Naive Bayes A linear classifier Generative model: model \(p(X,y)\)
We have observed variable \(x\), latent varivable \(z\) and parameters \(\theta\). The complete log likelihood should be \(l(\theta;x,z) = \log p(x,z | \the...

Clustering is aimed at grouping set of objects that have similar “properities”. There are many different ways to define the distance for clustering. The famo...

When using Matlab to verify “Convolution in time domain is multification in frequency domain”, simply doing fft2 is wrong.

We know that wavelet transform comes from STFT by changing a single windowing function to a set of windowing functions. \(X(t,\omega) = \int_{-\infty}^{\i...
Why use STFT? We wants to know the frequency components at each time point. Solution: we perform FFT on small blocks. \(X(t,\omega) = \int_{-\infty}^{\...
Why use DCT DTFS/FFT (We will not detail into the difference between these two at this moment.) use $e^{jwt}$ as the base. And if $x(t)$ is real and even,...
