Looking for uses of the Forward Algorithm

I'm looking for some realworld applications of the Forward Algorithm as proposed by Rabiner (forward Algorithm on wikipedia).

I would prefer applications where the executing time is important.

Solution

  • If you mean the forward-backward algorithm, that's applied inside the Baum-Welch algorithm for training HMMs, which is used in various fields such as NLP (part-of-speech tagging, speech recognition) and bioinformatics.
