"Visualizing invisible changes." It is a high-precision change detection technology using teacher-assisted data synthesis.
We would like to introduce our "High-Precision Change Detection Technology Using Synthetic Labeled Data." This method allows for the easy synthesis of labeled data to detect subtle changes hidden in time series data. We have achieved the detection of change points, which was previously difficult, by synthesizing labeled data from existing data. This technology can be applied across a wide range of fields, from manufacturing to infrastructure and health management. 【Features】 ■ Easily prepare training data by synthesizing labeled training data from existing data. ■ Capable of accurately detecting minute changes compared to conventional technologies. *For more details, please download the PDF or feel free to contact us.

Applications/Examples of results
[Demonstration Example] Detection of Weather Observation Station Relocation Using 26 years of temperature data from Kyushu, training data with teacher signals was synthesized only within the same prefecture, and supervised learning was conducted using a recurrent neural network (NN). Using the recurrent NN trained with data simulating movements of approximately 10 km, actual weather observation data was validated. ⇒ The recurrent NN detected a relocation of about 900 m for the Tokyo observation station and a movement of about 200 m for the Kiire observation station. ⇒ It was able to detect minute changes beyond the 10 km variations used in the training data. [Expected Applications] Manufacturing and Machinery: "Utilizing data on power consumption, vibrations, and sounds" ⇒ Anomaly detection for machine failures, predictive maintenance Infrastructure: "Data on vibrations, sounds, and traffic volume" ⇒ Monitoring of bridges, tunnels, roads, etc. Healthcare: "Vital data such as blood pressure and body temperature" ⇒ Monitoring of vital data, health management
