Supervised Learning

This repository will hold the supervised learning content that I teach at Europeia University on a course about Big Data and Data Analytics.

The program (in Portuguese) can be found here.

The notebooks on this repository are separated into theory and practice.

Theory

1. Data Collection
   • 1.1. Data Sources
   • 1.2. Data Collection Considerations
2. Data Exploration and Preparation
   • 2.1. Data Exploration
   • 2.2. Data Preparation/Cleaning
3. Split Data into Training and Test Sets
   • 3.1. Holdout Method
   • 3.2. Cross Validation
   • 3.3. Data Leakage
   • 3.4. Best Practices
4. Choose a Supervised Learning Algorithm
   • 4.1. Consider algorithm categories
   • 4.2. Evaluate algorithm characteristics
   • 4.3. Try multiple algorithms
5. Train the Model
   • 5.1. Objective Function (Loss/Cost Function)
   • 5.2. Optimization Algorithms
   • 5.3. Overfitting and Underfitting
6. Evaluate Model Performance
   • 6.1. Performance Metrics for Regression Models
   • 6.2. Performance Metrics for Classification Models
7. Model Tuning and Selection
   • 7.1. Hyperparameter Tuning
   • 7.2. Ensemble Methods

Practice

Clicking on the links below will open the notebooks in Colab and allow you to run it on the cloud.

• Regression Example

• Classification examples:

  • kNN
  • Random Forest
  • SVM

Get Started

Ensure that you have install conda.

1. Create a new environment

conda create -n ml

2. Activate the new environment

conda activate ml

3. Install poetry with conda

conda install poetry

4. Install all packages

poetry install
