Fisher discriminant analysis with l1-norm

WebOct 3, 2013 · A novel discriminant analysis criterion is derived in this paper under the theoretical framework of Bayes optimality. In contrast to the conventional Fisher's discriminant criterion, the major novelty of the proposed one is the use of L1 norm rather than L2 norm, which makes it less sensitive to the outliers. With the L1-norm … Webhave a tractable general method for computing a robust optimal Fisher discriminant. A robust Fisher discriminant problem of modest size can be solved by standard convex optimization methods, e.g., interior-point methods [3]. For some special forms of the un-certainty model, the robust optimal Fisher discriminant can be solved more efficiently …
