Abstract

L. Breiman recently introduced the concept of random forests (randomly constructed collection of decision trees) for classification. We have modified the method for regression and applied it to language modeling for speech recognition. Random forests achieve excellent results in both perplexity and error rate. They can be regarded as a language model in HMM form and have interesting properties that achieve very robust smoothing.
