- First we re-split out data into a training and a test set with the
corresponding labels. We can then simply transform
- the numpy array of the training data back to SystemDS matrix by using
"sds.from_numpy()".
- The SystemDS scale function takes a matrix as an input and returns
three output parameters:
- # Y Matrix --- Output feature matrix with K
columns
- # ColMean Matrix --- The column means of the input,
subtracted if Center was TRUE
- # ScaleFactor Matrix --- The Scaling of the values, to
make each dimension have similar value ranges
- If we want to retransform a SystemDs Matrix to a Numpy array we can do
so by using the np.array() function.
