FAML has the following shortcomings: (1) The training time on complex datasets, such as VGGFaces and MiniImageNet, is excessively long. (2) It exhibits poor generalization performance and produces low-quality images across different datasets. (3) The generated samples lack diversity. To address the three shortcomings, we improved FAML in two key areas: model structure and loss function. The improved model effectively overcomes all three limitations of FAML. We conducted extensive experiments on four datasets to compare our model with the baseline FAML across seven evaluation metrics. The results demonstrate that our model is both more efficient and effective, particularly on the two complex datasets, VGGFaces and MiniImageNet. Our model outperforms FAML on six of the seven evaluation metrics, with only a slight underperformance on one metric.

The task is decomposed into measurements of parallel straight line and parallel curve structures due to the inherent geometric differences between them, where the parallelism between curve structures can be further transformed into a matching problem. For parallel straight lines, the angle constraints and the rate of overlapping projection are considered as the parallel relationship selection rules for the candidate lines. For the parallel curves, the approximate vertical growing (AVG) algorithm is proposed to accelerate the search of adjacent curves and each smooth curve is coded as a vector with different angle values. The matching pairs are extracted through cosine similarity transformation and convexity consistency. Finally, the parallel curves are extracted by a decision-making process.

Adaptive multiscale feature pyramid enhancement modules (AMFPEM) are inserted in the feature fusion stage between both Swin Transformer and Vision Longformer to learn the relationship between object scale variation and enhance the feature representation capacity of small objects. In this way, the accuracy of urban scene detection is significantly improved, and weak aggregated objects are successfully detected from UAV images.

In distributed machine learning environments however, individual AI agents are merely part of a system where decisions are made in a centralized and aggregated fashion or require a fixed network topology, a practice prone to security risks and collaboration is nearly absent. For instance, Byzantine Failures may tamper both the training and inference stage of individual AI agents, leading to significantly reduced overall system performance. Inspired by societal practices, we propose a decentralized inference strategy where each individual agent is empowered to make their own decisions, by exchanging and aggregating information with other agents in their network. To this end, a “Quality of Inference” consensus protocol (QoI) is proposed, forming a single commonly accepted inference rule applied by every individual agent. The overall system knowledge and decisions on specific manners can thereby be stored by all individual agents in a decentralized fashion, employing e.g., blockchain technology.

However, deep feature-based correlation filters are affected by undesired boundary effects, which reduce the tracking performance. Moreover, the tracker moves towards a region that is identical to the target due to the sudden variation in target appearance and complicated background areas. To overcome these issues, we propose an adaptive spatially regularized target attribute-aware background suppressed deep correlation filter (ASTABSCF). To do this, a novel adaptive spatially regularized technique is presented, which aims to learn an efficient spatial weight for a particular object and fast target appearance variations. Specifically, we present a target-aware background suppression method with dual regression approach, which utilizes a saliency detection technique to produce the target mask. In this technique, we employ the global and target features to get the dual filters known as the global and target filters. Accordingly, global and target response maps are produced by dual filters, which are integrated into the detection stage to optimize the target response. In addition, a novel adaptive attribute-aware approach is presented to emphasize channel-specific discriminative features, which implements a post-processing technique on the observed spatial patterns to reduce the influence of less prominent channels. Therefore, the learned adaptive spatial attention patterns significantly reduce the irrelevant information of multi-channel features and improve the tracker performance.

First, the CIELab map, gradient feature map, and Mean Subtracted Contrast Normalized feature map of the underwater image are obtained. Then, these feature maps are divided into non-overlapping 32x32 patches, and each patch is fed into the corresponding sub-network. This method allows for a comprehensive description of the changes in visual and structural information resulting from quality degradation in underwater images. Subsequently, the features extracted by the multipath network are fused using a feature fusion network to promote feature complementarity and overcome the limitations of individual features. Finally, the relationship between underwater image quality and fusion features was learned to obtain an evaluation model. Furthermore, the quality of the underwater image can be measured by combining the quality prediction scores of different patches. Experimental results on underwater image datasets demonstrate that the proposed method can achieve more accurate and stable quality measurement results with a more lightweight structure.
