Multiplication Algorithm

The sound denoising algorithm is based on the popular spectral subtraction technique. Based on the spectrum of the vuvuzela sound, this denoising technique simply computes an antenuation map in the time-frequency domain. Then, the audio signal is restored by computing the inverse STFT. See [1-3]...

This is a small example code for "Steepest Descent Algorithm". It implements steepest descent Algorithm with optimum step size computation at each step. The code uses a 2x2 correlation matrix and solves the Normal equation for Weiner filter iteratively.Reference:Adaptive Filter Theory 3rd...

The submission considers a case where you deduce what weather it is given the status of a shirt that is hung outside. The weather could be Sunny, cloudy, Rainy and the shirt could be dry, dryish, damp etc. Now given some probability matrices (The initial probability of the weather, the transition...
