On the optimization of margin distribution
Web10 de nov. de 2013 · By optimizing margin distribution of the final decision function, we derive the weights of different granularity. The granularity with the largest weight is considered to be optimal. In addition, weights can be used to rank the granularity or combine recognition results of different granular spaces. Webalgorithm for linear classiers, MDO (Margin Distribution Optimization), that attempts to be optimal with respect to the margin distribution based complexity measure. Specif-ically, we rst argue that this complexity measure can be used for model selection. Empirically, we show that the margin distribution of the data with respect to a classier
