    CMC-Computers, Materials & Continua, Vol.86, No.1, pp. 1-19, 2026, DOI:10.32604/cmc.2025.069491 - 10 November 2025

    Abstract The surge in smishing attacks underscores the urgent need for robust, real-time detection systems powered by advanced deep learning models. This paper introduces PhishNet, a novel ensemble learning framework that integrates transformer-based models (RoBERTa) and large language models (LLMs) (GPT-OSS 120B, LLaMA3.3 70B, and Qwen3 32B) to enhance smishing detection performance significantly. To mitigate class imbalance, we apply synthetic data augmentation using T5 and leverage various text preprocessing techniques. Our system employs a dual-layer voting mechanism: weighted majority voting among LLMs and a final ensemble vote to classify messages as ham, spam, or smishing. Experimental More >

    Why Transformers Outperform LSTMs: A Comparative Study on Sarcasm Detection

    Palak Bari, Gurnur Bedi, Khushi Joshi, Anupama Jawale*

    Journal on Artificial Intelligence, Vol.7, pp. 499-508, 2025, DOI:10.32604/jai.2025.072531 - 17 November 2025

    Abstract This study investigates sarcasm detection in text using a dataset of 8095 sentences compiled from MUStARD and HuggingFace repositories, balanced across sarcastic and non-sarcastic classes. A sequential baseline model (LSTM) is compared with transformer-based models (RoBERTa and XLNet), integrated with attention mechanisms. Transformers were chosen for their proven ability to capture long-range contextual dependencies, whereas LSTM serves as a traditional benchmark for sequential modeling. Experimental results show that RoBERTa achieves 0.87 accuracy, XLNet 0.83, and LSTM 0.52. These findings confirm that transformer architectures significantly outperform recurrent models in sarcasm detection. Future work will incorporate multimodal More >

    Enhanced Plant Species Identification through Metadata Fusion and Vision Transformer Integration

    Hassan Javed1, Labiba Gillani Fahad1, Syed Fahad Tahir2,*, Mehdi Hassan2, Hani Alquhayz3

    CMC-Computers, Materials & Continua, Vol.85, No.2, pp. 3981-3996, 2025, DOI:10.32604/cmc.2025.064359 - 23 September 2025

    Abstract Accurate plant species classification is essential for many applications, such as biodiversity conservation, ecological research, and sustainable agricultural practices. Traditional morphological classification methods are inherently slow, labour-intensive, and prone to inaccuracies, especially when distinguishing between species exhibiting visual similarities or high intra-species variability. To address these limitations and to overcome the constraints of image-only approaches, we introduce a novel Artificial Intelligence-driven framework. This approach integrates robust Vision Transformer (ViT) models for advanced visual analysis with a multi-modal data fusion strategy, incorporating contextual metadata such as precise environmental conditions, geographic location, and phenological traits.
