MIDI Score : Length : 1 second Hmmtrain : – unknown states – initial guesses for TRANS and EMIS – hmmtrain (seq, TRANS_GUESS, EMIS_GUESS)
TRANS_GUESS : 12x12 – C → D, D → E, E → F, F → G0.8 – Othersrandom EMIS_GUESS : played or not – 0.9 vs. 0.1 – Not accepted
hmmtrain (seq, TRANS_GUESS, EMIS_GUESS) seq – Source – Output of band-pass filter Hmmtrain will use algo. – BaumWelch : hmmdecode Calculates the posterior state probabilities of a sequence of emissions – Viterbi : hmmviterbi
hmmtrain The results of models have big difference than the guess! Can’t use the results to get the great states when running Viterbi algorithm.
Future Works Finish the 3 rd version. Modify the guess models to get the better result!
