Hidden Markov Model
Last semester I found Hidden Markov Model in "Mathematics & Statistics for Computing" class, this semester I found it in "Computational Intelligence" class, next semester I'll find it in "Pattern Recognition" class. Even in a song, I find Hidden Markov Model.
Look at the lyrics I put on may last post...
Like the flower and the scent of summer,
Like the sun and the shine,
Well the truth may come in strange disguises,
Send the message to your mind
I think it's the most poetic and beautiful expression of Hidden Markov Model!
