1. What Is Viterbi Decoding? Viterbi is a dynamic programming algorithm that finds the most likely sequence of hidden states in a Hidden Markov Model (HMM) given an observation sequence. 2. Why Not Brute Force? Viterbi: $ O(T N^2) $ → polynomial, feasible 3. HMM Components (Your Paper) Component Formula Meaning Emission $ p(x_t | … Continue reading Viterbi Decoding Algorithm: Complete Technical Explanation
