Note: In our second tutorial on neural networks, we dive in-depth into the limitations and advantages of using neural networks. We show how to implement neural nets with hidden layers and how these lead to a higher accuracy rate on our predictions, along with implementation samples in Python on Google Colab. Neural networks form the base of deep learning, which is a subfield of machine learning, where the structure of the human brain inspires the algorithms. Neural networks take input data, train themselves to recognize patterns found in the data, and then predict the output for a new set of similar data. Therefore, a neural network can be thought of as the functional unit of deep learning, which mimics the behavior of the human brain to solve complex data-driven problems.

After reading the first article, we saw that we had only 1 phase of execution there. In that phase, we find the updated weight values and rerun the code to achieve minimum error. However, things are a little spicy here. The execution in a multilayer neural network takes place in two-phase. In phase-1, we update the values of weight_output (weight values for output layer), and in phase-2, we update the value of weight_hidden ( weight values for the hidden layer).

In the first part of our tutorial on neural networks, we explained the basic concepts about neural networks, from the math behind them to implementing neural networks in Python without any hidden layers. We showed how to make satisfactory predictions even in case scenarios where we did not use any hidden layers. However, there are several limitations to single-layer neural networks. In this tutorial, we will dive in-depth on the limitations and advantages of using neural networks in machine learning. We will show how to implement neural nets with hidden layers and how these lead to a higher accuracy rate on our predictions, along with implementation samples in Python on Google Colab.

Note: In an upcoming second tutorial on neural networks, we will show how we can add hidden layers to our neural nets.

The first thing that comes to our mind when we think of "neural networks" is biology, and indeed, neural nets are inspired by our brains.
