So let’s start by creating the data of 1000 data points, 10 features, and 3 target classes. 1 2 3 4 Instantiate a prng=numpy.random.RandomState (RANDOM_SEED) instance, then pass that as random_state=prng to each individual function. If you just pass RANDOM_SEED, each individual function will restart and give the same numbers in different places, causing bad correlations. – Robert Kern.
