... in- terpretation, and it is statistically consis- tent. It is substantially faster than maximum (conditional) likelihood estimation of condi- tional random fields (Lafferty et al., 2001; an order of magnitude ... Indeed, M -estimation is consider- ably easier to implement than conditional estima- tion. Both require feature counts from the train- ing data; M -estimation replaces repeate...
