Principal component analysis (PCA) has been widely used in many applications. In this paper, we present the problem of computational complexity in prediction, which increases as more input of predicting event’s information is provided. We use the information theory to show that the PCA method can be applied to reduce the computational complexity while maintaining the uncertainty level of the prediction. We show that the percentage increment of uncertainty is upper bounded by the percentage increment of complexity. We believe that the result of this study will be useful for constructing predictive models for various applications, which operate with high dimensionality of data. 2018-01-24T04:43:39Z 2018-01-24T04:43:39Z 2015-01-01 Book Series 18678211 2-s2.0-84961366765 10.1007/978-3-319-15392-6_14 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84961366765&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/44491
