This text realizes optimal linear combination method basing on recognition confidence . this method advances recognition confidence scaling recognition performance for each sample . in train phase divide train samples into different areas with their recognition confidence and apply olc in different areas to get multi - classifier combination power vector 此方法提出了用于衡量分类器对单个样本识别性能的判决可靠度,在训练阶段根据各分类器的判决可靠度把训练样本分成不同的区域,从而可以在不同的区域里应用最优线性集成方法得出各区域的分类器组合权值。
