C2_W1.pdf → Slide 47 is old slide and data is not matching.

x = np.array([[200.0, 17.0]])
layer_1 = Dense(units=3, activation=‘sigmoid’) 
a1 = layer_1(x) # 1 x 3 matrix
> tf.Tensor([[0.2 0.7 0.3]], shape=(1, 3), dtype=float32)
a1.numpy()
> array([[1.4661001, 1.125196 , 3.2159438]], dtype=float32

both arrays should have same values.

Video has corrected content but slide is incorrect.
