Harmonious Systems Engineering Lab
Machine-translated · View original
A lab that brings artificial intelligence to society to improve people's lives.

AboutAbout the lab
AI for harmony between people and society.
The Harmonious Systems Engineering Lab aims to contribute to people's happiness and social harmony by applying artificial intelligence technology.
Its fields are broad, including deep learning, machine learning, genetic algorithms, game theory, and multi-agent systems.
The lab implements these as smartphone, cloud, and web services, and carries its research through to having people in the real world use them.
As an extension of this, venture companies have emerged from its research results, and joint research with companies is progressing.
Key terms
- Deep learning
- A machine learning method in which a neural network with many stacked layers is trained on a large number of examples so that it learns to capture features
- Multi-agent system
- A mechanism that combines multiple entities that make their own decisions and act, so that they work well as a whole
- Large language model
- Artificial intelligence that learns how words fit together from a large amount of text, enabling it to read and write sentences

*Illustrative imageTurning Clothing Designs into Reality with Image-Generating AI
The lab builds a system that gradually makes the clothing design a user has in mind more concrete through dialogue, and creates fashion images.
*Illustrative imageCaption Generation for Clothing Image Pairs
The system compares images of two similar garments and automatically generates a caption that describes the differences between them, emphasizing those differences.
*Illustrative imageA Support System for Deciding Snow Removal Dispatch
This is joint research with Horiguchi-gumi Co., Ltd. The lab is building a site for sharing road snow removal information, aiming to solve the difficulty of deciding whether to dispatch crews and the danger of patrols to check snow conditions.
*Illustrative imageImproving Text with Large Language Models
In joint research with YAMAGATA Corporation, the lab is developing a system that automatically rewrites text written by non-experts into more readable text.
