Cumulative training margin dis(cid:173) tributions for AdaBoost versus our "Direct Optimization Of Margins" (DOOM) algorithm. The dark curve is AdaBoost, the light curve is DOOM. DOOM sacrifices significant training er(cid:173) ror for improved test error (hori(cid:173) zontal marks on margin= 0 line)_
