The lighting conditions at the environment are not favorable for imaging, and the problem of light is one of the challenges of imaging in the environment. The lack of sufficient light in the images reduces the quality and details of recognition by humans. In this paper, a hybrid method for image enhancement in low light is proposed. At first, dark/bright channel algorithm based on low-light images is used for minimum/maximum brightness images. In the next step, the fuzzy algorithm is used to weight different levels of brightness, and finally, the brightness mapping estimation method called LIME is used along with a denoising to improve the image. To evaluate the proposed method, the Universal Image Quality Index (UQI) indices were used, and the results obtained on the base images proved the performs of the method we proposed is better than the other novel methods. © 2022 IEEE.

Teaching students complex problem-solving skills using large-scale, real-world problems is challenging for both students and teachers alike. As a result, most courses use small, well-specified, toy-like problems, which are not representative of what students will encounter in the workforce. One approach that allows teachers to use large-scale problems in class is by introducing scaffolding. Scaffolding breaks a larger problem into smaller steps, which students can solve independently, while deemphasizing tangential concepts such as the complex configuration files needed to compile open-source software systems. Strong scaffolding supports student learning, preventing them from getting bogged down with unnecessary tasks or overwhelmed by complexity. This work investigates a scaffolded problem-based-learning module for computing courses, using a realistically-sized project with characteristics representative of the industry. The project was implemented in a computer science course with roughly 100 students, and the results speak to the importance of scaffolding for student success. In fact, there were two student assignments that lacked sufficient scaffolding, compared with other tasks, and the reduction in student scoring and persistence shows that project scaffolding is necessary when implementing these types of assignments. Most students felt the project helped prepare them for a job in their chosen field. © 2023 IEEE.

Unmanned aerial vehicles (UAVs) rely on optical sensors such as cameras and lidar for autonomous operation. However, such optical sensors are error-prone in bad lighting, inclement weather conditions including fog and smoke, and around textureless or transparent surfaces. In this paper, we ask: is it possible to fly UAVs without relying on optical sensors, i.e., can UAVs fly without seeing? We present BatMobility, a lightweight mmWave radar-only perception system for UAVs that eliminates the need for optical sensors. BatMobility enables two core functionalities for UAVs - radio flow estimation (a novel FMCW radar-based alternative for optical flow based on surface-parallel doppler shift) and radar-based collision avoidance. We build BatMobility using commodity sensors and deploy it as a real-time system on a small off-the-shelf quadcopter running an unmodified flight controller. Our evaluation1 shows that BatMobility achieves comparable or better performance than commercial-grade optical sensors across a wide range of scenarios. © 2023 ACM.

Breast cancer is a leading cause of cancer-related deaths globally, necessitating effective diagnostic measures. Tissue biopsy examination and histopathology image analysis are pivotal in clinical cancer diagnosis. Various feature extraction approaches and classifiers have been introduced for histopathology analysis by the research community. This study focuses on enhancing tissue classification systems through two distinct pipelines applied to the Databiox dataset. In the first pipeline, histopathological images undergo segmentation using the watershed algorithm. Subsequently, features are extracted from the segmented images using the gray level co-occurrence matrix and VGG16 model. The extracted features are then classified using two classifiers, namely dense layer of CNN and Random Forest. The second pipeline involves extracting features directly from entire histopathological images, with subsequent classification using gray level co-occurrence matrix and VGG16 model. Dense layer and RF classifiers are employed to classify the features from whole images. Additionally, Principal Component Analysis is employed to select crucial feature vectors. The evaluation of direct and segmented histopathological images from the Databiox dataset, with a focus on segmentation, reveals a gap in existing literature. Experimental results demonstrate that the VGG16 model, coupled with a classifier, yields superior outcomes when applied to entire histopathological images compared to segmented images. © 2024 IEEE.

To enable large-scale and efficient deployment of artificial intelligence (AI), the combination of AI and edge computing has spawned Edge Intelligence, which leverages the computing and communication capabilities of end devices and edge servers to process data closer to where it is generated. A key technology for edge intelligence is the privacy-protecting machine learning paradigm known as Federated Learning (FL), which enables data owners to train models without having to transfer raw data to third-party servers. However, FL networks are expected to involve thousands of heterogeneous distributed devices. As a result, communication efficiency remains a key bottleneck. To reduce node failures and device exits, a Hierarchical Federated Learning (HFL) framework is proposed, where a designated cluster leader supports the data owner through intermediate model aggregation. Therefore, based on the improvement of edge server resource utilization, this paper can effectively make up for the limitation of cache capacity. In order to mitigate the impact of soft clicks on the quality of user experience (QoE), the authors model the user QoE as a comprehensive system cost. To solve the formulaic problem, the authors propose a decentralized caching algorithm with federated deep reinforcement learning (DRL) and federated learning (FL), where multiple agents learn and make decisions independently. © 2024 SPIE.

In some real-world data sets, there is a class imbalance where one class (the minority class) has a limited number of data points and the other class (the dominant class) has a large number of data points. With the state-of-the-art machine learning approaches, it is extremely challenging to build an efficient model without taking data preparation into account to balance the unbalanced data sets. To ensure that each class has the same number of data points, random under-sampling has been used in numerous research. During the data preparation phase of this study, this research experiments with under-sampling techniques that use a clustering technique. This Research uses under-sampling techniques with normalization in this non-interest-bearing imbalanced data collection with a majority and minority class. Both majority and minority classifications contain personal information focuses. This Research first uses k-fold cross-validation to separate this unbalanced data set into preparation and testing sets. This Research separates the data into a majority course subset and a minority course subset after normalizing it. The majority of lesson information evaluations are minimized by using a clustering-based under-sampling method. The minority lesson subset is then combined with the reduced lion's share course subset to create an updated preparation set. Then The author normalizes the information once more at that moment. The classifier is then independently prepared and evaluated using the updated preparation and testing sets. © 2022 IEEE.

A key facilitating infrastructure for building intelligent structures that enable efficient in-person and virtual learning environments is the Internet of Things (IoT). The shift to smart learning, that includes IoT and Artificial Intelligence (AI) into the educational system, is enticing since it directly affects the motivation of learners, enrolment, participation, and in-depth understanding. Teaching and learning, management, examination, and class monitoring are only a few of the numerous issues that afflict conventional education. Many ingenious approaches to many facets of our lives are being made possible by modern advancements in information and communication technology (ICT);nonetheless, these imaginative concepts aren't adequately incorporated into the framework of education. The COVID-19 pandemic scenario, in specific, has brought out the need for innovative, creative approaches in the field of teaching. The present research examines previous investigations in the field and discusses the following topics: (i) issues with the current educational system and potential fixes;(ii) the shift to smart learning;and (iii) scientific hurdles (such as technological and cultural barriers) in making the move to smart learning. In accordance with these outcomes, creative approaches to the issues with the conventional system-such as smart teaching, smart evaluation, smart school environment, and smart management-are presented. The business and academic community may now include IoT, AI, and ICT into smart learning owing to the aforementioned experimental research's novel developments. © 2024 IEEE.
