Attention Deficit/Hyperactivity Disorder (ADHD) is a highly prevalent neurodevelopmental disorder. Recent studies suggest functional brain networks could provide crucial insights for diagnosing ADHD. However, most of these studies primarily focus on functional connections, often overlooking complex higher-order spatial topological relationships among brain regions. To address this limitation, a Motifs-based Multi-scale Graph Convolution (MMGC) model is proposed to enhance feature representations by aggregating spatial features from neighboring nodes across various higher-order relationships. Our experiments indicate the effectiveness of the proposed network, achieving an average accuracy of 7 2. 0 4 %, thereby outperforming traditional brain network classification methods. © 2024 IEEE.

When the number of people increases or occlusion occurs, the human abnormal behavior detection method based on multimodal data fusion has low reliability of human behavior data information, low detection accuracy, and poor adaptability. This article used a multimodal data fusion model to solve the above problems. Mature human pose recognition technology can be used to extract human joint point data from videos. Joint coordinates can be transformed into angle and distance features of human behavior to express human posture. Machine learning methods can be applied to analyze and process joint features, obtaining data distribution features that are conducive to identifying abnormal movements. By comparing the multimodal data fusion model with other mature algorithm models, the study found that under the two evaluation methods of X-sub and X-view, the recognition accuracy of the multimodal data fusion model was 88.7% and 97.8%, respectively, which was 10.1% and 42.8% higher than the baseline method. This article identified 8 types of behaviors, among which 5 types of behaviors had an accuracy rate of over 80%, and the accuracy rate of behavior detection had all reached over 65%. Compared to other model methods, it has better practicality. © 2024 IEEE.

Hallucination detection has attracted considerable interest due to the tendency of language models to generate texts that contain hallucinations. Most existing methods start with specific local details directly extracted from text, then aggregate to form the final conclusion. However, this direct extraction approach ignores the global context, leading to isolated details, and is prone to missed or over-detections. In this paper, we present a global-to-local approach for hallucination detection (G2LDetect), which considers the global information of the text before identifying local details. We first construct a global representation of the text by transforming it into a hierarchical tree structure. Afterward, we obtain specific local details from the global tree representation using path-wise identification and perform detection on them. This global-to-local detection process ensures that local details are context-aware and complete, thus making more accurate and reliable detection results. Experimental results show that our global-to-local method outperforms existing methods, especially for longer texts. © 2025, Association for the Advancement of Artificial Intelligence (***).

Electronic Health Record (EHR) systems have replaced paper-based systems in healthcare organizations. There are now many measures in the medical field to protect sensitive big data. However, the healthcare industry is still the most affected by privacy breaches, and manipulations of fake data are endless. Content-Based Image Retrieval (CBIR) enables the retrieval of images similar to the query image and facilitates the comparison of current cases with historical cases stored in the database. This technique can find valuable applications in medical image verification, particularly in tackling the issue of counterfeit images. For image validation, we apply autoencoder to extract features, principal component analysis and genetic algorithm to optimize the extracted features, and then hand the features to vision transformer to make decisions. As a result, in comparative experiments, it is proved that our method conforms to the standard and has good performance. © 2024 IEEE.

Stability and Generalization of Asynchronous SGD: Sharper Bounds Beyond Lipschitz and Smoothness 38

Asynchronous stochastic gradient descent (ASGD) has evolved into an indispensable optimization algorithm for training modern large-scale distributed machine learning tasks. Therefore, it is imperative to explore the generalization performance of the ASGD algorithm. However, the existing results are either pessimistic and vacuous or restricted by strict assumptions that fail to reveal the intrinsic impact of asynchronous training on generalization. In this study, we establish sharper stability and generalization bounds for ASGD under much weaker assumptions. Firstly, this paper studies the on-average model stability of ASGD and provides a non-vacuous upper bound on the generalization error, without relying on the Lipschitz assumption. Furthermore, we investigate the excess generalization error of the ASGD algorithm, revealing the effects of asynchronous delay, model initialization, number of training samples and iterations on generalization performance. Secondly, for the first time, this study explores the generalization performance of ASGD in the non-smooth case. We replace smoothness with the much weaker Hölder continuous assumption and achieve similar generalization results as in the smooth case. Finally, we validate our theoretical findings by training numerous machine learning models, including convex problems and non-convex tasks in computer vision and natural language processing. © 2024 Neural information processing systems foundation.
