Cognitive Diagnosis (CD) aims to evaluate students' cognitive states based on their interaction data, enabling downstream applications such as exercise recommendation and personalized learning guidance. However, existing methods often struggle with accuracy drops in cross-domain cognitive diagnosis (CDCD), a practical yet challenging task. While some efforts have explored exercise-aspect CDCD, such as cross-subject scenarios, they fail to address the broader dual-aspect nature of CDCD, encompassing both student- and exercise-aspect variations. This diversity creates significant challenges in developing a scenario-agnostic framework. To address these gaps, we propose PromptCD, a simple yet effective framework that leverages soft prompt transfer for cognitive diagnosis. PromptCD is designed to adapt seamlessly across diverse CDCD scenarios, introducing PromptCD-S for student-aspect CDCD and PromptCD-E for exercise-aspect CDCD. Extensive experiments on real-world datasets demonstrate the robustness and effectiveness of PromptCD, consistently achieving superior performance across various CDCD scenarios. Our work offers a unified and generalizable approach to CDCD, advancing both theoretical and practical understanding in this critical domain. The implementation of our framework is publicly available at https://***/Publisher-PromptCD/PromptCD. Copyright © 2024, The Authors. All rights reserved.

Integrating Artificial Intelligence (AI) with the Internet of Things (IoT) has recently become more advantageous for various complex fields like innovative health, intrusion detection in various devices, and continuous monitoring of crops yielding in various farming lands. From the health point of view, it is essential to monitor multiple patients' health according to their abnormal health conditions. The proposed Integrated Health Monitoring System (IHMS) is developed in this work by combining AI-based models such as Recurrent Neural Networks (RNNs) and advanced IoT sensors. The IHMS is mainly used in health care applications such as heart care analysis and other abnormal health conditions like blood pressure, levels of oxygen, and glucose readings, and it transmits this information to AI-powered systems. The IHMS mainly analyzes abnormal patterns, detects anomalies, and provides timely analytical analysis of patient data. Finally, the proposed approach IHMS analyzes several datasets and shows the performance in terms of classification.

As an emerging brain-inspired computing method, hyperdimensional computing (HDC) has attracted increasing attention. HDC encodes data into a high-dimensional hypervector and makes predictions based on the similarity comparison of the hypervector. However, the computational overhead of an HDC model increases, and the accuracy decreases as the number of predicted classes increases. Branching has been proposed to address this issue in HDC models, but it also introduces a new challenge: increased memory overhead for storing new branching hypervectors. In this paper, we aim to address this issue by integrating branching with the pruning method in HDC models. To this end, we propose a simple yet effective two-level branching structure that can reduce the memory overhead required by branching hypervectors. In addition, we propose a novel variable-position pruning method capable of removing redundant dimensions from hypervectors at various positions. This can best identify the important dimensions of a hypervector and further mitigate the memory issue caused by the branching structure. Experimental results demonstrate that our two-level branching structure can slightly increase the accuracy across various datasets. With only a 0.5 % accuracy loss, our pruning method can remove more than half of the dimensions, thereby improving the HDC model's inference latency and energy consumption.

Dementia’s disease (DD) is a progressive neurological disease that primarily affects the elderly. Its primary symptom is cognitive impairment. There is currently no known cure; the only available treatments are meant to improve the patient’s quality of life. Given the challenges in treating DD, predicting its trajectory can be crucial in guiding management and treatment strategies. In this work, we propose a multimodal approach that uses MRI scans and clinical data to predict the phases of DD. The VGG19 deep learning model is utilized to interpret MRI images for image classification, and LightGBM (LGBMClassifier) is used to evaluate patient clinical data in CSV format. A multimodal deep learning technique is then used to combine the predictions from both modalities in order to increase the overall prediction accuracy. The integrated model aims to provide a comprehensive and accurate assessment of DD’s progression. This multimodal method offers a promising step toward a better understanding and management of Dementia’s disease by providing doctors with improved prediction insights into the development of the disease.

With the continuous development of human society, the global warming caused by greenhouse gas emissions is becoming more and more serious. In order to better cope with global warming, this paper uses the SARIMA model to predict global temperature. Then, SARIMA (1,1,1) (1,1,1) model is established to forecast the temperature. It is found that the temperature in 2050 and 2100 will not reach 20℃, and the global average temperature is expected to reach 20℃ in about 2180. Through model evaluation, it is found that the R-square of SARIMA model is 0.87. © 2024 SPIE.

Picking actions performed by industrial robots may be evaluated using a new architecture in this article. It has always been a goal of humankind to imbue their products with lifelike characteristics in an effort to create a substitute for themselves to carry out their commands and to work in difficult environments like the present. The most common image of a robot is that of a machine that resembles a human person in both appearance and operation. Automation is being replaced by robotics in an effort to boost output and ensure consistency in product quality. Despite the fact that every effort is being made to provide industrial robots increasingly anthropomorphic and humanlike traits and superhuman skills, today's industrial robots may not resemble humans in the slightest. A robotic manipulator, more generally known as a robotic arm, is a typical form of industrial robot. Moving joints connect stiff chains in either an open or closed kinematic structure. It is possible to think of a link's structure as a human torso with the waist, upper arm and forearm as joints [1]. The wrist joint at the end of the arm connects end effectors such as a tool and its mounting fixture, or a gripper or any other device for functioning. This workstation features a 6-axis Force/Torque pick and place robot for loading and packaging products. A six-axis Force/Torque design was used to properly evaluate and account for all of the possible loading process concerns when building the pick and place robot. © 2022 IEEE.

In this study, we outline the design and implementation of a portable massively parallel asynchronous solver for time-dependent partial differential equations (PDEs). The solver is implemented using Kokkos library for portability across different node architectures and is coupled with the communication-avoiding algorithm that relaxes the communication across nodes, thus improving the scalability. Asynchrony-tolerant finite difference schemes for spatial derivatives along with the low storage Runge-Kutta scheme for time integration are used to achieve high-order accuracy. The efficacy of the implementation is demonstrated using a mini-app that solves the three-dimensional diffusion problem.

Skin diseases rank among the most prevalent ailments in humans, which underscores the critical importance of early detection and diagnosis. Considering clinical practice, the integration of information from various modalities holds significant potential to enhance diagnostic accuracy and precision. In this study, we propose a multi-modal and multi-attention fusion network for multi-task skin disease classification. We initially devise the Shifted Window Cross-attention Fusion (SWCF) module based on the shifted window self-attention mechanism, leveraging the advantages of the attention mechanism to learn the correlations between different modalities and fully integrate multi-modal features. Subsequently, taking into account the heterogeneity of the data, we employ the Heterogeneous data Cross-attention Fusion (HDCF) module using the idea of information decoupling and separation processing to integrate image and text data. Additionally, we suggest the Dynamic Loss Weight Allocation (DLWA) method for multi-task learning to refine the training procedure. We confirm the superiority of the proposed method on the publicly available multi-modal skin lesion dataset, Derm7pt. The average accuracy of multi-modal skin disease classification is 79.14%, surpassing the current state-of-the-art methods. © 2024 IEEE.

Due to the increasing sophistication of cyber-attacks, it is more challenging to identify breaches accurately in Internet of Things (IoT). Security services like data integrity, confidentiality, and availability may become more reliable with preventive actions. Numerous substitute methods for detecting intrusions have been documented in scholarly works to tackle computer security concerns. The two main types of these technologies are anomaly-based intrusion detection systems (AIDS) and signature-based intrusion detection systems (SIDS). This survey research includes a taxonomy of current IDS, a summary of the datasets commonly used for evaluation, and a detailed examination of significant recent works. To improve computer system security, it also explains how attackers utilize evasion strategies to escape detection and looks at upcoming research challenges to oppose these techniques.

Feature-only partition of large graph data in distributed Graph Neural Network (GNN) training offers advantages over commonly adopted graph structure partition, such as minimal graph preprocessing cost and elimination of cross-worker subgraph sampling burdens. Nonetheless, performance bottleneck of GNN training with feature-only partitions still largely lies in the substantial communication overhead due to cross-worker feature fetching. To reduce the communication overhead and expedite distributed training, we first investigate and answer two key questions on convergence behaviors of GNN model in feature-partition based distribute GNN training: 1) As no worker holds a complete copy of each feature, can gradient exchange among workers compensate for the information loss due to incomplete local features? 2) If the answer to the first question is negative, is feature fetching in every training iteration of the GNN model necessary to ensure model convergence? Based on our theoretical findings on these questions, we derive an optimal communication plan that decides the frequency for feature fetching during the training process, taking into account bandwidth levels among workers and striking a balance between model loss and training time. Extensive evaluation demonstrates consistent results with our theoretical analysis, and the effectiveness of our proposed design.
