The lab develops machine learning methods for understanding the big picture of large-scale data.

AboutAbout the lab
Turning data into understandable knowledge
Matsushima Lab studies the foundations of machine learning for understanding data.
Data of many kinds is generated in society every day, including urban infrastructure, healthcare and health, marketing, and materials.
The lab studies techniques that express the analysis results obtained from such large-scale data as knowledge in order to understand the big picture of complex data, along with the optimization algorithms needed for them.
Students can work on both the fundamental theory of machine learning and its practical applications.
Key terms
- Optimization algorithm
- A computational procedure for efficiently finding, among many candidates, the value that best fits the objective
- Interpretable predictive model
- A prediction mechanism whose results come with an explanation, understandable to people, of why that prediction was made
- Causal discovery
- Estimating from data which factors are the causes of which other factors, that is, the causal connections among them

ResearchResearch themes
The lab studies the foundations of machine learning for understanding data. It researches and develops machine learning techniques that express analysis results obtained from data as knowledge in order to understand the big picture of complex data, along with the optimization algorithms needed for them.
*Illustrative imageMachine Learning for Understanding Data
The lab focuses on data-driven machine learning that captures the big picture of complex data, and conducts research using traffic data and web marketing data. It places importance on being able to compare and explain learning results, and on being able to predict how things change when an intervention is made.
*Illustrative imageInterpretable Predictive Models
The lab focuses on generalized additive models and models based on combinations of two variables, as predictive models whose predictions can come with explanations that people can understand. It aims to develop learning methods that are more efficient than optimization based on coordinate descent, as well as models that are even easier to interpret.
*Illustrative imageExploring Causality through Information Theory
Based on the idea that model selection grounded in information theory is useful for identifying the causal mechanisms underlying data, the lab develops methods for estimating causal mechanisms from data. It aims to develop causal discovery methods that can be applied to more complex and larger-scale data.
