Regular exercise is a crucial aspect of daily life, as it enables individuals to stay physically active, lowers thelikelihood of developing illnesses, and enhances life expectancy. The recognition of workout actions in videostreams holds significant importance in computer vision research, as it aims to enhance exercise adherence, enableinstant recognition, advance fitness tracking technologies, and optimize fitness routines. However, existing actiondatasets often lack diversity and specificity for workout actions, hindering the development of accurate recognitionmodels. To address this gap, the Workout Action Video dataset (WAVd) has been introduced as a significantcontribution. WAVd comprises a diverse collection of labeled workout action videos, meticulously curated toencompass various exercises performed by numerous individuals in different settings. This research proposes aninnovative framework based on the Attention driven Residual Deep Convolutional-Gated Recurrent Unit (ResDCGRU)network for workout action recognition in video streams. Unlike image-based action recognition, videoscontain spatio-temporal information, making the task more complex and challenging. While substantial progresshas been made in this area, challenges persist in detecting subtle and complex actions, handling occlusions,and managing the computational demands of deep learning approaches. The proposed ResDC-GRU Attentionmodel demonstrated exceptional classification performance with 95.81% accuracy in classifying workout actionvideos and also outperformed various state-of-the-art models. The method also yielded 81.6%, 97.2%, 95.6%, and93.2% accuracy on established benchmark datasets, namely HMDB51, Youtube Actions, UCF50, and UCF101,respectively, showcasing its superiority and robustness in action recognition. The findings suggest practicalimplications in real-world scenarios where precise video action recognition is paramount, addressing the persistingchallenges in the field. TheWAVd datas

For text mining applications, keyword extraction is a popular problem to solve. The text mining applications as indexing, summarization and topic tracking uses keyword extraction models as baseline. There are many sequence labeling models proposed in the literature. The performance results, however, did not meet expectations. In this paper, we use many selective statistical and graph-based features to solve the keyword extraction problem. We calculated many selective features for each considerable word in input text. We used Random Forest token classification model. In addition to widely used 500N-KPCrowd dataset in the literature, we trained and tested publicly available KazakhNews and RussianNews datasets to extend language domain. Moreover, we collected two news dataset in Chinese and Arabic languages namely ChineseNews and ArabianNews. We also used a Turkish abstract dataset DergiParkTR for comparison. The performance of the graph-based and statistical features were tested with Random forest algorithm. We have obtained 0.680, 0.706 and 0.896 Fl-scores for DergiParkTR, 500N-KPCrowd and RussianNews datasets respectively. We attained the best performance of 0.978 for KazakhNews using graph-based features and 0.999 for ChineseNews datasets with all statistical features. © 2024 IEEE.

Skin cancer constitutes a third of all cancer diagnoses worldwide, with its incidence steadily increasing over recent decades. The introduction of dermoscopy has significantly improved the diagnostic accuracy for skin cancer. However, dermatologists face considerable challenges in accurately diagnosing skin cancer due to the similar appearances of different types. The diagnostic accuracy among dermatologist’s ranges between 62 and 80%. The research community has achieved significant progress in creating automated systems to aid dermatologists in decision-making. This work presents a very precise automated computer-aided diagnostic (CAD) system for multi-class skin cancer classification. Our suggested strategy improves the accuracy of both skilled dermatologist and existing deep learning techniques in MCS cancer classification. Utilizing the HAM10000 dataset, we fine-tuned models across seven skin cancer classes and conducted a comparative study to evaluate the performance of three pre-trained convolutional neural networks (CNNs) and three ensemble models. Our results demonstrated a maximum accuracy of 92.16% for the best-performing individual model and an impressive 94.17% accuracy for the ensemble model. We suggest for taking advantage of InceptionV3, which for MCS cancer classification owing to its improved architecture and enhanced accuracy. This research underscores the capability of sophisticated deep learning models to improve the diagnostic process for skin cancer, providing a significant resource to assist dermatologists in attaining more precise diagnoses. © The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd. 2025.

An ultra-wideband (UWB) slotted compact Vivaldi antenna with a microstrip line feed was evaluated for microwave imaging (MI) applications. The recommended FR4 substrate-based Vivaldi antenna is 50×50×1.5 mm3 in size. The proposed compact Vivaldi antenna showed good radiation characteristics and spanned an ultra-wide bandwidth of 10 GHz, ranging from 3.6 to 13.6 GHz, using a microstrip line feed with a radial stub, tapered slots, and resonant cavities. After analyzing the simulation findings, the proposed compact slotted UWB Vivaldi antenna was compared with the basic Vivaldi antenna. The maximum gain and efficiency were 7.35 dB and 82%, respectively. The antenna was simulated in the time domain using the computer simulation technology (CST) microwave studio. The frequency domain solver was also used for cross-validation, and the results were equally good. In conclusion, the proposed compact Vivaldi antenna is a good option for microwave imaging applications. © 2023 The Institute of Electronics and Information Engineers.

Unstructured Numerical Image Dataset Separation (UNIDS) method employing an enhanced unsupervised clustering technique. The objective is to delineate an optimal number of distinct groups within the input grayscale (G-S) image content, utilizing the improved limited iteration agglomerative clustering (iLIAC) clustering technique for the separation and enhancement of picture elements. The UNIDS method is structured into two primary stages: partitioning and validation. In the partitioning stage, the UNIDS method identifies an appropriate number of discrete clusters within the grayscale image using the iLIAC technique, eliminating the need for predetermined procedures. Subsequently, the method evaluates the similarity and deviation among data elements within the same group in the resultant image dataset. Additionally, it assesses the proximity and inters severance among clusters in the outcome of the image dataset through the partitioning process. Empirical results indicate that the UNIDS system excels in the spontaneous identification of an optimal number of discrete clusters within the input G-S image. The system demonstrates superior thickness, reduced deviation among data elements within the same cluster, increased inter-separation, and diminished inter-closeness between cluster elements. Furthermore, empirical analysis establishes the superior performance of the UNIDS approach compared to existing clustering techniques. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.
