AB  - A voltammetric electronic tongue (VE-tongue) was developed to discriminate the 
      difference between Chinese rice wines in this research. Three types of Chinese 
      rice wine with different marked ages (1, 3, and 5 years) were classified by the 
      VE-tongue by principal component analysis (PCA) and cluster analysis (CA). The 
      VE-tongue consisted of six working electrodes (gold, silver, platinum, palladium, 
      tungsten, and titanium) in a standard three-electrode configuration. The 
      multi-frequency large amplitude pulse voltammetry (MLAPV), which consisted of 
      four segments of 1 Hz, 10 Hz, 100 Hz, and 1000 Hz, was applied as the potential 
      waveform. The three types of Chinese rice wine could be classified accurately by 
      PCA and CA, and some interesting regularity is shown in the score plots with the 
      help of PCA. Two regression models, partial least squares (PLS) and back-error 
      propagation-artificial neural network (BP-ANN), were used for wine age 
      prediction. The regression results showed that the marked ages of the three types 
      of Chinese rice wine were successfully predicted using PLS and BP-ANN.
