In this article, we propose a new classification method called fuzzy canonical discriminant analysis (FCDA) based on the Fisher's canonical discriminant analysis (CDA) to deal with some vagueness in natural and social science and to improve its prediction accuracy. By establishing the fuzzy canonical discriminant function and triangular function transformation, we obtain the estimators of parameters. We also design an efficient algorithm for calculation of the parameters. We compare it with CDA using the original Iris data, samples of the Iris data, and seven other popular data sets. The results confirms that the FCDA is an effective tool in prediction and is better than the CDA.
