SVMs are a popular classification technique used in data science and machine learning.
In this video, I walk through how support vector machines work in a visual way, and then go step by step through how to write a Python script to use SVMs to classify muffin and cupcake recipes.
In Part 1a, I visually define the following terms:
Margin
Support vectors
Hyperplane
In Part 1b, I go through the following steps in a Jupyter Notebook:
Import libraries (pandas, numpy, sklearn, matplotlib)
Import data
Prepare the data
Fit the model
Visualize results
Predict a new case
In Part 2, I talk about ways to tune the model:
Higher dimensions
Multiple classes
C parameter
Kernel trick (RBF with gamma)
In Part 3, I talk about the pros and cons of SVM.
