Description
Attention: Please read careful about the description, especially the last paragraph, before buying this course.
The Wavelet Transforms (WT) or wavelet analysis is probably the most recent solution to overcome the shortcomings of the Fourier Transform (FT). WT transforms a signal in period (or frequency) without losing time resolution. In the signal processing context, WT provides a method to decompose an input signal of interest into a set of elementary waveforms, i.e. “wavelets”, and then analyze the signal by examining the coefficients (or weights) of these wavelets.
Wavelets transform can be used for stationary and nonstationary signals, including but not limited to the following:
noise removal from the signals
trend analysis and forecasting
detection of abrupt discontinuities, change, or abnormal behavior, etc. and
compression of large amounts of data
the new image compression standard called JPEG2000 is fully based on wavelets
data encryption, i.e. secure the data
Combine it with machine learning to improve the modelling accuracy
Therefore, it would be great for your future development if you could learn this great tool. Practical Python Wavelet Transforms includes a series of courses, in which one can learn Wavelet Transforms using word-real cases. The topics of this course series includes the following topics:
Part (I): Fundamentals
Discrete Wavelet Transform (DWT)
Stationary Wavelet Transform (SWT)
Multiresolutiom Analysis (MRA)
Wavelet Packet Transform (WPT)
Maximum Overlap Discrete Wavelet Transform (MODWT)
Multiresolutiom Analysis based on MODWT (MODWTMRA)
This course is the fundamental part of this course series, in which you will learn the basic concepts concerning Wavelet transforms, wavelets families and their members, wavelet and scaling functions and their visualization, as well as setting up Python Wavelet Transform Environment. After this course, you will obtain the basic knowledge and skills for the advanced topics in the future courses of this series. However, only the free preview parts in this course are prerequisites for the advanced topics of this series.
