Eugenie Giesbrecht updated UIMA-605:
------------------------------------
Attachment: Viterbi.java
This version was changed to perform Viterbi calculations with LOGs instead of
pure probabilities. This is necessary to avoid double underflow in Java (as the
longer is the sequence to tag, the smaller is the probability - e.g. the domain
of 1.7296611368116755E-304), as well as to make calculations more robust and
quick (as we use summations with logs instead of multiplications in the
original Viterbi).
