摘要： Discrimination of wild and cultivated mushrooms is important for their quality assessment. In this study, data fusion of infrared and ultraviolet spectroscopies combined with support vector machine or random forest were applied for the discrimination of wild and cultivated W. cocos and P. portentosusis. For the low- and mid-level data fusion classification models, the accuracies of validation set are 90.91% and 98.70%, respectively. However, the parameter c is too large which means the models are unreliable. For the high-level data fusion, the results showed that the accuracy of validation set is 100% and the sensitivity and specificity increased significantly compared to the single technique. Therefore, high-level data fusion combined with random forest is an effective method for the discrimination of wild and cultivated grown W. cocos and P. portentosus, and may be applied for protecting the steady development of the edible mushroom market.
