Linear dimensionality reduction for classification via a sequential Bayes error minimisation with an application to flow meter diagnostics

作者:

Highlights:

• We propose a supervised linear dimensionality reduction algorithm.

• The algorithm reduces the dimensionality of data to K−1 for the K-class problem.

• The linearly reduced data is well-suited for Bayesian classification.

• Experiments on UCI datasets are performed for the proposed and existing algorithms.

• The applicability of the algorithm to flow meter diagnostics is also demonstrated.
