ML01 ex05 (z_score): incoherent example
- Day: 06
- Exercise: 05
There are 3 minors issues:
Turn in filename
The subject header says: Files to turn in : z_score.py
But the instructions says: In the zscore.py file, write the zscore function (without the underscore)
Undefined numpy
In the examples, X is defined while calling numpy, but Y is defined while calling np
Mismatching Y shape
Still in the examples, Y is declared as follows:
Y = np.array([2, 14, -13, 5, 12, 4, -19]).reshape((-1, 1))
Thus its shape is (2, 1) and not (2, ) as X.
The problem is that the expected value is:
array([ 0.11267619, 1.16432067, -1.20187941, 0.37558731, 0.98904659, 0.28795027, -1.72770165]) which shape is (7, ), IMO it should be (7, 1) so the zscore function can copy the incomming array's shape.
