With any new skill, hobby, or career path, you likely have more questions than answers. How do I get started? What skills do I need to focus on first? What sources do I trust to learn all of this? Data science and machine learning are no different. While each field under the umbrella of data science has its own unique set of skills, there are a few basics that are universal. Here are the five skills you need to get started with data science and machine learning.
1. Linear Algebra
Time to bust out the high school and college textbooks again, because you’ll be needing algebra if you want to excel in data science. Linear algebra involves a lot of vectors and matrices, which are useful in representing large amounts of data – something you’ll see often in your life as a data scientist. Linear algebra is a core skill for deep learning, if you choose to go down that path.
2. Statistics & Probability
Statistics involves the collection, analysis, interpretation, presentation, and organization of data. Sound familiar? There are lots of similarities between statistics and data science, such as examining probability, bayesian thinking, experimental design, regression, and so on.
Uh oh, more math. While you may not need to go back and relearn everything about calculus from when you were 16, you need to understand the core concepts at least. This includes knowing more about gradient descent, linear regression, limits & derivatives, and so on.
Computer science has been around for quite some time, with a lot of theories and practices making their way over to data science. Many computer scientists make career transitions into data science, so there are plenty of parallels between the two. Core knowledge includes data structures, trees & graphs, lists & dictionaries, and more important skills.
5. A Coding Language
This is where it gets a bit fuzzy since there are debates about what coding language is best for data science. The most common two are Python & R, each with their own strengths and weaknesses. Python is versatile and often used in computer science as well, while R is popular for data analysis. There are many libraries, frameworks, and platforms that use either R or Python, so knowing one language won’t limit you.
Bonus Skills on How to Start Machine Learning: Communication and Business Knowledge
It’s not all numbers, charts, and graphs. The best data scientists will also know soft, non-technical skills in addition to their coding and programming toolkit when learning how to start machine learning. You’ll likely be working with a variety of people, so it’s important to know how to communicate across departments – including verbal communication and data presentation – as well as knowing some basics of business to understand what a customer or client may want.
