In This Section, We Will Go Through The Steps Involved In Implementing The Viterbi Algorithm In Python.

It helps us determine the most likely sequence of hidden states given the observed data. Web the viterbi algorithm is a dynamic programming algorithm for obtaining the maximum a posteriori probability estimate of the most likely sequence of hidden states—called the viterbi path—that results in a sequence of observed events. With these defining concepts and a little thought, the viterbi algorithm follows: Store l (c k+1) and the corresponding survivor s (c k+1 ).

Web The Viterbi Algorithm Is A Sequence Prediction Method That Works Well With Hidden Markov Models.

Handle the initial state 4: Therefore, if several paths converge at a particular state at time t, instead of recalculating them all when calculating the transitions from this state to states at time t+1, one can discard the less likely paths, and only use the most likely one. Despite being one of the most important algorithms of the 20 th century, the viterbi algorithm [1], [2], [3], like. It works by asking a question:
