Title:Modern Data Mining on Big Data and Digital Management: A 2025 Perspective

Abstract: As digital transformation accelerates in 2025, data mining techniques have evolved to meet the increasing complexities of big data and digital management. This talk will focus on how Large Language Models (LLMs), Small Language Models (SLMs), and Generative AI (GenAI) can be applied in a real-world scenario, particularly for small and medium-sized enterprises (SMEs). AI and ML continue to revolutionize automation in pattern detection, predictive analytics, and decision intelligence. The integration of cloud and edge computing has enabled real-time data processing, reducing operational costs and enhancing efficiency. Industries such as finance, healthcare, and property development leverage these technologies to drive informed decision-making. However, challenges persist, including governance, compliance, ethical AI, bias mitigation, scalability, and interoperability. Standardized data exchange protocols are essential to streamline integration and maintain regulatory compliance. AI-powered decision intelligence systems are transforming strategic planning and operations. Despite increasing automation, human expertise remains crucial in interpreting complex data patterns, necessitating human-centric AI approaches. This paper explores the latest trends, challenges, and opportunities in data mining and digital management, demonstrating how emerging technologies can be leveraged for innovation and competitive advantage in the evolving digital landscape.










Prof. Jianhua Zhang, Oslo Metropolitan University, Norway


Biography: Prof. Jianhua Zhang has been Professor in Computer Science at Oslo Metropolitan University (OsloMet), Norway since 2018. Before joining OsloMet, he spent a stint working at a French IT company, Vekia (Lille, France) as Scientific Director. He was Professor at East China University of Science and Technology (Shanghai, China) between 2007 and 2017. He received PhD from Ruhr University Bochum, Germany and did postdoc. at The University of Sheffield, UK. He was Guest Scientist at Dresden University of Technology, Germany from 2002 to 2003 and Visiting Professor at Technical University of Berlin, Germany during 2008-2015. His research interests include computational intelligence, machine learning and pattern recognition, data modeling and analytics, intelligent systems and control, modeling and control of complex systems, biomedical signal processing and data analysis, and neurocomputing (in particular, neuroergonomics and affective computing). He serves as Chair of IFAC (International Federation of Automatic Control) Technical Committee on Human-Machine Systems for two consecutive terms (2017-2023), Vice Chair of IEEE Norway Section, and Vice Chair of IEEE CIS Norway Chapter. He is on editorial board of 4 international scientific journals, including Frontiers in Neuroscience, Cognitive Neurodynamics, and Cognition, Technology and Work. He was chair or keynote speaker for a number of international scientific conferences.


Title:Stock Market Forecasting via Transformer Models

Abstract: This talk examines the effectiveness of various models, such as traditional models like ARIMA and Linear Regression and advanced machine learning (ML) models like Long Short-Term Memory (LSTM) networks, Prophet, and Transformers, in predicting stock prices. Ensemble learning, which combine predictions of different models to reduce their bias and variance, are also examined. Furthermore, optimizing ML models for stock price prediction requires hyperparameter tuning to ensure that models are effective and efficient in capturing the complexities and volatility of real-world financial markets. To maximize accuracy while minimizing computational costs, different hyperparameter (such as learning rate, number of layers in the network, and batch size) tuning strategies are investigated, including grid search, random search, and Bayesian optimization.
The extensive real stock data analysis experiments showed that the transformer model stacked with linear regression achieves superior prediction performance. We found that it is important to adapt model architectures to specific stock market characteristics and that ensemble learning methods can improve the accuracy and reliability of stock time series forecasting. The findings of this study may provide useful insight into the proper selection of model class for stock closing price dynamics as well as informed stock investment decisions and portfolio management.

Title:Information Retrieval: Evolving from Pre-trained to Large Languages Models

Abstract: Since the introduction of the Transformer architecture, pre-trained language models have demonstrated significant efficacy across various tasks in natural language processing. In the domain of information retrieval (IR), particularly concerning text relevance ranking, numerous models have been proposed, continually updating the algorithms used in everyday search engines. This report will introduce a variety of algorithms based on pre-trained language models, including interaction-based, representation-based approaches and others. Furthermore, given the recent emergence of large language models (LLMs) in the field of artificial intelligence, the report will also cover IR algorithms based on LLMs, as well as the role of IR in augmenting dialogue and question-answering capabilities of LLMs.
