All these parameters are not considered when using text. This paper presents three models created for sarcasm detection using text, audio, or a hybrid of both in Arabic, as well as deep learning and other audio-processing techniques. The results showed that using audio data mixed with text data to identify sarcasm in Arabic has promising results, with an accuracy of 0.93, a precision of 0.89, a recall of 0.92, and an F1 score of 0.91.
Accurate multivariate time series forecasting remains a fundamental challenge across critical domains including traffic management, environmental monitoring, and agricultural planning. While recent advances in deep learning have shown promise, existing approaches face inherent limitations: convolutional models struggle with long-range dependencies and cross-variable interactions, whereas pure attention-based architectures often overlook crucial local temporal patterns and suffer from quadratic computational complexity. To address these complementary weaknesses, we propose a novel hybrid architecture that systematically integrates Temporal Convolutional Networks (TCNs) for efficient local feature extraction with Transformer multi-head attention mechanisms for global dependency modeling. Our TCN-Transformer model employs dilated causal convolutions to capture hierarchical temporal patterns across multiple scales, followed by multi-head attention layers that learn cross-variable dependencies and long-range temporal relationships. We validate our approach across three diverse real-world domains: traffic volume prediction, air quality forecasting, and wheat productivity estimation across five Egyptian governorates. Experimental results demonstrate substantial improvements over established baselines, with the TCN-Transformer achieving coefficient of determination ( R^2 ) values ranging from 0.91 to 0.96 across all datasets, representing improvements of 5-13 R^2 = 0.96 . The model outperforms seven baseline approaches including statistical methods (VAR, SVR), recurrent networks (LSTM, GRU, BiLSTM), and individual deep learning components (TCN, Transformer), demonstrating robust generalization across temporal resolutions (7-day and 30-day windows), data characteristics, and application domains.

This paper presents two effective approaches for Extractive Question Answering (QA) on the Quran. It addresses challenges related to complex language, unique terminology, and deep meaning in the text. The second uses few-shot prompting with instruction-tuned large language models such as Gemini and DeepSeek. A specialized Arabic prompt framework is developed for span extraction. A strong post-processing system integrates subword alignment, overlap suppression, and semantic filtering. This improves precision and reduces hallucinations. Evaluations show that large language models with Arabic instructions outperform traditional fine-tuned models. The best configuration achieves a pAP10 score of 0.637. The results confirm that prompt-based instruction tuning is effective for low-resource, semantically rich QA tasks.
Question answering systems face critical limitations in languages with limited resources and scarce data, making the development of robust models especially challenging. The Quranic QA system holds significant importance as it facilitates a deeper understanding of the Quran, a Holy text for over a billion people worldwide. However, these systems face unique challenges, including the linguistic disparity between questions written in Modern Standard Arabic and answers found in Quranic verses written in Classical Arabic, and the small size of existing datasets, which further restricts model performance. To address these challenges, we adopt a cross-language approach by (1) Dataset Augmentation: expanding and enriching the dataset through machine translation to convert Arabic questions into English, paraphrasing questions to create linguistic diversity, and retrieving answers from an English translation of the Quran to align with multilingual training requirements; and (2) Language Model Fine-Tuning: utilizing pre-trained models such as BERT-Medium, RoBERTa-Base, DeBERTa-v3-Base, ELECTRA-Large, Flan-T5, Bloom, and Falcon to address the specific requirements of Quranic QA. Experimental results demonstrate that this cross-language approach significantly improves model performance, with RoBERTa-Base achieving the highest MAP@10 (0.34) and MRR (0.52), while DeBERTa-v3-Base excels in Recall@10 (0.50) and Precision@10 (0.24). These findings underscore the effectiveness of cross-language strategies in overcoming linguistic barriers and advancing Quranic QA systems

Ancient Egyptian hieroglyphs represent a writing system of profound historical importance, utilized for over three millennia to record religion, history, administration, and art on papyrus and stone. The task of accurately translating hieroglyphs from images remains a significant challenge, particularly with diverse layouts and orientations encountered on ancient artifacts. While prior research employed computer vision techniques for hieroglyphic recognition and translation, many approaches focused on fixed orientations and writing styles. This paper addresses these limitations by introducing a novel methodology for extracting and arranging hieroglyphic signs from real-world artifacts, irrespective of format or orientation. The proposed solution offers adaptability through two key innovations. First, Layout Analysis Stage processes complex text structures in various row and column combinations. Additionally, this study created the first Hieroglyphic Layout Analysis Dataset covering all main styles and artifact types. Second, a dynamic Sorting Function adjusts to multiple text orientations (left-to-right, right-to-left, top-to-bottom) without predetermined directionality. The "Layout Analysis, Segmentation, and Classification (LASC)" approach accurately extracts and orders hieroglyphic signs from diverse artifacts. LASC was evaluated against authentic ancient Egyptian artifacts, yielding promising results in transcribing hieroglyphic texts with complex layouts and orientations. To the best of authors' knowledge, no existing methodology exhibits this adaptability in handling hieroglyphic layout and orientation complexities.

Fuzzy Formal Concept Analysis (FFCA) is a robust mathematical tool for analyzing data, particularly where uncertainty or fuzziness is inherent. FFCA is utilized across various domains, including data mining, information retrieval, and knowledge representation. However, fuzzy concepts extraction is a crucial yet computationally intensive task. This paper addresses the challenge of time efficiency in extracting single-sided fuzzy concepts from large datasets. A parallel algorithm is proposed to reduce computational time and optimize resource utilization, thus enabling the scalable analysis of expanding datasets. By computing fuzzy concepts across multiple threads in parallel, each thread processes an attribute independently to extract fuzzy concepts, which are then merged in the final step. The proposed algorithm extracts fuzzy-crisp concepts, which are more concise than other types of fuzzy concepts. Experiments were conducted to evaluate the performance of the proposed parallel algorithm against existing sequential methods. Experimental results demonstrate significant gains in computational efficiency, with the algorithm achieving an average time reduction of 68% compared to the attribute-based algorithm and up to 83%-time reduction compared to the fuzzy CbO algorithm across various types of datasets, including binary, quantitative, and fuzzy.

The proposed system is fast and performs effective personal identification by combining both features. The features extracted from the venous print and fingerprint are matched to the nearest neighbors of the authorized person forms to verify the identity of the person. Several experiments have been performed on selected datasets to evaluate the performance of the new biometrics system. The obtained results prove that our proposed system is superior to biometric systems that use the feature of single biometrics.

Brain tumors are one of the most serious kinds of cancer that arise from the unchecked growth of brain cells inside the skull. Early and effective diagnosis of brain tumors is critical as it is a life-threatening illness. In recent decades, Deep Learning methodologies have gained significant traction for developing Computer-aided systems capable of swiftly and accurately diagnosing brain tumors. However, the primary challenge in leveraging robust deep learning models lies in identifying the most suitable classifier for a given classification task.

To address these challenges, this paper proposes several ensemble methods aimed at fusing multiple baseline deep learning models in the domain of brain tumors. To accomplish this, baseline convolution-based models are trained, including the proposed CNN model. Various ensemble techniques, such as meta-learning, voting, and weighted voting, are applied. An ensemble method is also introduced based on the fusion of extracted baseline features. Experimental results and comparative analysis on a brain tumor dataset demonstrate that ensemble methods enhance the performance of the baseline model, yielding an accuracy score improvement of 16% and 1.3%.
Hepatocellular carcinoma (HCC) stands as the pre-vailing primary liver tumor, marked by elevated mortality rates. Around 80 % of instances emerge within cirrhotic livers, presenting a considerable obstacle in determining suitable therapeutic approaches.

Results show that the Random Forest model achieves 92.77% accuracy in predicting Child-Pugh scores, while Gradient Boosting achieves 83.82 % accuracy in predicting BCLC stages. Subsequently, treatment plans are determined based on these stage and score predictions.
Brain tumors are the leading cause of death world-wide. Deep learning has been successful in previous tasks like classification. However, it's being limited by the reliance on a single imaging modality which isn't enough, where a single modality can provide higher performance but is unreliable for accurate treatment and diagnosis. This study aims to improve brain tumor classification using deep learning and fusion techniques of multiple modalities. The study employs three fusion approaches: image-level fusion, feature-level fusion, and wavelet-based fusion. Extensive experiments were conducted on the BRATS2020 dataset. Initially, we train and evaluate the performance of 21 baseline models, encompassing 20 CNN-based architectures alongside the vision transformer model. Moreover, we identify the highest-performing models within each class for fusion. Furthermore, inspired by the baseline models, we dive deeper, introducing each modality as input to its respective best-performing model and fusing the outputs for multi-modality model-level fusion. Finally, we employ wavelet-based fusion to optimize information integration, implementing Discrete Wavelet Transform on our dataset. Model-level fusion outperformed image fusion across all evaluation metrics by 1 % accuracy, 4.7% precision, 6.6 % recall, and 0.7% F1-score.

The garment sewing industry is a manufacturing sector dedicated to producing clothing and textile products. This industry encompasses a wide range of activities, including sewing and handling garments. These activities are considered value-added activities, while adjusting pieces, waiting for materials, and equipment maintenance are considered non-value-added activities. Tracking these activities is crucial for the production pipeline's efficiency. Typically, activity recognition involves the utilization of multiple deep learning models. Yet, the main obstacles in training these models revolve around identifying the most appropriate architecture and carefully fine-tuning numerous hyperparameters. This process is time-consuming and prone to errors. One potential solution to address these challenges is to incorporate ensemble learning by combining multiple, less powerful base models into a single, more robust model. Thus, this paper introduces an ensemble approach that integrates various activity recognition models through a combination of voting and meta-learning fusion techniques. Experimental results on baseline activity recognition models, including TwinsSVT, VideoMAE, and Conv3D, exhibit accuracy scores of 92%, 87%, and 70 %, respectively. Furthermore, a comparative analysis of different ensemble techniques is provided. The ensemble approach utilizing meta-learning outperforms the best baseline model, achieving an accuracy of 96% by employing extreme gradient boosting (XGBoost) as a meta-learner. This ensemble approach fuses three baseline models: TwinsSVT, VideoMAE, and Conv3D. By aggregating their predictions using various fusing methods including voting and meta-learners. The result of ensethis approach attains a 3.8 % increase in accuracy compared to solely relying on the highest performing individual model.
In the garment sewing industry, tracking worker activity is crucial for measuring production efficiency, particularly differentiating between value-added tasks (sewing, handling garments) and non-value-added activities (equipment maintenance, waiting). While traditional manual tracking methods struggle with scale and accuracy, recent efforts using deep learning, especially single-frame prediction, have aimed to address this challenge. However, these methods struggle to capture the flow of worker activity. By treating each frame independently, they miss the crucial element of time-dependent actions that define real-world work, leading to unreliable results. To overcome these limitations, this paper proposes an approach that considers both spatial (worker pose in a frame) and temporal information (sequence of worker actions) for robust worker activity recognition. The study compares the accuracy of different approaches in classifying tasks as value-added or non-value-added. This includes evaluating keypoint extraction methods (MoveNet, MediaPipe with LSTMs) against video classification using whole frames with convolutional neural networks (CNNs) including 3D convolutional layers (Conv3D), and video transformers (VideoMAE). Resulting in a 30% increase in accuracy when compared to keypoint extraction method.
