Thus, the training set includes 75 samples in total, and the test set includes 25 samples in total. We ranked the expected output [http://www.selleckchem.com/products/GDC-0941.html Akt inhibitor] of five storage times for each storage environment from small to large. They are (1, 0, 0, 0, 0), (0, 1, 0, 0, 0), (0, 0, 1, 0, 0), (0, 0, 0, 1, 0), (0, 0, 0, 0, 1). After repeated training, the model parameters and recognition accuracy are given in Table 3. The classification accuracy of training sets of the room temperature environment storage group, the refrigerator environment storage group and the controlled-atmosphere storage group are 89.33%, 100% and 100%, respectively. The classification accuracy of test sets of the room temperature environment storage group, the refrigerator environment storage group and the controlled-atmosphere storage group are 52%, 88% and 96%, respectively. Thus, the storage time of the refrigerator environment and the controlled-atmosphere stored litchi can be classified effectively via the electronic nose. However, the storage time classification effect of litchi stored in the room temperature environment is still poor. Table 3 BPNN classification results of storage times of litchi stored in three environments. 3.5. CCA for Correlation Analysis between Electronic Nose Data and Hardness of Litchi In this experiment, the CCA was applied to test the correlation between electronic nose data and hardness of litchi stored in three environments, and the ��canoncorr�� function command of Matlab was used to perform the CCA analysis. [https://en.wikipedia.org/wiki/Azastene Azastene] The CCA plots (Figure 3) illustrate a strong linear correlation between the canonical correlation variable of the sensor response data and the canonical correlation variable of the hardness values, indicating that the electronic nose response were linearly correlated with hardness values of litchi stored [http://www.selleckchem.com/products/ve-821.html www.selleckchem.com/products/ve-821.html] in the three environments. The |r| values between the electronic nose data and the hardness of litchi stored in the room temperature environment, the refrigerator environment and the controlled-atmosphere environment are 0.5919 (sig = 1.29 �� 10?2), 0.7104 (sig = 8.85 �� 10?3) and 0.7439 (sig = 8.04 �� 10?3), respectively. Thus, CCA results show a significant correlation (|r| > 0.5, sig 0.7, sig
