... because the transition information is crucial for the two tasks, and the assumption behind C ARPEDIEM is violated. In contrast, the proposed algorithms per- formed reasonably well for all three tasks, ... λ(y n ) and ¯ λ(y n ) by using the forward and backward Viterbi algorithm, respec- tively. In the search step immediately following initialization, we perform the forward Viterbi al- gor...
