abstract = {This study focuses on detecting spam emails, a key vector for cyberattacks. It introduces 56 features based on NLP techniques, grouped into five categories: Headers, Text, Attachments, URLs, and Protocols. A new dataset, SERC, was created for spam risk classification. Using binary classification and regression, the Random Forest classifier achieved the best performance (F1-Score of 0.914), and Random Forest Regressor had the lowest Mean Square Error (0.781). Features from the Headers and Text groups were found to be the most important.},

abstract = {This paper explores the use of supervised machine learning models to detect persuasion techniques in spam emails, addressing both binary classification (presence/absence of persuasion) and multilabel classification (identifying specific persuasion techniques). The research utilizes natural language processing and adapts propaganda detection methods from news articles, analyzing emails at full-text, sentence, and snippet levels. The study includes the development of a custom spam dataset and fine-tuning of RoBERTa-based models, ultimately aiming to enhance cybersecurity through better understanding of persuasion tactics in malicious emails.},

The push kernel learns to respond to specific stimuli, while the pull kernel reacts to opposite contrasts. This design enhances stimulus selectivity and improves robustness by inhibiting responses in regions without preferred stimuli. Integrating PushPull-Conv into ResNets improves their resilience to image corruption.},

The datasets are classified into eleven categories. The best results for English (F1-score: 0.953, 94.6% accuracy) were achieved with TF-IDF and Logistic Regression, while for Spanish, TF-IDF and Naïve Bayes achieved an F1-score of 0.945 and 98.5% accuracy. TF-IDF with Logistic Regression also had the fastest processing time (2ms per email for English and 2.2ms for Spanish).},

La sostenibilidad de los proyectos de ingeniería es clave para alcanzar el objetivo 55 de la Unión Europea, que busca reducir las emisiones de CO2 en un 55% para 2030. En este contexto, debido a la falta de alternativas reales a los materiales basados en cemento, es crucial desarrollar estrategias para descarbonizar los proyectos. Los materiales de cemento son responsables de un 30% de las emisiones globales de CO2 durante la vida útil de las infraestructuras, por lo que la búsqueda de cementos con menor huella de carbono podría aumentar la sostenibilidad de los proyectos. Este estudio evalúa la reducción de emisiones de CO2 en un proyecto que utiliza cementos convencionales en comparación con aquellos que incorporan nuevos cementos de bajo carbono.},

The authors present a new dataset, SEA-Faces-30k, consisting of 30,000 manually labeled images categorized as erotic, suggestive-erotic, or non-erotic. Given the difficulty of obtaining large annotated datasets for training deep learning models, they propose a semi-supervised GAN framework, Triple-BigGAN, which learns both a generative model and a classifier simultaneously using unlabeled or partially labeled data. The Triple-BigGAN framework achieves strong performance on the SFER task and performs well on several benchmark datasets. The study also demonstrates that synthetic erotic face images generated by Triple-BigGAN can enhance the performance of deep learning classifiers.},

abstract = {Grass silage is commonly used as a forage source in winter for finishing bull in European regions under oceanic climates, such as the Cantabrian cornice, where the local Tudanca breed is produced. Grass silage, compared with barley straw in the bull’s diet showed an effect on beef quality, i.e., increased saturated fatty acids, n-3 fatty acids, and β-carotene and decreased monounsaturated and polyunsaturated fatty acids. Beef from silage-fed bulls and straw-fed bulls could be differentiated by fatty acid percentages, especially 18:0, t-18:1, and c9-18:1, b-carotene content, b* colour value, and carotenoid colour index.},

Images of parts produced by traditional sand molding and the Binder Jetting (BJ) additive technique are analyzed. The method uses SIFT descriptors and BoVW features to train two SVM classifiers: one for detecting pores and another for classifying the type of porosity (gas-related or shrinkage-related). This automated approach improves inspection efficiency and accuracy compared to traditional manual methods.},

The proposed methodology transfers the knowledge gained by CNNs to classical machine learning algorithms. The study shows that Grad-CAM highlights key regions of spectrograms important for accent prediction, and the generated Grad-Transfer descriptors effectively distinguish different accents. Experiments on the Voice Cloning Toolkit dataset demonstrate an improvement in accent classification accuracy and recall when using Grad-Transfer, outperforming models trained directly on spectrograms.},

abstract = {Leveraging image-based age estimation in preventing Child Sexual Exploitation Material (CSEM) content over the internet is not investigated thoroughly in the research community. While deep learning methods are considered state-of-the-art for general age estimation, they perform poorly in predicting the age group of minors and older adults due to the few examples of these age groups in the existing datasets. In this work, we present a data augmentation strategy to improve the performance of age estimators trained on imbalanced data based on synthetic image generation and artificial facial occlusion. Facial occlusion is focused on modelling as CSEM criminals tend to cover certain parts of the victim, such as the eyes, to hide their identity. The proposed strategy is evaluated using the Soft Stagewise Regression Network (SSR-Net), a compact size age estimator and three publicly available datasets composed mainly of non-occluded images. Therefore, we create the Synthetic Augmented with Occluded Faces (SAOF-15K) dataset to assess the performance of eye and mouthoccluded images. Results show that our strategy improves the performance of the evaluated age estimator.},

Despite high-performing spam filters based on machine learning, users continue to report rising incidents of fraud and attacks via spam. This paper highlights two key challenges in spam email detection: the dynamic nature of the environment, leading to dataset shift, and the presence of adversarial actors (spammers). The review focuses on the impact of these challenges and examines various spammer strategies and state-of-the-art techniques for developing robust filters. Experimental results show that ignoring dataset shift can severely degrade the performance of spam filters, leading to high error rates.},

Task 1 involves detecting propaganda (binary classification), while Task 2 and Task 3 categorize the type of propaganda into four groups and 15 techniques (multi-label classification). We propose a pipeline using four multi-label models to identify propaganda techniques, followed by group identification and binary classification. Our submission based on RoBERTa for the English tasks achieved top positions, with scores of 0.1835 for Task 1 (3rd place), 0.1342 for Task 2 (2nd place), and 0.0693 for Task 3 (5th place). For the Spanish tasks, using BERTIN, we achieved 0.6301 for Task 1 (4th place), -0.0134 for Task 2 (1st place), and -0.1478 for Task 3 (1st place).},
