The paper presents a novel approach to address the problem of lifetime maximization in Wireless Sensor Networks (WSNs) with limited initial energy constraints. The authors introduce a scheduling approach called Non-disjoint Set Cover (NDSC) and propose a method based on the Particle Swarm Optimization (PSO) algorithm to optimize the lifetime of randomly deployed WSNs. The approach involves dividing the problem into two sub-problems. The first sub-problem focuses on finding the maximum number of NDSCs that achieve full coverage of the targets in the area. PSO, using a heuristic method, is employed to address this sub-problem. The second sub-problem deals with finding an optimal scheduling approach to maximize the WSN lifetime while considering the limited initial energy reserve in each sensor. Again, PSO, based on a heuristic method, is used to tackle this sub-problem. The NDSCs obtained from the first sub-problem serve as inputs for the scheduling in the second sub-problem. The solutions obtained by the proposed NDSC-PSO method are compared with those obtained by the NDSC-GA (Genetic Algorithm) method from the literature. Additionally, the quality of the NDSC-PSO solutions is evaluated by comparing them with exact solutions obtained using an Integer Linear Programming (ILP) method from the literature. The experimental results demonstrate that the NDSC-PSO method outperforms the NDSC-GA method in terms of finding optimal solutions for the same instances. The proposed method effectively maximizes the lifetime of WSNs while considering limited initial energy constraints. The paper contributes to the existing literature by presenting a novel approach that utilizes the PSO algorithm for finding NDSCs and scheduling them in WSNs. © 2024 IEEE.

The skin acts as an important barrier between the body and the external environment, playing a vital role as an organ. The application of deep learning in the medical field to solve various health problems has generated increasing interest. The objective of this research is to create a new model using a deep network with multi-feature fusion that enables accurate identification of various skin diseases. This paper proposes a fully fused network (FFN), which includes an improved single block (ISB) and an improved fusion block (IFB) to achieve optimal performance. To implement this, a convolutional neural network-based model for multi-class recognition of skin images has been developed, in which ISB is used to segment diseases in skin images. The IFB module is designed to enhance the effectiveness of the fused network. The model is built and evaluated using our proprietary dataset (Skin_disease_v1) along with publicly available datasets, namely ISIC2016, ISIC2017, and HAM10000. The highest accuracy achieved in experiments was 86% for ISB, 90% for IFB, and 92% for FFN using HAM10000 (for ResNet101V2), HAM10000 (for Resnet50 + ResNet101V2), and HAM10000 (for Resnet50 + ResNet101V2). This shows an accuracy improvement of 9.2%, 13.2%, and 15.2% compared to the state-of-the-art ISB, IFB, and FFN approaches, respectively. Our network outperforms existing networks in terms of performance. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2024.

Enhance Dehazed Images Rapidly Without Losing Restoration Accuracy

引用

IEEE Access 2024年 12卷 40795-40808页

作者： Liu, Ping-Juei National Chin-Yi University of Technology Department of Artificial Intelligence and Computer Engineering Taichung411030 Taiwan

We proposed a novel image-enhancing framework to ensure consolidated restoration accuracy when remedying the visual quality of dehazed images, such as over-saturation, color deviation, or luminance issues. Conventionally, the dehazing process was usually considered image restoration;however, enhancement methods only aimed to improve dehazed images' contrast, brightness, and detail. Therefore, the conventional enhancing framework tended to degrade consolidated restoration accuracy due to focusing on low-level image features rather than controlling errors associated with the dehazing process. Our method aimed to improve the consolidated restoration accuracy of the dehazing-and-enhancing process. In experiments, the proposed framework improved the visual quality and preserved restoration accuracy (despite enhancements) with high computational efficiency and resolved quality issues generated by conventional dehazing algorithms. Moreover, the minimal time complexity of the proposed framework is O(n), ensuring practical applicability when implemented in conjunction with state-of-the-art dehazing algorithms. © 2013 IEEE.

Arabic Idioms Detection by Utilizing Deep Learning and Transformer-based Models 6

Arabic Idioms Detection by Utilizing Deep Learning and Trans...

6th International Conference on AI in Computational Linguistics, ACLing 2024

作者： Himdi, Hanen Computer Science and Artificial Intelligence Department College of Computer Science and Engineering University of Jeddah Jeddah Saudi Arabia

Arabic language resources and natural language processing technologies have seen significant advancements in recent years. The detection of idiomatic expressions is a crucial problem in Arabic natural language processing. Unfortunately, there have been few advancements in this field due to the scarcity of datasets and computational models that still struggle to handle Arabic idiomatic phrases. Although idioms have significance in Arabic because of their distinctive relation to history and cultural knowledge, they also offer a language tool for conveying concepts and thoughts that may diverge from their literal interpretation. Hence, to accurately detect their incongruent language, a model requires the ability to interpret the idioms' contextual meaning. To tackle this issue, this study entails comprehensive work on detecting Arabic idiomatic and literal statements. For that, we introduce a large Arabic idiomatic and literal statements. The dataset includes idioms from several Arabic idiomatic platforms balanced with literal statements from titles in news platforms with similar keywords found in the idioms. This study adopts four deep learning models, namely, CNN, LSTM, Bi-LSTM, and GRU trained with word embeddings, FastText and Skip-Gram Word2Vec, and three transformer-based models, BERT, RoBERTa, and DistilBERT were compiled and assessed via empirical evaluations. Our experiments demonstrated that transformer-based models outperformed deep learning models trained by word embedding to detect Arabic idioms and literal statements, reaching 97% in favor of DistilBERT. We also enhanced the accuracy through the ensemble stacking method, boosting it by 0.8 points. Furthermore, we propose a novel Arabic idiom interpreter that offers simple explanations for selected idiomatic contents within the literal text. Our work enriches the challenge of detecting incongruities found in similar figurative genres, specifically in the rich morphological language, Arabic. © 2024 Elsevier
