The modulation of color temperature of illumination always use the red or yellow LED to adjust the white LED. The research was to use the Artificial Neural Network to estimate the chromaticity coordinates of 3x2 LED array mixing by red and yellow LEDs. There are four algorithm methods: Levenberg-Marquardt (LM), Broyden Fletch Goldfard Shan no (BFGS), Fletcher-Reeves Conjugate Gradient (FRCG) and Scaled...
In this paper, a classification framework is developed to address the issue that empirical determination of the parameters and their values typically makes a classification framework less adaptive and general to different data sets and application domains. Experimental results show that our proposed framework achieves (1) better performance over other comparative supervised classification methods,...
