    A Graph Convolutional Network for Visual Categorization
    (Springer, 2024-10) Bera, Asish; Hazra, Arnab
    The Convolutional Neural Networks (CNNs) have attained enhanced performance over conventional feature descriptors for image classification. Recently, Graph Convolutional Networks (GCNs) have also been witnessed in achieving improved performances for visual classification in various domains. A typical GCN is pertinent for propagating deep features using graph-based message passing methods. There are several domains such as the disease diagnosis of humans and plants where GCN could be explored for further performance enhancement. Thus, ample research attention is essential for solving different kinds of visual classification problems. In this direction, this work integrates the benefits of CNN and GCN for improving the feature representation by building a spatial relation using a GCN. In this work, a simple deep learning model is proposed that extracts the high-level deep features using a backbone CNN. Then, a GCN is applied for enhancing feature representation capabilities further for image classification. The proposed method has achieved improved performances on seven benchmark public datasets representing dance postures, hand shapes, agriculture, medical imaging, and aerial scene classification. The proposed method is developed using four different CNN backbones. Particularly, the proposed method based on ResNet-50 backbone has attained 89.98% accuracy on Dance-12, 90.34% accuracy on REST hand shape, 94.06% accuracy on Kvasir, and 75.89% accuracy on ISIC skin cancer, 91.73% accuracy on AID aerial scene classification, and 95.24% accuracy on PlantPathology datasets.

    Role of machine learning and deep learning in securing 5G-driven industrial IoT applications
    (Elsevier, 2021-12) Chamola, Vinay; Gupta, Shashank
    The Internet of Things (IoT) connects millions of computing devices and has set a stage for future technology where industrial use cases like smart cities and smart houses will operate with minimal human intervention. IoT’s cross-domain amalgamations with emergent technologies like 5G and blockchain affects human life. Hence, increase in reliance over IoT necessitates focus on its privacy and security concerns. Implementing security through encryption, authentication, access control and communication security is the need of the hour. These needs can be best catered with the use of machine learning (ML) and deep learning (DL) that can help in realizing secure intelligent systems. In this work, the authors present a comprehensive review for securing Industrial-IoT (I-IoT) devices to contribute to the development of security methods for I-IoT deployed over 5G and blockchain. The survey provides a general analysis of the state-of-the-art security implementation and further assesses the product life cycle of IoT devices. The authors present numerous virtues as well as faults in the machine learning and deep learning algorithms deployed over the fog architecture in context with the security solutions. The potential security algorithms can help overcome many challenges in the IoT security and pave way for implementation with emerging technologies like 5G, blockchain, edge computing, fog computing and their use cases for creating smart environments.
