In recent years, we have witnessed a tremendous evolution in generative adversarial networks resulting in the creation of much realistic fake multimedia content termed deepfakes. The deepfakes are created by superimposing one person’s real facial features, expressions, or lip movements onto another one. Apart from the benefits of deepfakes, it has been largely misused to propagate disinformation about influential persons like celebrities, politicians, etc. Since the deepfakes are created using different generative algorithms and involve much realism, thus it is a challenging task to detect them. Existing deepfakes detection methods have shown lower performance on forged videos that are generated using different algorithms, as well as videos that are of low resolution, compressed, or computationally more complex. To counter these issues, we propose a novel fused truncated DenseNet121 model for deepfakes videos detection. We employ transfer learning to reduce the resources and improve effectiveness, truncation to reduce the parameters and model size, and feature fusion to strengthen the representation by capturing more distinct traits of the input video. Our fused truncated DenseNet model lowers the DenseNet121 parameters count from 8.5 to 0.5 million. This makes our model more effective and lightweight that can be deployed in portable devices for real-time deepfakes detection. Our proposed model can reliably detect various types of deepfakes as well as deepfakes of different generative methods. We evaluated our model on two diverse datasets: a large-scale FaceForensics (FF)++ dataset and the World Leaders (WL) dataset. Our model achieves a remarkable accuracy of 99.03% on the WL dataset and 87.76% on the FF++ which shows the effectiveness of our method for deepfakes detection. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

With the development of IoT technology, a significant amount of time series data is continuously generated, and anomaly detection of this data is crucial. However, time series data in IoT is dynamic and heterogeneous, and most centralized learning also suffers from security and privacy issues. To address these issues, we propose a multi-task anomaly detection approach based on federated learning (MTAD-FL) to address these problems. First, we propose a distributed framework based on Multi-Task Federated Learning (MT-FL), which aims to solve multiple tasks simultaneously while exploiting similarities and differences between tasks;second, to identify complex anomaly patterns and features in the IoT environment, we construct a Squeeze Excitation (SE) based and External Attention (EA) based Enhance Dual Network (SE-EA-EDN) feature extractor to monitor real-time data features from IoT systems efficiently;finally, we design a Local-Global Feature-based Parallel Knowledge Transfer (LGF-PKT) to parallelize the updating of weights of local and global features. To validate the effectiveness of our approach, we conducted comparative experiments on three publicly available datasets, SMD, SWaT, and SKAB, and MTAD-FL improved F1 by 11%, 67.8%, and 27.5%, respectively, over the other methods. © ICST Institute for computer Sciences, Social Informatics and Telecommunications engineering 2024.

Concept drift refers to the probability distribution of data generation changes over time in a data stream environment. In recent years, there has been an increasing interest in drift detection models. However, due to the lack of labeled concept drift datasets, most researchers tend to using synthetic drift data generators for model training. These generators only have relatively simple feature distributions, which fail to capture the complexity found in real-world scenarios. This paper introduces a real scenario concept drift label generator (RealDriftGenerator). This generator aims to preserve the complexity and temporal correlation of real-world scenario while generating concept drifts with user defined drift positions and drift widths. The validation result show that the temporal correlation coefficients of RealDriftGenerator is significantly higher than benchmark drift generators. Additionally, the ability of RealDriftGenerator to capture the complexity in real-world scenarios is 20% higher than benchmark drift generators(measured by model performance). The source code of RealDriftGenerator has been published on https://***/sniperrifle71/realDriftGenerator. © 2024 IEEE.

This paper introduces an advanced and efficient method for distributed drone-based fruit recognition and localization, tailored to satisfy the precision and security requirements of autonomous agricultural operations. Our method incorporates depth information to ensure precise localization and utilizes a streamlined detection network centered on the RepVGG module. This module replaces the traditional C2f module, enhancing detection performance while maintaining speed. To bolster the detection of small, distant fruits in complex settings, we integrate Selective Kernel Attention (SKAttention) and a specialized small-target detection layer. This adaptation allows the system to manage difficult conditions, such as variable lighting and obstructive foliage. To reinforce security, the tasks of recognition and localization are distributed among multiple drones, enhancing resilience against tampering and data manipulation. This distribution also optimizes resource allocation through collaborative processing. The model remains lightweight and is optimized for rapid and accurate detection, which is essential for real-time applications. Our proposed system, validated with a D435 depth camera, achieves a mean Average Precision (mAP) of 0.943 and a frame rate of 169 FPS, which represents a significant improvement over the baseline by 0.039 percentage points and 25 FPS, respectively. Additionally, the average localization error is reduced to 0.82 cm, highlighting the model’s high precision. These enhancements render our system highly effective for secure, autonomous fruit-picking operations, effectively addressing significant performance and cybersecurity challenges in agriculture. This approach establishes a foundation for reliable, efficient, and secure distributed fruit-picking applications, facilitating the advancement of autonomous systems in contemporary agricultural practices.

Deep learning models are widely used in healthcare. Given the large amount of data and the need for real-time processing, running these models on IoT devices is a viable solution. This study examines the impact of deep learning models on the limited resources of IoT devices. We selected three models introduced at the 2023 CVPR conference and executed them on a Raspberry Pi with different dataset sizes to measure CPU utilization, memory utilization, and energy consumption. The results show that for the pruned Yolov5 model, CPU utilization has the strongest positive correlation with energy consumption (5.43 × 10=4 Joules), while memory utilization shows the most significant negative correlation (-4.27 × 10=4 Joules). In the FasterNet-T0 model, dataset size has the strongest positive correlation with energy consumption (2.75 × 10=5 Joules). For the Lite-Mono model, dataset size shows the most significant positive correlation (1.84 × 10=4 Joules), while memory utilization has the strongest negative correlation with energy consumption (- 2.52 × 10=4 Joules). These results highlight the key factors correlated with energy consumption across different models, providing valuable insights for deploying deep learning models on IoT devices. © 2024 IEEE.

This study utilizes the game rules of a falling-puzzle game, developed as a consumer-oriented digital game, in programming education for young people. When digital games are used in programming education, they are often designed specifically for that purpose. In this study, we focused on the game rules of the consumer falling-object puzzle game, 'Puyo Puyo.' Learning impact was investigated on 23 Japanese elementary, junior high, and senior high school students. The results show that the concepts of branching and arraying in programming were taught effectively;thus, consumer digital game rules can be used as a case study for programming education. © 2023 IEEE.
