Skin cancer diagnosis is difficult due to lesion presentation variability. Conventionalmethods struggle to manuallyextract features and capture lesions spatial and temporal variations. This study introduces a deep learning-basedConvolutional and Recurrent Neural Network (CNN-RNN) model with a ResNet-50 architecture which usedas the feature extractor to enhance skin cancer classification. Leveraging synergistic spatial feature extractionand temporal sequence learning, the model demonstrates robust performance on a dataset of 9000 skin lesionphotos from nine cancer types. Using pre-trained ResNet-50 for spatial data extraction and Long Short-TermMemory (LSTM) for temporal dependencies, the model achieves a high average recognition accuracy, surpassingprevious methods. The comprehensive evaluation, including accuracy, precision, recall, and F1-score, underscoresthe model’s competence in categorizing skin cancer types. This research contributes a sophisticated model andvaluable guidance for deep learning-based diagnostics, also this model excels in overcoming spatial and temporalcomplexities, offering a sophisticated solution for dermatological diagnostics research.

Predicting vehicles' motion on highways has become crucial for enhancing road safety and traffic flow. Deep learning, which reached exceptional results in various applications, is now the leading approach for vehicle motion prediction. This work presents a deep learning-based model using Long Short-Term Memory (LSTM) networks to classify vehicle intentions into lane-keeping, left lane-changing, and right lane-changing. Utilizing the PREVENTION dataset, which provides naturalistic driving data, a sequence of centre points, longitudinal distances, lateral distances and yaw angles of a vehicle has been extracted to train the model to predict lane changes effectively. The model consists of three LSTM layers, a dense output layer and a drop out added between layers to prevent overfitting. Experiments focusing on optimizing the model parameters, learning rate, sequence length, and batch size, were conducted to determine their impact on prediction effectiveness. The best-performing model showed significant results in lane changing prediction, achieving an accuracy of 84%, precision of 89%, and recall of 82%. Future work will aim to train the model on more complex features, to account for vehicle inter-dependencies and interactions, and test model on various highway scenarios for a more reliable system. © 2024 IEEE.

This paper presents a comprehensive dataset of Egyptian roads integrated with chaotic scenarios captured by EGY-DRiVeS' lab golf car to aid in developing the autonomous driving experience. Using Velodyne 3D laser scanners, C922 Pro HD webcams, and iPhone 11 Pro cameras, a cumulative recording time of 3 hours and 48 minutes was documented. This included 1 hour and 15 minutes of LiDAR recordings, 1 hour and 45 minutes of camera recordings, and 48 minutes and 13 seconds of synced recordings. The dataset encompasses diverse scenarios and objects, ranging from urban environments with dynamic and static objects to rural highways. In-campus roads and intersections are also included, providing real-world scenarios such as vehicular and pedestrian behavior within campus premises. Each part of the dataset is annotated with 2D bounding boxes offering detailed information about vehicles, pedestrians and road objects. The provided data are calibrated, synchronized, and timestamped. Alongside the dataset, data format specifications, annotated data samples, and all supplementary recordings are provided upon request. © 2024 IEEE.

The study of combat system-of-systems architecture design (CSAD) is the basis of cross-domain cooperative activities, and cross-domain cooperative activities are the basis for realizing mosaic warfare. This paper proposes a mixed-integer programming model for CSAD problem-oriented mission planning and an improved evolutionary algorithm for solving the model. The goal of the CSAD problem is to design the architecture of the combat system-of-systems which is evaluated based on the performance of combat tasks. Therefore, it is necessary to model the mission planning problem, and the model should fit the characteristic of the combat system-of-systems architecture. An improved evolutionary algorithm to solve the mission planning problem is proposed. To improve the solution effect, the task planning algorithm based on predecessor strategy was designed. To further improve the performance of mission planning algorithm, an elite retention strategy was proposed, so that it can retain more good individuals and delete more poor individuals during the evolution of the algorithm, so that the solution process of the planning solution converges as soon as possible. The simulation experiments show that the proposed method can solve the CSAD problem well and has a significant improvement effect compared with the comparative neighborhood search algorithm and two heuristic algorithms. © 2022 IEEE.

With the amazing development of deep learning, more and more research apply it to the field of computer vision in recent years. However, most object detection networks are difficult to apply in our real life because of the complex structures and numerous parameters. So, it is meaningful to focus our attention on designing some lightweight network architecture in the future. In this paper, we will propose a new convolutional neural network that named M2I3-SSD (MobileNetV2-InceptionV3 Single Shot MultiBox Detector) and its variant named M2I3R-SSD (MobileNetV2-InceptionV3-NoRelu6 Single Shot MultiBox Detector) to detect the surface defection of the hot-rolled steel strip. Then fine-tune as a transfer learning method was used in our paper to reduce the overfitting problem caused by small database. And we do a lot of experiments to verify the performance about the proposed model in the end. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
