FACIAL AGE ESTIMATION BASED ON IMPROVED LDL ALGORITHM
The change of facial age features is orderly and slow,and the facial age features of the same person with similar age are similar.Age estimation based on marker distribution learning is a method designed by using this feature,which realizes the transformation of learning task from single target age prediction to age marker distribution vector prediction.It solves the problem of face age estimation that the data is not comprehensive to a certain extent.However,the existing label distribution learning based on the maximum entropy regression model has some problems,such as unable to build a unified label distribution prediction model and long computation time.Another algorithm based on neural network is prone to over fitting and the structure of neural network is not easy to understand.To solve these problems,label distribution learning(LDL)based on kernel partial least squares regression model is used to solve the problem of face age estimation.The kernel partial least squares regression model has no hypothesis for data distribution and can solve nonlinear problems.The experimental results on FG-NET and MORPH Ⅱ data set show that compared with other comparison methods,this method has smaller age estimation error and higher computational efficiency.
