Title: On Alternative Approaches to Machine Learning

This talk explores an alternative approach to machine learning, inspired by the works of Jeff Hawkins on brain-inspired computing.
The first part introduces GraphLearner, a novel algorithm designed for learning sequences of variable length, with applications in natural language processing. Unlike traditional artificial neural networks, GraphLearner employs a continuous learning process, eliminating the need for distinct training and working phases. This allows the model to adapt dynamically to new data, mirroring how biological systems learn. The approach promises significant improvements in efficiency and adaptability for sequence-based tasks.
The second part builds on this foundation by addressing how semantic relations—such as “being smaller than”—can be derived from co-occurrence patterns in text corpora. The proposed method offers a robust framework for recovering semantic structures, providing insights that go beyond standard techniques like word embeddings. By integrating these approaches, the talk highlights a path toward more intuitive and human-like machine learning systems.

Biography: Dr. Hidekazu Yanagimoto is an Associate Professor of computer science at Graduate School of Infomatics, Osaka Metropolitan University. He received his B. A., M. A., and Doctor of Engineering from Osaka Prefecture University, Japan in 1994, 1996, and 2006 respectively. Before transitioning to academia, he worked as a researcher at Kansai C&C Research Laboratories and Human Media Research Laboratories, NEC from 1996 to 2000. During this period, he was involved in the Next-Generation Digital Library Research and Development Project. His primary focus was the development of intelligent selection methodologies for cross-searching multiple digital libraries. From 2008 to 2009, he was a Visiting Researcher at Helsinki University of Technology (now Aalto University) in Finland. 
His research interest includes natural language processing, machine learning, artificial intelligence in general, both on foudatainal and applicational topics. Sinece 2021, he has been actively involved in the SATREPS, contributing to The Project for Establishment of Risk Management of Air Pollution.

Currently, his research is centered on the innovative use of large language models (LLMs) for media conversion and the development of LLM-based services in on-premises environements. These efforts aim to bridge the gap between cutting-edge Ai technologies and real-world sicietal needs, making advanced NLP tools more accessible and impactful in diverse service domains.

Speech Title: Fine-Tuning Large Language Model for Aspect-oriented Opinion Pair Extraction with LoRA

Abstract: We propose an Aspect-oriented Opinion Pair Extraction (AOPE) system using a large language model and fine-tuning with LoRA (Low-Rank Adaptation). Large language models, such as ChatGPT, have solved various kinds of natural language tasks. For future, there is a need to customize text comprehension capabilities according to specific tasks. Existing methods using prompts often fail to achieve adequate performance when the solution process cannot be written in language. To address the issue, we fine-tune large language models using pairs of input and corresponding outputs. However, due to the vast number of tunable parameters in large language models, substantial computational costs are required for training. To overcome it, we combine the model with LoRA. To evaluate the proposed method, we conduct evaluational experiments with sentiment analysis corpus. This experiments confirmed that the proposed method achieved performance comparable to traditional methods. Specifically, for the Lapt14, Rest15, and Rest16 in SumEval corpus, we obtained F1 scores of 71.06%、71,77%, and 76.30% respectively. Additionally, the computational cost was significantly reduced compared to other methods.
