The lab explores the classification of imbalanced data using databases and data mining.
AboutAbout the lab
Data management and the classification of imbalanced data.
The lab of Associate Professor Takahiro Komamizu lists databases and data mining as its research fields and studies data management and classification.
The research keywords listed are imbalanced data classification, Linked Open Data, analytical processing, and multimedia data management.
The lab also works on managing data related to Japanese law.
Key terms
- Class imbalance
- A situation in which the amount of data differs greatly between the groups (classes) to be classified. It is a factor that lowers performance in many methods
- Resampling
- A method of balancing the amount of data by increasing the data in the minority class or reducing the data in the majority class
- Metric learning
- A method that learns the distance used to measure how close data points are, so that it suits classification
ResearchResearch themes
Building on databases and data mining, the lab studies methods for classifying and managing data. Its research introduction page lists topics such as imbalanced data classification, the management of Linked Open Data, and the management of data related to law.
