Now, we define a function called sample_points for generating our input (x, y) pairs. It takes the k parameter as input, which implies the number of (x, y) pairs we want to sample:

def sample_points(k):
    x = np.random.rand(k,50)
    y = np.random.choice([0, 1], size=k, p=[.5, .5]).reshape([-1,1])
    return x,y

The preceding function returns the following output:

x, y = sample_points(10)
print x[0]
print y[0]
