EXPLORING DATA SCIENCE

Now that the machine learning community has recognized the need to take algorithmic bias seriously, it’s time to explore potential ways to mitigate it — including algorithmic solutions. In this article, former DeepMind Research Engineering intern Joyce Xu asks, “how, algorithmically, can we ensure that the models we build are not reflecting and magnifying human biases in data?” From adversarial de-biasing to distributionally robust optimization, Joyce dives into several key potential fixes. A great long read!

“Decision intelligence is the discipline of turning information into better actions at any scale.”

In this comprehensive 14-minute read, Cassie Kozyrkov, Head of Decision Intelligence at Google, invites us to learn more about her field of expertise. After introducing important terminology and concepts — from “what’s a decision” to “what’s the difference between making a calculation versus making a decision” — Cassie digs deeper into this fascinating topic and demonstrates how relevant it is for the work of all data scientists.

Distance measures are ubiquitous in data science and machine learning. Many algorithms rely on them, and “knowing when to use which distance measure can help you go from a poor classifier to an accurate model.” In this article, Maarten Grootendorst does a fantastic job explaining the most common ones. For each of the nine distance measures, Maarten describes how they work, offers several use cases, and discusses their potential drawbacks.

Hey everyone!

Since we frequently receive questions about how to contribute to TDS, I’ve gathered some thoughts that I hope will help those interested in getting started.

First and foremost, we have put a lot of effort into our Write for Towards Data Science article. If you haven’t looked at it yet, start there! Years ago, this article was just a two-minute read. Now it’s a ten-minute read and likely worth your time!

When I meet an author face-to-face, I often end up paraphrasing sections of the above article to answer their questions. If someone asks a question that we…


From “What is the most neglected advice for beginners?” to “What makes a great article?”

We launched Towards Data Science about three years ago, and we’re still truly astonished to see the engagement we get from so many of you. Today, we’re a team of four editors and twenty editorial associates, and since we’ve been receiving questions from you, we decided to do our best to start answering them. I hope you find these four replies useful!

1. What is the most neglected advice that you would give to beginners?

Take the time to find out if being a data scientist is really your dream job.

Studies show that most people feel disengaged at work. Data scientists are no exception. …


As I hear criticisms about how data science is unscientific, I would like to clarify what is science, and to show how data scientists can answers these common criticisms about their field.

What is science?

Science is a quest to reach good explanations about the world. As David Deutsch pointed out in his book, The Beginning of Infinity, a good explanation is clear, precise and hard to vary.

What is data science?

Data science is a new scientific field that thrives to extract meaning from data and improve understanding. It represents an evolution from other analytical areas such as statistics, data analysis, BI and so on.

Data science has emerged today thanks to the explosion of data provided by the internet, raising computing power with more advanced technologies, the development of computer science and machine learning algorithms.
