| Description: |
I'm in the middle of a homework that uses HMM's and the forward/backward algorithm. I understand the forward pass, but can't get the backward pass right. All of the calculations have to be in log-space because that's the way it's coded up.
- forward pass
- prob(dest_state) = log_plus(prob(source_state)*prob(state_trans), prob(dest_state))
- backward pass
- ?
