Object detection is an important aspect for autonomous driving vehicles (ADV), which may comprise of a machine learning model that detects a range of classes. As the deployment of ADV widens globally, the variety of objects to be detected may increase beyond the designated range of classes. Continual learning for object detection essentially ensure a robust adaptation of a model to detect additional classes on the fly. This study proposes a novel continual learning method for object detection that learns new object class(es) along with cumulative memory of classes from prior learning rounds to avoid any catastrophic forgetting. The results of PASCAL VOC 2007 have suggested that the proposed ER method obtains 4.3% of mAP drop compared against the all-classes learning, which is the lowest amongst other prior arts.

Deep learning models have revealed outstanding performance on image classification and object detection tasks. However, there is a crucial drop in performance when they are subject to learn new data incrementally in the absence of previous training data. They suffer from catastrophic forgetting—abrupt drop in performance. This phenomenon affects the implementation of artificial intelligence in practical scenarios. To overcome catastrophic forgetting, the previous method has either saved previous data in memory or generated the previous data. However, these methods are computationally complex and infeasible for real-time applications. In this article, we proposed the YOLOv3 as an object detection framework for incremental learning. A knowledge distillation loss is introduced for the prediction of previously learned knowledge without utilizing previous training data. Consequently, these predictions are updated while learning the current model. Experimental results on the Pascal VOC2007 indicate that the proposed method significantly improved the mean average precision up to 74% for two classes in comparison to the state-of-the-art methods.

On-road object detection is a critical component in an autonomous driving system. The safety of the vehicle can only be as good as the reliability of the on-road object detection system. Thus, developing a fast and robust object detection algorithm has been the primary goal of many automotive industries and institutes. In recent years, multi-purpose vision-based driver assistance systems have gained popularity with the emergence of a deep neural network. A monocular camera has been developed to locate an object in the image plane and estimate the distance of the said object in the real world or the vehicle plane. In this work, we present a monocular 3D object detection method that utilizes the discrete depth and orientation representation. Our proposed method strives to predict object locations on 3D space utilizing keypoint detection on the object's center point. To improve the point detection, we employ center regression on the objects segmentation mask, reducing the detection offset significantly. The simplicity of our proposed network architecture and its one-stage approach allows our algorithm to achieve competitive speed compared with prior methods. Our proposed method is able to achieve 26.93% detection score on the Cityscapes 3D object detection dataset, outperforming the preceding monocular method by a margin of 2.8 points.

The Internet of Medical Things (IoMT) has become a novel paradigm for real-time healthcare applications. Artificial intelligence (AI) based efforts have been made to address the security challenges of IoMT, the problem of imbalance data still exists, due to which AI algorithms cannot sufficiently learn malicious traffic behavior and fail to identify rare anomalies in imbalance data accurately. Therefore, in this article, we propose an intelligent model based on software defined networking and deep learning (DL) to handle the heterogeneous, complex, and distributed architecture. To tackle the imbalance challenge, the proposed model utilizes generative adversarial network (GAN) to generate plausible synthetic data for minor class traffic. It combines autoencoder-driven DL models with reconstruction error and Wasserstein distance-based GAN. When compared to naive and advanced techniques, the proposed model produced noticeably better results on an imbalance dataset and outperformed these techniques by 4.78% and 4.54% in terms of accuracy and F1-score values, respectively.

The convergence of the Internet of Things (IoT) and software-defined networking (SDN) has paved the way for a new technological paradigm in Healthcare Industry 5.0. This integration addresses the complexity, heterogeneity, and dynamic nature of smart IoT devices within healthcare systems. However, it also increases the risk of cyberattacks, particularly Distributed Denial of Service (DDoS) attacks, which pose significant threats to such critical infrastructure. While deep learning (DL)-based intrusion detection methods have demonstrated high accuracy in detecting these attacks, their opaque decision-making process often leads to their characterization as black-box models, limiting their practical use for security analysts. To overcome these challenges, this study proposes an explainable hybrid model for DDoS attack detection in SDN-IoT-based Healthcare Industry 5.0 environments. The model combines the strengths of convolutional neural networks (CNNs) for spatial feature extraction and long short-term memory (LSTM) networks for capturing temporal dependencies in network traffic. Implemented using an SDN controller, the model accurately classifies DDoS and IoT attacks while providing transparency through the shapley additive explanation (SHAP) method, which identifies the most influential features in the model’s decision-making process. Simulation results on the CICDDoS2019 and IoT Healthcare Security datasets demonstrate the model’s effectiveness, achieving detection accuracy of 99.59% and 98.12%, respectively. These findings confirm the robustness of the proposed hybrid model compared to state-of-the-art methods for detecting potential attacks in Healthcare Industry 5.0 systems.
