Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Linear discriminant analysis(LDA) is a traditional dimension reduction method which finds projective directions to maximize separability beten classes. Hover, when the number of labeled data points is small, the performance of LDA is degraded severely. ,  propose two improved methods for LDA which utilizes abundant unlabeled data. Instead of using all the unlabeled data as in most of semi-supervised dimension reduction methods,  select confident unlabeled data and develop extended LDA algorithms. In the first method, a graph-based LDA method is developed to utilize confidence scores for chosen unlabeled data so that unlabeled data with a low confidence score contributes smaller than unlabeled data with a high confidence score. In the second method, selected unlabeled data points are used to modify the centroids of classes in an objective function of LDA. Extensive experimental results in text classification demonstrates the effectiveness of the proposed methods compared with other semi-supervised dimension reduction methods.
