> **Note:** All of the datasets we use in the course are available in the `data/` folder.
| **Section** | **Resource** | **Description** |
|-----|-----|-----| 
| 00 | A 6 step framework for approaching machine learning projects | A guideline for different kinds of machine learning projects and how to break them down into smaller steps. |
| 01 | Introduction to NumPy | NumPy stands for Numerical Python. It's one of the most used Python libraries for numerical processing (which is what much of data science and machine learning is). | 
| 02 | Introduction to pandas | pandas is a Python library for manipulating and analysing data. You can imagine pandas as a programmatic form of an Excel spreadsheet. |
| 03 | Introduction to Matplotlib | Matplotlib helps to visualize data. You can create plots and graphs programmatically based on various data sources. |
| 04 | Introduction to Scikit-Learn | Scikit-Learn or sklearn is full of data processing techniques as well as pre-built machine learning algorithms for many different tasks. |
| 05 | Milestone Project 1: End-to-end Heart Disease Classification | Here we'll put together everything we've gone through in the previous sections to create a machine learning model that is capable of classifying if someone has heart disease or not based on their health characteristics. We'll start with a raw dataset and work through performing an exploratory data analysis (EDA) on it before trying out several different machine learning models to see which performs best. | 
| 06 | Milestone Project 2: End-to-end Bulldozer Price Prediction | In this project we'll work with an open-source dataset of bulldozer sales information. We'll use this data to build a machine learning model capable of predicting the sales price of a bulldozer based on several input parameters such as size and brand. Since this dataset isn't perfect, we'll work through several data preprocessing steps before building a model. And since we'll be working towards predicting a number (price of bulldozers), this pr
