Introduction to Neural Networks

1. Concept of Neural Network

First, we will discuss what a neural network is and how it works. And also consider the scope of its application.

What is a Neural Network?

Neural Network Structure

What is a Neuron?

Activation Functions

Forward and Backward Propagation

Applications of Deep Learning in the Real World

2. Neural Network from Scratch

Next, we will try to build our own neural network and see how efficiently it copes with learning. We will also consider a ready-made solution from the scikit-learn library.

Single Neuron Implementation

Model Training and Evaluation

Neural Network with scikit-learn

3. Conclusion

Finally, we will give you some additional useful information on how to understand which model to use and what types of neural networks there are. To complete the course, you will be tested on your acquired knowledge.
