Item type:Publication, Air Pollution Forecasting Using CNN-LSTM Deep Learning Model(IEEE, 2021-09-27) ;Jovova, LencheOne of the greatest issues modern urban environments are facing is poor air quality. It directly affects human health having a long-term negative impact on people's lives and is a major cause of deaths in the world. Smart cities combined with advances in deep learning provide a novel platform for dealing with this problem. This paper uses pollution data from smart sensor networks and a CNN-LSTM architecture to forecast the air pollution concentration of the current hour based on the previous 24-hour pollution concentration and several meteorological features from the previous hour. Initially data is preprocessed with special focus and strategy for handling missing values. The performance of the model is fine-tuned by taking into account additional temporal and seasonal dependency of this type of data. Comparison with other models from classical machine learning shows that the proposed deep learning model has better performance according to the provided metrics. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Bridging Gaps in Ligand Binding Affinity Prediction: Empirical Machine Learning Analyses(IEEE, 2025-06-02) ;Fetaji, Fjolla; Predicting ligand binding affinity remains a critical challenge in computational drug discovery, as existing techniques often require extensive computational resources and are not readily generalizable to diverse protein-ligand systems. This study addresses three key gaps in current research: (1) the lack of versatile, data-efficient predictive models; (2) insufficient strategies for integrating protein and ligand structural information; and (3) limited methods for simultaneously improving accuracy and generalizability. By systematically reviewing recent advances in machine learning-including approaches derived from deep learning, graph-based methodologies, and hybrid frameworks-we show how emerging techniques enable higher predictive power and reduced computational cost. We leverage two large-scale, public datasets (PDBBind and BindingDB) to empirically evaluate a novel dual-model framework that integrates graph-based feature extraction and neural network regression. Comparative analyses illustrate how spatial and sequence representations contribute to model performance, achieving robust improvements in binding affinity prediction. The theory-based advantages of this approach demonstrate how it reveals both small-scale and wide-ranging relationships between proteins and their ligands and the operational benefits result in quicker medication development through decreased processing needs. The research confirms the necessity of building adaptable frameworks which unite structural data with sequence data for therapeutic advancement along clear research paths. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Hate Speech on Social Platforms through the Application of ML and NLP Methods(IEEE, 2024-05-20) ;Paunkoska, SaraHateful behavior on social platforms has recently become a topic of interest for many researchers. Users experience online encounters with instances of hate speech on a daily basis. This paper investigates how using modern machine learning and natural language processing techniques and methods make computer systems enhance their intelligence to effectively recognize words indicative of hate speech or insults. A performance comparison is conducted using an extensive dataset of publicly available posts, evaluating traditional classifiers against classifiers that rely on deep learning. The results indicate that the overall success of the model is not solely determined by the choice of classifier, but also by factors such as pre-processing of textual data and the accurate configuration of parameters. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, COVID-19 Fake News Detection by Using BERT and RoBERTa models(IEEE, 2022-05-23) ;Pavlov, TashkoWe live in a world where COVID-19 news is an everyday occurrence with which we interact. We are receiving that information, either consciously or unconsciously, without fact-checking it. In this regard, it has become an enormous challenge to keep only true COVID-19 news relevant. People are exposed to these stories on a daily basis, and not all of them are true and fact-checked reports on the COVID-19 pandemic, which was the primary reason for our research. We accepted the challenge that fake news is extremely common and that some people take these news as they are. Knowing the true power of the most recent NLP achievements, in this research we focus on detecting fake news regarding COVID-19. Our approach includes using pre-trained BERT and RoBERTa models, which we then fine-tune on real and fake news about the COVID-19 pandemic. By using pre-trained BERT and RoBERTa models on tweet data, we explore their capabilities and compare them to previous research in regard to fine-tuned BERT models for this task in which we achieve better accuracy, recall and f1 score. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Classification of Protein Structures Using Deep Learning Models(IEEE, 2022-05-23); ; Protein molecules are very important in the organisms because they participate in different processes. Understanding the way they interact in the cells is of high importance. In order to understand that, solving the task of protein classification could be really helpful thus providing valuable knowledge about the similar proteins that belong to same class. In this paper we focus on solving the task of protein classification. First, we extract some features of the proteins thus obtaining feature vectors, and then by using deep learning architecture, we create prediction model that could be used for classifying protein structures. We present some experimental results of the obtained classification models. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Few-Shot Semantic Segmentation in Remote Sensing: A Review on Definitions, Methods, Datasets, Advances and Future Trends(MDPI AG, 2026-02-18) ;Petrov, Marko ;Pandilova, Ema; ; Semantic segmentation in remote sensing images, which is the task of classifying each pixel of the image in a specific category, is widely used in areas such as disaster management, environmental monitoring, precision agriculture, and many others. However, traditional semantic segmentation methods face a major challenge: they require large amounts of annotated data to train effectively. To tackle this challenge, few-shot semantic segmentation has been introduced, where the models can learn and adapt quickly to new classes from just a few annotated samples. This paper presents a comprehensive review of recent advances in few-shot semantic segmentation (FSSS) for remote sensing, covering datasets, methods, and emerging research directions. We first outline the fundamental principles of few-shot learning and summarize commonly used remote-sensing benchmarks, emphasizing their scale, geographic diversity, and relevance to episodic evaluation. Next, we categorize FSSS methods into major families (meta-learning, conditioning-based, and foundation-assisted approaches) and analyze how architectural choices, pretraining strategies, and inference protocols influence performance. The discussion highlights empirical trends across datasets, the behavior of different conditioning mechanisms, the impact of self-supervised and multimodal pretraining, and the role of reproducibility and evaluation design. Finally, we identify key challenges and future trends, including benchmark standardization, integration with foundation and multimodal models, efficiency at scale, and uncertainty-aware adaptation. Collectively, they signal a shift toward unified, adaptive models capable of segmenting novel classes across sensors, regions, and temporal domains with minimal supervision. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Processing MIMIC-III for Evaluation of Various Blood Pressure Estimation Models(2024); ;Kuzmanov, Ivan; ;Lehocki, FedorMadevska Bogdanova, AnaThe development of non-invasive easily available blood pres- sure estimation methods using electrocardiogram - ECG and/or photo- plethysmogram - PPG signals has gained increasing attention. However, there is a lack of consistency in the evaluation of these methods due to variations in the size and availability of data in published datasets. Our research involves retrieving, cleaning, and storing a portion of the MIMIC-III database for utilization in model training and testing. This paper outlines our methodology for processing the MIMIC-III database, along with the challenges encountered during the process.
