Evaluation of Discrete Models
Instructions
2.
Test this implementation using the hand-calculated results for question 1. The results produced by
your Python code must match the hand-calculated results.
Create your own 3 observation vector and calculate P(O2) by hand. Test your forward algorithm
implementation using this vector. The results produced by your code must match the hand-
calculated results.
4. Create an observation vector of at least 7 elements. Test your forward algorithm using
this vector.
3.
<Calculate forward probability here>
