What is upsampling method?

Upsampling or Oversampling refers to the technique to create artificial or duplicate data points or of the minority class sample to balance the class label. There are various oversampling techniques that can be used to create artificial data points.

What is upsampling factor?

Upsampling by a factor of inserts zeros between every two samples of a discrete-time sequence. This expansion in time causes a contraction in frequency and the appearance of spurious spectral components, necessitating filtering after upsampling. The three sets of controls let you vary the path of the input sequence.

What is upsampling and down sampling?

Up-Sampling is a "Zero-Padding Procedure" that increase the number of samples of a DT signal. More specificals, when up sampling, zeros are added between the samples of a signal. Down-Sampling is to decrease the sample size.

What is the use of upsampling?

When upsampling is performed on a sequence of samples of a signal or other continuous function, it produces an approximation of the sequence that would have been obtained by sampling the signal at a higher rate (or density, as in the case of a photograph).
