Viterbi algorithm

The Viterbi algorithm is a method used to find the most likely sequence of hidden states in statistical models, especially in scenarios like speech recognition, DNA sequencing, and communication systems. Imagine you’re trying to trace the steps someone took based on clues left behind, but you don’t see their path directly. The Viterbi algorithm analyzes all possible paths and scores them based on how well they match the clues, ultimately selecting the best path that represents the most probable sequence of events. This helps in decoding information and making accurate predictions in uncertain contexts.
