WebOct 1, 2024 · In down-sampling we start with a constant time signal x (t) and convert it into a succession of tests x [n], in decimation we start with a discrete-time signal x [n] and convert it into another discrete-time signal y [n], which comprises of sub-tests of x [n]. We will be using the decimate () and stem () function.

Here I use initial_split () to create a testing and training dataset. The resulting object is called an rsplit object and contains the original data and information about whether a record goes to testing or training. This object is not a flat dataframe but rather a nested list.

The advantage of having both the master and the "access" files differ only in resolution, but at the same height and width is they can be used as a true "proxy."
