Deep learning is one of the most popular domains in the AI space that allows you to develop multi-layered models of varying complexities. The cost function is the measure of “how good” a neural network did for its given training input and the expected output. Higher-level features are derived from lower level features to form a hierarchical representation. The brain contains billions of neurons with tens of thousands of connections between them. Compiling the model uses the efficient numerical libraries under the covers (the so-called backend) such as Theano or TensorFlow. Now that we have seen how the inputs are passed through the layers of the neural network, let’s now implement an neural network completely from scratch using a Python library called NumPy.
