Outline of Final Research Achievements |
We proposed a tiny learning machine : "limited general regression neural network (LGRNN)", which is inspired by insect's brain. LGRNN learns new instances one by one, and selects important instances, and store them into a limited capacity. This ability is realized by choosing one of several learning options adaptively by estimating an evaluation function, which predicts expected error due to the execution of each learning option. The proposed method was applied to a micro-converter of photovoltaics, which improves the electricity generation ability of solar panels. The system consists of a conventional hill climbing mechanisum for finding the maximum power point(MPP), and LGRNN. Normally, the device tracks the MPP using the conventional method, while the LGRNN learns the relationships between the current magnitude of solar-irradiation, tempeleture and MPP. When the solar-irradiation changes abruptly, however, LGRNN yields the predicted MPP for controling the chopper circuit quickly.
