| Outline of Final Research Achievements |
This work proposes efficient computing methods for image recognition by neural network processors, in which inaccurate computation is positively utilized based on the observation of the calculation redundancy in the recognition process. For the inaccurate computation, approximate computing and low-voltage operation of the circuits can be used to improve their energy efficiency. However, they may affect the recognition performance because of the calculation errors. In this work, novel algorithms to mitigate the calculation errors are proposed, and they achieved the energy efficiency improvement of the neural network processor while keeping the recognition accuracy.
