Course Overview

Master Neural Networks: Build with JavaScript and React

Build and integrate Neural Networks in Web Apps with JavaScript, React, and Node.js. From Scratch with Math Included.

Welcome to Master Neural Networks: Build with JavaScript and React. This comprehensive course is designed for anyone looking to understand and build neural networks from the ground up using JavaScript and React.


What You'll Learn:

  1. Introduction to Neural Networks

    • Understand the basics of perceptrons and their similarities to biological neurons.

    • Learn how perceptrons work at a fundamental level.

  2. Building a Simple Perceptron

    • Code a perceptron to classify simple objects (e.g., pencils vs. erasers) using hardcoded data.

    • Implement a basic perceptron from scratch and train it with sample inputs and outputs.

    • Draw graphs and explain the steps needed, including defining weighted sums and activation functions.

  3. Perceptron for Number Recognition

    • Advance to coding a perceptron for number recognition using the MNIST dataset to identify if a number is 0 or not.

    • Train the perceptron using the MNIST dataset, optimizing weights and biases.

    • Learn techniques to calculate accuracy and handle misclassified data.

    • Save and export the trained model for use in web applications.

  4. Parsing and Preprocessing MNIST Data

    • Learn to parse and preprocess MNIST data yourself.

    • Understand the file formats and the steps needed to convert image data into a usable format for training.

  5. Building a Multi-Layer Perceptron (MLP)

    • Develop a more complex MLP to recognize digits from 0 to 9.

    • Implement training algorithms and understand backpropagation.

    • Explore various activation functions like ReLU and Softmax.

  6. Practical Implementation with JavaScript and React

    • Integrate neural networks into web applications using JavaScript, React, and Node.js.

    • Build and deploy full-stack applications featuring neural network capabilities.

    • Create a React application to test and visualize your models, including drawing on a canvas and making predictions.

  7. Integrate TensorFlow library

    • Learn to setup Neural networks with TensorFlow

    • Use Tensorflow to recognize numbers from 0-9

Course Features:

  • Step-by-step coding tutorials with detailed explanations.

  • Hands-on projects to solidify your understanding.

  • Graphical visualization of neural network decision boundaries.

  • Techniques to save and export trained models for real-world applications.

  • Comprehensive coverage from basic perceptrons to multi-layer perceptrons.

    That's a pretty good course that I can recommend. Neural networks are explained very good. It's good to have some experience with JS and React, because those are used but not explained that much.
