Build Neural Networks In Python From Scratch. Step By Step!
Learn how to build Neural Networks from scratch using Python. Understand concepts like back propagation, gradient descent, and hidden layers. Perfect for developers who want to learn the mechanics of neural networks without relying on libraries or frameworks. Start from the absolute beginning and progress step by step. No need for external packages. Ideal for beginners with little pre-knowledge. Taught by a senior software engineer with 25 years of experience.
What you’ll learn
- The basic functions for any neural network, by coding linear regression, cost functions and back propagation
- Understand the properties of neural networks by adjusting learning rates and biases
- Train a network by implementing a gradient descent algorithm
- Normalizing inputs for multi-input networks
- Create classification networks by implementing multiple output neurons and activation
- Improve network accuracy by implementing hidden layers for non-linear data
You will learn how to build Neural Networks with Python. Without the need for any library, you will see how a simple neural network from 4 lines of code, evolves into a network that is able to recognize handwritten digits.
During this process, you will learn concepts like: Feed forward, Cost functions, Back propagation, Hidden layers, Linear regression, Gradient descent and Matrix multiplication. And all this with plain Python.
Target audience
Developers who especially benefit from this course, are:
Developer who want to learn the mechanics of neural networks
Developers who want to avoid using neural network libraries and frameworks
Or developers who use frameworks but want to learn the meaning of the individual network parameters
Challenges
Many tutorials claim to start from scratch, but import external libraries or rapidly type in code and before executing even once, you are looking at 50 lines of code. When finally the code is run, you are totally lost and still stuck trying to understand line 3.
This causes many students to give up learning Neural Networks.
This course is different! It starts with the absolute beginning and each topic is a continuation of a previous example. This way, you will learn neural networks from the ground up, step by step.
What can you do after this course?
You understand neural network concepts and ideas, like backward propagation and gradient descent.
You are able to build a neural network in any programming language of choice, without the help of frameworks and libraries.
You understand how to better configure the network by plugging in different cost functions and adding hidden layers.
