Study the following sections from Chapter 15:

• Sections 15.1-2 - Study these sections carefully. They are the focus of our work on this chapter.
• Section 15.3 - Review the opening paragraphs of this section, focusing on the structure of Hidden Markov Models (HMMs). The remainder of the section discusses how HMMs are implemented, which can be helpful in understanding the HMM module you’ll use in the lab.
