Image Recognition with Neural Networks From Scratch
What you'll learn
- Write a Python program that recognizes images from scratch without using any libraries!
- Understand A Neural Network is.
- Understand some important mathematical prerequisites such as functions and their computational graphs.
- Understand conceptually what a derivative and a gradient is to fully appreciate the Gradient Descent Algorithm.
- Understand the Gradient Descent Algorithm, the central algorithm in machine learning with Neural Networks.
- Understand Backpropagation and its importance in computing gradients.
- Be able to implement the full Python program in 50 lines of code that recognizes images.
Requirements
- Some basic knowledge of Python.(Supplemental "Crash Course" resources are provided to review/learn Python.)
- Some basics knowledge of Numpy.(Supplemental "Crash Course" resources to review/learn Numpy.)
- Some high school precalculus.
Description
This is an introduction to Neural Networks. The course explains the math behind Neural Networks in the context of image recognition. By the end of the course, we will have written a program in Python that recognizes images without using any autograd libraries. The only prerequisite is some high school precalculus. Although the prerequisite is minimal, we will discuss many advanced topics including:
1) functions and their computational graphs.
2) neural networks
3) conceptually understand the derivative and the gradient.
4) gradient descent and backpropagation
5) the multivariable chain rule
6) mini-batch gradient descent
Who this course is for:
- Beginner Developers who wish to understand Neural Networks.
- Any math enthusiast who wishes to understand how matrix multiplication and the exponential function are the only two functions needed to recognize images!
- Any student who wishes to see one of the most useful and powerful application of high school math!
