Hybrid agent architectures enable effective control layering the agent functions according to the sophistication they require. In this study, assuming a partially observable and deterministic environment, reactive and deliberative behaviors of a hybrid scanning agent were controlled using some uninformed and informed search algorithms, respectively. As the reactive layer decided the agent actions online in an unknown environment, a map of the environment was constructed in parallel. When the reactive layer failed to find a proper action, the deliberative layer proposed a solution offline using the constructed map so that the agent could continue its scanning task. The navigation patterns that were produced with the adapted algorithms in the reactive and deliberative layers were analyzed. The results showed that depth-first search (DFS) and breadth-first search (BFS) algorithms can be used as reactive motion planners for scanning an environment in zigzag and spiral patterns. Simulations in 25 grid-based environments with different sizes and varying percentages of obstacles yielded that running A* algorithm as a deliberative planner, the agent could completely scan the environments with equal successes for all different modes of the developed scanning algorithms. The horizontal mode of the DFS-based scanning algorithm had the least rescan rate on average.

MQTT, AMQP and HTTP are messaging protocols that are commonly used for communicating with resource-constrained IoT devices. HTTP is the standard reference protocol for the REST transportation based on the request/response model, whereas both AMQP and MQTT are message-oriented protocols that use the publish/subscribe model. Message-oriented protocols enhance some of the shortcomings of the complex HTTP protocol by using asynchronous communication, changing the design from a document-centric to a data-centric approach and decreasing the header and message sizes. Although significant technical detail is present on these protocols, their real-time performance is insufficiently elaborated. In this paper, we present an experimental evaluation of these protocols conducted in a homogeneous IoT testbed using a real-time Smart City public data set. We provide the behavioral differences between messaging-based protocols and the REST-based HTTP protocol in terms of message latency and CPU usage for varying traffic loads and message sizes. The results showed that MQTT and AMQP are four times faster than HTTP protocol when comparing the message sent latencies. HTTP uses four times more CPU than the AMQP and MQTT protocols. In summary, message-oriented protocols give more stable and improved results as compared to the REST model-based HTTP protocol for all evaluation scenarios.

In this study, the Apk2Img4AndMal framework, which provides information about the application without the need for static or dynamic attributes, is recommended. The proposed framework reads APK files in binary format and converts them to grayscale images. In the classification phase of the framework, the convolutional neural network (CNN) is used, which gives successful results in image classification. In this way, the required features are obtained through a CNN. Therefore, there is also no feature extraction phase as other dynamic or static analysis-based frameworks. This property is the most important advantage of the Apk2Img4AndMal framework. The proposed framework is tested with 24588 Android malware and 3000 benign applications. The highest performance achieved in the study is up to 94%, according to the accuracy metric.

Implementing blockchain systems with less amount of decentralized computation power is a challenging task. One of the most essential solution in scaling the blockchain is selection of a trusted committee (TC). We intend to develop and apply a new method for selecting committee members depending on their reputation via particle swarm optimization (PSO) based update of the behavior of nodes. Indeed, this is the same concept as accumulating participants in the blockchain throughout the previous rounds of the consensus procedure.

The automated weed detection is an important research field in terms of agricultural productivity and economy. This study aims to apply RepVGG which is a new deep learning architecture developed on PyTorch framework and has promising results when trained and tested on ImageNet1K dataset. 920 images of the small sized Dandelion Images dataset is used for this study. Pretrained vanilla, pretrained and dropout regularized, squeeze and excitation block added and spatial attention block added versions of RepVGG are tested on the dataset. VGG16 method is also applied to the dataset and the results of the MobileNetV2 method is taken from the Kaggle Competition to get an insight about the baseline results of the classical state of the art models. The proposed RepVGG modifications could not outperform the state of the art methods on this dataset but the effect of the modifications are deeply analyzed and the best configuration is obtained by Squeeze and Excitation block added RepVGG-A0 architecture which is trained from scratch for 5 epochs and provided results of 0,875, 0,665, 0,89 and 0,74 for Accuracy, Recall, Precision and F1 metrics respectively.

DL architectures rely on extensive usage on powerful computer systems to operate in real-time. Therefore, cooperative and constructive optimizations should be made in both architecture and software parts of the related DL system. In this work, input system of the YOLO architecture is modified to accept several sources at the same time with two effective methods to increase the efficiency of the hardware system. First method is to design a scheduler which will allow YOLO architecture to process several input sources sequentially, allowing the architecture to use its full potential. Second method is to design a preprocessing algorithm to combine 4 or 9 input sources in a single input source as a 2x2 or 3x3 image matrix. In this way, YOLO architecture processes four or nine times more images in the same time, increasing its practical frame per second (FPS) value by four or nine folds. Experiment results on our machine show that the used YOLO architecture can process 3 input sources at the same time with only minimal loss of accuracy of 0.002 in terms of Mean Average Precision (mAP) while using the proposed scheduler. Additionally, using 4 inputs combined increases the practical FPS value from 31 to 120 and using 9 inputs increases the practical FPS value from 13 to 108, all while decreasing the mAP value by only 0.008 for 4 inputs and by only 0.034 for 9 inputs. Considering the obtained FPS values and achieved hardware efficiency, these minimal losses of mAP are easily acceptable.

Cyber attacks are carried out by unauthorized access to a system connected to an internet network anywhere in the world or by taking control of this system. These attacks continue to increase exponentially with the introduction of artificial intelligence technology, which has been used effectively in the field of science and engineering. With the use of artificial intelligence in the cyber field, conventional cyber attacks have begun to emerge as smart cyber attacks. Software development with traditional algorithms is insufficient to defend against attacks. In this study, studies in the literature on artificial intelligence methods used in the field of cyber security were examined. On the subjects discussed from different perspectives, solutions in terms of defense and attack, the applications used, the contexts between different disciplines, analyzes and examples on the basis of countries will be presented.

Nowadays, many companies use biometric technologies for the security of critical systems as well as username-password methods. In the literature, biometric systems are the most commonly used systems among the two-factor authentication systems. There are two different approaches to biometric systems: physical and behavioral biometric systems. In the last decade, the accuracy of behavioral biometric systems has significantly increased with the use of machine learning methods in these systems. For this reason, the usage areas of the studies in this field have expanded. In this study, we focus on keystroke dynamics based on behavioral methods. Firstly, we make a web application to collect keystroke data from 54 employees in a company. Then, we use the benchmark database and our database to train-test machine learning algorithms, which have the highest accuracy in this field in the literature. Among them, tree-based algorithms have the highest accuracy score, with an average of 0.94.
