Agriculture plays a vital role in providing food to a growing world population. However, plant diseases and pests result in 50% reductions in crop yields, which exacerbates poverty and threatens a sustainable food system. Currently, plant disease detection mainly relies on manual visual inspection and analysis of the field, which is a time-consuming and unreliable method. Modern technology, such as smart agriculture, can leverage machine learning, computer vision, and remote sensing technologies to overcome the limitations of traditional methods. Several machine learning algorithms have been used for plant disease classification and detection. However, these models suffer from limitations such as dependence on complex hand-crafted features for classification, and limited adaptability to new data. Deep learning models, on the other hand, have the ability to automatically learn hierarchical representations from raw data, making them inherently more informative and adaptable to changing data patterns. While existing deep learning approaches for plant disease detection have achieved some degree of success, these models still face challenges in achieving superior performance due to similar visual appearances of different plant diseases, intra-class differences, and variation in scale and resolution. To address these challenges, we proposed a framework that consists of hybrid network and attention module. Our hybrid module combines the benefits of DenseNet and InceptionNet to capture multi-scale features, while the attention module addresses the challenges of inter-class similarity and intra-class variability by isolating the most discriminative feature and disregarding extraneous and insignificant information. We performed experiments on publicly available challenging dataset. From Experimental results, we demonstrate the effectiveness of the proposed framework in achieving high accuracy in plant disease detection. © The Author(s), under exclusive licence to Springer Sci

Deep learning methods have played a prominent role in the development of computer visualization in recent years. Hyperspectral imaging (HSI) is a popular analytical technique based on spectroscopy and visible imaging which examines the pattern of light in a target and recognizes objects based on varying spectral properties. However, in remote sensing, detecting surface material via HSI analysis is a critical and difficult task. The performance of spectral-spatial data exploitation is well established to outperform typical spectral pixel-wise techniques. Because of its great feature extraction ability, convolutional neural networks (CNN) have emerged as a potent deep learning approach. CNN translates the input features of an image into an equivalent CNN feature map, in addition to naturally combining spectral and spatial information. However, spectral-spatial properties when combined with pixel-wise extraction can learn more minute details of objects present on the earth’s terrain. In this paper, a noble Composite Spectral Spatial Pixel CNN model for the classification of hyperspectral data is presented which is an amalgamation of 3D-2D-1D CNN. While the 3D and 2D CNN exploit the spectral-spatial features effectively, 1D CNN works on pixel-wise feature extraction. Further, to optimize the classification performance of the proposed model, a new hybrid activation function Flatten-T Swish is also used which is the combination of ReLU and Swish function. The proposed model is compared with other state-of-the-art models based on three popular HSI datasets, and it is found that the proposed model performs better among others in terms of classification and computation time, giving 98.87% accuracy for Indian Pines, 99.92% accuracy for Pavia University, and 99.99% accuracy for Salinas Valley dataset. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2024.

Machine learning models are the backbone of smart grid optimization, but their effectiveness hinges on access to vast amounts of training data. However, smart grids face critical communication bottlenecks due to the ever-increasing volume of data from distributed sensors. This paper introduces a novel approach leveraging Generative Artificial Intelligence (GenAI), specifically a type of pre-trained Foundation Model (FM) architecture suitable for time series data due to its efficiency and privacy-preserving properties. These GenAI models are distributed to agents, or data holders, empowering them to fine-tune the foundation model with their local datasets. By fine-tuning the foundation model, the updated model can produce synthetic data that mirrors real-world grid conditions. The server aggregates fine-tuned model from all agents and then generates synthetic data which considers all data collected in the grid. This synthetic data can be used to train global machine learning models for specific tasks like anomaly detection and energy optimization. Then, the trained task models are distributed to agents in the grid to leverage them. The paper highlights the advantages of GenAI for smart grid communication, including reduced communication burden, enhanced privacy through anonymized data transmission, and improved efficiency and scalability. By enabling a distributed and intelligent communication architecture, GenAI introduces a novel way for a more secure, efficient, and sustainable energy future. © 2024 The Authors

The COVID-19 pandemic has affected millions of people globally, with respiratory organs being strongly affected in individuals with comorbidities. Medical imaging-based diagnosis and prognosis have become increasingly popular in clinical settings for detecting COVID-19 lung infections. Among various medical imaging modalities, ultrasound stands out as a low-cost, mobile, and radiation-safe imaging technology. In this comprehensive review, we focus on AI-driven studies utilizing lung ultrasound (LUS) for COVID-19 detection and analysis. We provide a detailed overview of both publicly available and private LUS datasets and categorize the AI studies according to the dataset they used. Additionally, we systematically analyzed and tabulated the studies across various dimensions, including data preprocessing methods, AI models, cross-validation techniques, and evaluation metrics. In total, we reviewed 60 articles, 41 of which utilized public datasets, while the remaining employed private data. Our findings suggest that ultrasound-based AI studies for COVID-19 detection have great potential for clinical use, especially for children and pregnant women. Our review also provides a useful summary for future researchers and clinicians who may be interested in the field. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2025.

The intelligent use of artificial intelligence-generated content (AIGC) in magnetic resonance imaging (MRI) analysis is a significant step towards the rapidly advancing field of consumer electronics (CE) used in healthcare. It greatly improves the accuracy and usefulness of diagnostic processes. This paper introduces a novel MRI analysis approach through the lens of AIGC, leveraging physics-informed deep learning (PIDL) models. This integration pioneers a new paradigm in consumer healthcare diagnostics and embeds physics principles into deep learning (DL) models, thus improving interpretability and adherence to physical constraints. Additionally, this method improves the visibility of the healthcare community by integrating explainable AI (XAI) techniques, including gradient-weighted class activation mapping (Grad-CAM) and Local Interpretable Model-Agnostic Explanations (LIME). This approach demonstrates a reasonable precision rate of 96% when applied to brain tumor MRI images. Therefore, this research introduces a new para diagram of applying AIGC in medical imaging analysis within Consumer Healthcare Electronics (CHE). IEEE

Detecting Low-Yield Machines in Batch Production Systems Based on Observed Defective Pieces

引用

IEEE Transactions on Systems, Man, and Cybernetics: Systems 2024年第7期54卷 3972-3983页

作者： Adipraja, Philip F. E. Chang, Chin-Chun Yang, Hua-Sheng Wang, Wei-Jen Liang, Deron National Central University Department of Computer Science and Information Engineering Taoyuan City32001 Taiwan National Taiwan Ocean University Department of Computer Science and Engineering Keelung City20224 Taiwan

In batch production systems, detecting low-yield machines is essential for minimizing the production of defective pieces, which is a complex problem that currently requires multiple experts, considerable capital, or a combination of both to overcome. To solve this problem, we proposed a cost-efficient and straightforward method that involves using maximum likelihood estimation and bootstrap confidence intervals to estimate per-machine yield;this method enables identification of low-yield machines and generation of a list of these machines. Manufacturing engineers can use the list to perform necessary verification and maintenance processes. Before implementing this method, a manufacturer with 50-500 machines should build a dataset containing approximately 6-20 times as many batches as there are production machines. When this condition is met, the proposed method can be used effectively to detect up to five low-yield machines. © 2013 IEEE.

The UAV-assisted wireless network is envisioned as a key player in the sixth generation (6G) wireless systems. One of the most challenging tasks to make it practically viable is to deploy UAVs considering user density, propagation environment and other factors. In traditional UAV deployment techniques, the propagation environment is hardly considered. In this paper, we propose an algorithm for deploying UAVs considering both factors in order to maximise the user throughput using the Whale Optimisation Algorithm (WOA). We formulate the UAV deployment problem as a global optimisation problem. Then, we formulate the objective function to maximise the average user throughput while satisfying several constraints. Through simulations, we show that the proposed technique outperforms the state-of-the-art UAV deployment algorithms. Up to 36% gain in the average user throughput is obtained. The proposed technique is capable of deploying the UAVs to support a certain level of minimum average user throughput requirement. Copyright © 2024 Inderscience Enterprises Ltd.
