Outline
• Introduction of Viterbi Algorithm• Example• Reference
Introduction of Viterbi Algorithm
• a dynamic programming algorithm for finding the most likely sequence of hidden states called the Viterbi path.
• HiddenMarkovModel
Example O = Walk->Walk->Shop->Clean
Example O = Walk->Walk->Shop->Clean
Example O = Walk->Walk->Shop->Clean
Example O = Walk->Walk->Shop->Clean
ExampleO = Walk->Walk->Shop->CleanS = Sunny->Sunny->Rainy->Rainy
