Introduction to Math for Data Science

Abstract: 

With the availability of data, there is a growing demand for talent who can analyze and make sense of it. This makes practical math all the more important because it helps infer insights from data. However, mathematics comprises many topics, and it is hard to identify which ones are applicable and relevant for a data science career. Knowing these essential math topics is key to integrating knowledge across data science, statistics, and machine learning. It has become even more important with the prevalance of libraries like PyTorch and scikit-learn, which can create """"black box"""" approaches where data science professionals use these libraries but do not fully understand how they work.

In this training, Thomas Nield (author of O'Reilly book """"Essential Math for Data Science"""") will provide a crash-course of carefully curated topics to jumpstart proficiency in key areas of mathematics. This includes probability, statistics, hypothesis testing, and linear algebra. Along the way you’ll integrate what you’ve learned and see practical applications for real-world problems. These examples include how statistical concepts apply to machine learning, and how linear algebra is used to fit a linear regression. We will also use Python to explore ideas in calculus and model-fitting, using a combination of libraries and from-scratch approaches.

Session Outline:

Lesson 1: Calculus and Probability Basics

Become acquainted with fundamental calculus concepts like derivatives and integrals, and how to calculate them from scratch in Python as well as using the SymPy library. Afterwards, we will use this knowledge to build a normal distribution and interpret its PDF, CDF, and PPF.

Lesson 2: Statistics and Hypothesis Testing

After gaining knowledge on probability and calculus, this section will turn to ideas on hypothesis testing and understanding the relationship between a sample and population. We will also get context on how samples and populations play a role in data collection, and hypothesis testing's role in machine learning.

Lesson 3: Linear Algebra and Basic Machine Learning

We finally turn our attention to some basic linear algebra concepts, like linear transformations, and how they play a role in machine learning. We will use the most basic machine learning model, the linear regression, to learn about matrix decomposition and gradient descent, and why it extends into more advanced topics like neural networks and deep learning.

After this session, attendees will understand a variety of from scratch and library approaches to explore mathematical concepts in data science. They will be able to perform derivatives and integrals using SymPy, and use probability distributions and hypothesis testing using SciPy. Most importantly, they will integrate probability, statistics, and linear algebra concepts and understand their relevance to model fitting and machine learning.
