I am aware of maths for ml, python and few of the libraries in python. i am unable to understand the code in C2_W1_Lab01_Neurons_and_Layers in which tensor flow and keras is used mostly.firstly i am unaware of the functions in the tensor flow like:
from tensorflow.keras.layers import Dense, Input
from tensorflow.keras import Sequential
from tensorflow.keras.losses import MeanSquaredError, BinaryCrossentropy
from tensorflow.keras.activations import sigmoid
what should i do now?
