Latest Patents

Takeuchi's latest patents include innovative devices and methods for outlier determination and detection. His outlier detection device is designed to identify abnormal data within a dataset. This device features an outlier rule preservation unit, a filtering unit, a degree of outlier calculation unit, a sampling unit, and a supervised learning unit. The supervised learning unit generates new rules that characterize abnormal data through supervised learning, based on labeled datasets. These new rules are then added to the existing rules in the outlier rule preservation unit, allowing for continuous updates. The filtering unit utilizes these rules to assess whether each data point is abnormal. Additionally, the degree of outlier calculation unit compares abnormal data against normal data to determine the degree of abnormality.

Another notable patent involves a degree of outlier calculation device and a probability density estimation device. This technology calculates the degree of outlier for input data by measuring changes in learned probability density before and after data input. The probability density estimation device effectively estimates the probability distribution of potentially unfair data while processing large volumes of data.
