Hi, all:
about HMM Evaluation question:
There are 3 methods to carry out HMM evaluation.
1) forward algorithm
2) backward algorithm
3) forward-backward algorithm
Sometimes, forward algorithm and backward algorithm may not give out the same result.
Can anybody (mathematician) help to...
Sorry for my stupidity.
Your word "multiply" hints me. !
This is a "element-wise" multiplication! Right? Yes, it should be.
Thanks for your answering to clarify my doubts.
Best Regards

Short Time Fourier Transform -- invertible?
On Wikipedia,
http://en.wikipedia.org/wiki/Short-time_Fourier_transform"
However, it's also said
That is to say, Gabor is invertible, it's able to obtain the original signal, but modulated.
original signal is obviously x(t),
w(t-τ)...
