Summary
The authors wanted to train a language model that used fewer parameters than an n-gram model, but still performed well. They developed aggregate and mixed-order markov models. While similar in some ways (mainly their Markovian properties), the new methods give fewer words 0 probability
Future Work
Aggregate Markov models can kinda be viewed as approximations of a full bigram model. In this way, the method is similar to SVD decomposition, which might be related. The classic question of generative vs discriminative models comes up. The authors argue that their generative model is fine because they train the mixture of generative models such that they model reality. Theirs models also train in a fraction of the time spent training Rosenfeld's models.
