WebMar 28, 2024 · Since HMM is based on probability vectors and matrices, let’s first define objects that will represent the fundamental concepts. To be useful, the objects must reflect on certain properties. For example, all elements of a probability vector must be numbers 0 ≤ x ≤ 1 and they must sum up to 1.
