HMM_Viterbi_BaumWelch

Overview

Hidden Markov Models (HMMs) are a powerful statistical tool for modeling dynamic systems where the system's state is not directly observable. This particular implementation focuses on two essential algorithms within HMMs: the Viterbi algorithm and the Baum-Welch algorithm, offering a clear and concise Python 3.6+ solution powered by Numpy. For anyone keen on diving into the world of HMMs, this repository serves as an excellent springboard for both understanding and practical application.

The implementation is straightforward, making it accessible for users who may be new to the concepts behind HMMs. It provides not only code but also example scenarios, like a weather prediction model, to help contextualize the theoretical aspects of these algorithms. Such practical examples are crucial for grasping the utility of HMMs in real-world applications.
