SVM增量式学习的自适应与优化的MATLAB代码

基于支持向量机的自适应与优化，包含论文SVM Incremental Learning Adaptation and Optimization - Diehl and Cauwenberghs - 2003的文章和源代码

% BOOKKEEPING - Updates the status of example indss and modifies the corresponding
%               coefficient a（indss） in certain cases to avoid numerical errors.
%
% Syntax: [indcoi] = bookkeeping（indsscstatusnstatus）
%
%     indco: matrix row/col to remove from Rs and Q if removing a margin vector
%         i: when i > 0 the i-th element was removed from ind{RESERVE}
%     indss: the example changing status
%   cstatus: current status of the example
%   nstatus: new status of the example
%
%            example status values:
%            1: margin vector
%            2: error vector
%            3: reserve vector
%            4: unlearned vector
