The lab uses algorithm theory to handle large-scale data at extremely high speed.

AboutAbout the lab
In search of the “Art” that bridges Science and Engineering.
The Large-Scale Knowledge Processing Lab studies foundational technologies for handling large-scale data at extremely high speed, based on cutting-edge algorithm theory.
At the base of information science lies mathematical theory, and above it lie practical techniques for solving individual problems. The lab's goal is to build a general-purpose technological foundation that connects these two layers.
For this reason, the lab values not only conceptual and theoretical results but also implementing algorithms that hold up in practical use.
While pursuing fundamental principles, the lab also sharpens its members' craft as engineers, aiming to solve real-world problems with solid grounding.
Key terms
- Algorithm
- A computational procedure or strategy for solving a problem. With clever design, computation time can be cut by tens of times
- Combinatorial optimization
- The problem of choosing the best option that satisfies given conditions from among a large number of combinations
- Enumeration algorithm
- A computational procedure that counts or lists all items satisfying given conditions, without duplicates and without omissions

*Illustrative imageFoundational technologies for large-scale data
In an age when big data circulates widely, the lab builds foundational technologies that handle large-scale data at extremely high speed, so that searching, editing, classifying, analyzing, enumerating, and indexing the knowledge people need can be done smoothly.
*Illustrative imageThe “Art” that connects theory and implementation
Cross-disciplinary mathematical theory on one side, and practical techniques specialized for individual problems on the other. Aiming to build a general-purpose technological foundation that bridges the two, the lab implements algorithms that emphasize simplicity and generality.
*Illustrative imageAlgorithm theory and computational complexity
The lab studies exact algorithms, the satisfiability problem, circuit complexity, and related topics. The focus is on algorithm design and on theoretical analysis of the computation time and memory needed to find a solution.
*Illustrative imageApplications to social infrastructure systems
Drawing on machine learning, artificial intelligence, data mining, statistical science, system optimization, and information security, the lab aims to contribute to the analysis and design of social infrastructure systems such as power, communications, transportation, commerce, and disaster prevention.
