Abstract
With the increase of economic globalization and evolution of information technology, high-dimensional stock data reduction has become an essential part as pre-processing technique for data compression and effective future data mining process. In this paper, we study the effect of dimension reduction technique, which is commonly used for correlated multi-dimensional data. We use PCA as one of the representatives of the reduction techniques. And we improve the results of Principle Component Analysis (PCA) by using proper pre-processing approach based on Perceptually Important Point (PIP) algorithm. By using our approach, we can improve the efficiency of dimension reduction to stock data. Encouraging experiment is reported from the tests that our approach can provide a much higher reservation ratio for the reduced multi-dimensional stock data.
