Makoto Onizuka, Professor
0 student voices
The Big Data Engineering Lab researches cutting-edge component technologies in areas such as big data, natural language processing, data mining, and artificial intelligence. Its research themes are wide-ranging, including graph deep learning, graph databases, and large language models. The lab also aims to create new value by applying its technologies to big data held by companies. On the lab's website, it is introduced under the name “Onizuka Lab.”

Akihiro Maruta, Professor
0 student voices
The Photonic Network Engineering Lab (Maruta Lab) researches information and communication technologies based on waves such as lightwaves, radio waves, and sound waves, starting with optical fiber communication technology. The lab aims to realize next-generation optical networks that can transmit and forward ever-growing Internet traffic faster and more efficiently. From theoretical analysis through numerical simulation to experiments, the lab proceeds under the motto “Let’s just try it!” Each student is generally given an individual research topic, and once results begin to emerge, they present at domestic and international conferences.

Takahiro Hara, Professor
0 student voices
Hara Lab conducts research on building advanced multimedia information systems by integrating various component technologies with database technology, the core of information technology. The technologies combined include multimedia information processing, computer networks, and virtual reality. Many of the themes explore the potential for creating new businesses, and are carried out as joint projects with various companies and other organizations. The lab actively creates opportunities to present its research results at academic conferences in Japan and abroad.

Yuichi Tanaka, Professor

Tanaka Lab studies techniques for analyzing a wide variety of data, with signal information processing as its foundation. Its targets include sensor network data such as that from IoT, multimedia data such as point clouds and video, and biological data such as EEG and neural networks. On the lab's website, it is introduced under the name "Tanaka Lab."

Tetsuya Takine, Professor
0 student voices
The Robust Network Engineering Lab (Takine Lab) aims to establish control and design methods for flexible, robust communication networks that can smoothly accommodate a wide variety of network applications. Based on communication traffic theory, the lab conducts research for network control and design, including traffic modeling, performance evaluation of various types of traffic, and congestion control. It belongs to the Information and Communications Engineering Division of the Department of Electrical, Electronic and Infocommunications Engineering, Graduate School of Engineering, Osaka University. The lab's history dates back to the Fifth Chair of Communication Engineering, established in 1969.

Hideki Ochiai, Professor

The Wireless Systems Engineering Lab studies technologies for processing wireless communication signals, such as massive MIMO, which uses a large number of antennas. To separate the information of many users simultaneously at a receiver, conventional signal processing has the problem that the amount of computation becomes too large. Focusing on the fact that high performance can be achieved while reducing the amount of processing when the number of dimensions is very large, the lab studies methods based on insights from statistical mechanics. On the lab's website, the lab is presented under the name "Ochiai Lab."

Taro Maeda, Professor

The Human Information Engineering Lab (Maeda Lab) studies the mechanisms of human sensation and movement and develops systems that make use of them. Humans obtain information through senses such as vision and hearing, and act on the outside world through movement using their muscles. The relationship between sensation and movement can be analyzed quantitatively as the input and output of information. The lab explains that, unlike hallucinations, illusions are a normal brain function that occurs in anyone, and that using them makes it possible to guide behavior naturally. The lab also works on the transmission and sharing of sensations, which allows a person to experience what a distant person is seeing or touching.

Susumu Date, Professor

The Advanced High-Performance Computing Infrastructure Systems Lab conducts research and development on computing infrastructure centered on supercomputing. The lab is located at the D3 Center of The University of Osaka and draws on its experience in building and operating supercomputing systems, large-scale visualization systems, and data infrastructure. The lab considers how to perform large-scale computation such as AI development and numerical simulation with high performance and efficiency, and how to bring out the performance of the computing infrastructure from applications. On the lab's website, the lab is also presented under the name "Date Lab."

Takuya Maekawa, Professor
0 student voices
The Real-World Intelligence Foundation Lab researches artificial intelligence that estimates the behavior of humans and animals from sensor data. Spanning fields such as IoT, wearables, and biologging, the lab designs sensors, data, algorithms, and implementation as one integrated whole, aiming to establish an intelligence foundation that works in real environments. The research proceeds in four areas: human activity recognition, AI biologging, indoor positioning, and real-world data mining. The lab's website also introduces it under the name "Maekawa Lab."

Takao Onoye, Professor
0 student voices
The Information Systems Architecture Lab (Onoye Lab) researches the architecture design of computer systems in cyber-physical systems, toward a new society that integrates cyberspace and physical space. In addition to research on design methodologies for the underlying hardware and software, the lab covers a wide range of work, including prototyping and demonstration experiments for social implementation. Working with companies and research institutions in Japan and abroad, the lab targets a wide range of research areas, including energy management systems, intelligent transport systems, in-vehicle systems, and medical image analysis.
