Task assignment is a fundamental problem in spatial crowdsourcing. In many spatial crowdsourcing platforms, such as Didi, AMAP, and Uber, there are hybrid tasks, including real-time and reservation-type tasks, which are with different constraints and unevenly distributed in spatial and temporal. For these hybrid tasks, most existing studies suffer from low task completion rate and low profit for two reasons: firstly, they focus on homogeneous tasks with uniform constraints, and assign hybrid tasks separately;secondly, they cannot effectively address the uneven distribution of hybrid tasks. Inspired by this, we delve into the problem of online hybrid task assignment (HyTAO) with the goal of maximizing total revenue by simultaneously assigning both real-time and reservation-type tasks online for the first time. We prove the NP-hardness of the offline version of the HyTAO problem. To solve HyTAO effectively, we utilize a cross-platform cooperation model to tackle the challenge of non-uniform distribution. Following this, we design a binary tree-based search algorithm, namely BTS, which is capable of uniformly processing various types of tasks and quickly searching for available workers. Additionally, we discuss the parallel optimization strategies of BTS. To further enhance performance, we develop TBTS, which identifies tasks with high increased revenue based on a threshold. Finally, we conduct a comprehensive analysis of the complexity and competitive ratio of both BTS and TBTS. Extensive experiments are performed to demonstrate the efficiency of our approaches. © 2024 IEEE.

Due to the diversity of edge devices and applications, edge systems are heterogeneous and have been applied in artificial intelligence fields such as smart factories and intelligent transportation, which is called heterogeneous edge intelligence. Many studies employ computation offloading to transfer processing data from resource-scarce edge devices to resource-rich edge servers. These studies primarily focus on the overall resource consumption of homogeneous edge systems, neglecting the system heterogeneity and the details of resource consumption. In this article, we construct a system model from a parallel perspective for the heterogeneous edge system with different processors, memory, and applications, which perceives the cost of energy and delay from three levels: system, application, and component. A hybrid metaheuristic algorithm combined with a greedy rule, hybrid mutation, and whale optimization algorithm (GHMWOA) is proposed to realize partial computation offloading. A partial offloading architecture of heterogeneous edge intelligence is proposed to validate our model and algorithm with real-world hardware and software. Experiment results not only show GHMWOA outperforms multiple classical optimization algorithms in minimizing energy consumption, but also discover on which system component energy consumption depends, and how properties of application and system influence the cost of energy. © 2014 IEEE.

The study highlights the importance of facial landmark trajectories in understanding mental health by investigating the application of supervised learning systems to identify emotions. Diagnoses and treatment plans are impacted by the difficulty in recognizing and controlling emotions, which are intrinsically tied to mental health. Although physiological signals like ECG and EEG are accurate, they have drawbacks including expense and user discomfort. Because they are noninvasive, facial landmarks present a viable substitute for practical uses. Using information from the ASCERTAIN dataset, this study divided emotions into four valence-arousal plane quadrants: High Arousal High Valence (HAHV), High Arousal Low Valence (HALV), Low Arousal High Valence (LAHV), and Low Arousal Low Valence (LALV). Algorithms including Random Forest, K-Nearest Neighbors (KNN), Decision Tree, and Support Vector Machine (SVM) were used to solve a 4-class classification problem. A common problem, class imbalance, was lessened by employing the Synthetic Minority Oversampling Technique (SMOTE). The study showed that SMOTE greatly enhanced predictions for minority classes, particularly for LALV, whereas classifiers strongly preferred the majority class in the absence of balance. Despite possible overfitting, Decision Tree has the greatest true positive rate among classifiers for LALV after SMOTE application. The findings demonstrate developments in emotional computing and provide information for applications in mental health support and human-computer interaction. © 2025 IEEE.

Recently, there has been interest in classifying emotions using audio inputs and machine learning methods. Because a single statement might be delivered in a variety of emotional circumstances, textual data alone is insufficient for identifying the emotions, necessitating the adoption of novel feature extraction approaches. This paper aims to provide an improved framework which uses a detailed study on audio sound features like mel-frequency cepstral coefficients (MFCCs), zero crossing rate (ZCR), spectral bandwidth and many other features for audio analysis and uses the same for predicting emotions. The paper also emphasises on various audio augmentation techniques to improve the generalising power of the model. With the above-mentioned improvements in the feature vector and a carefully selected deep neural network, state-of-the-art classification accuracy is achieved on the two state-of-the-art datasets Toronto emotional speech set (TESS) and the Ryerson Audio-Visual Database of Emotional Speech and Song (RAVDESS). The paper is concluded with the improved approach for emotion recognition using audio signals and leads to future scope of efficient speech recognition applications. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

This paper presents an integrated framework for the comprehensive analysis of diseases affecting pomegranate fruit. The suggested system, which makes use of deep learning techniques, includes semantic segmentation for diseased region localization, multiclass illness classification, and image processing-based severity assessment. Initially, four common diseases - Alternaria, Anthracnose, Bacterial Blight, and Cer-cospora - are successfully identified through the use of a Convolutional Neural Network (CNN) for multiclass classification. Then, annotated photos are used as training data for Semantic Segmentation, which uses the UNet architecture to identify the unhealthy spots within the fruit. The area and percentage of the segmented region are determined, and thresholds for high, medium, and low severity levels are then defined. The segmentation results are then used as inputs for severity estimate. Early identification and intervention tactics are made easier by the severity level prediction, which is based on the proportion of the segmented region. In order to improve pomegranate fruit management methods, the suggested framework provides a thorough method of disease analysis by combining categorization, semantic segmentation, and severity prediction. © 2024 IEEE.

This research proposes an integrated framework of a digital twin, incorporating artificial intelligence and the Internet of Things to optimize energy management and prolong the lifespan of the battery in electric vehicles. Under typical operating conditions, the system exhibits predictive accuracy with mean absolute error relative to actual data equal to 0.042 and root mean square error equal to 0.055. These values reflect improvement in responsiveness of the system since latency has been reduced to 0.12 seconds with feedback response times established at 0.45 seconds. Moreover, it has increased by 15% in energy efficiency while promoting its longevity with a capacity fade rate measured at 0.0025% per cycle. Besides, the model shows strong anomaly detection capability - maintenance alert precision is found to be 95% while detection rate reaches76%. All these results point out the possibility that combining Digital Twin technology with AI and IoT may end up significantly boosting energy management systems for electric vehicles compared to more traditional approaches. © 2025 IEEE.
