Level Up: Linear Regression in Python – Part 6

In the sixth lesson of the series we’ll discuss some methods for data transformation to improve a linear regression model. In the process, we’ll learn to simulate data with known properties, review some of the assumptions of linear regression, and continue to practice our Python skills. Here are some Stack Overflow questions related to the…

Unpacking the user research behind Collectives™

We spent over a hundred hours in 1-on-1 interviews and collected thousands of survey responses to better understand what our community and customers wanted to see in this product. This feedback shaped everything from naming to moderation, and helped us evolve and iterate the concept into what it is today.

Level Up: Linear Regression in Python – Part 5

In the fifth lesson of the series we’ll learn how to build more flexible linear models by adding interaction and polynomial terms. We’ll fit and inspect our models both mathematically and visually to understand how they work. In the process, we’ll continue to practice our Python skills and discuss some of the merits (and drawbacks)…

Let’s enhance: use Intel AI to increase image resolution in this demo

Across alien epics and procedural crime dramas, detectives and truth seekers have repeated the mantra: zoom and enhance. It’s passed into popular culture as a much-beloved meme, but in recent years, machine learning has increasingly made this fiction trope into an accessible reality. And we've got the demo to prove it.

Level Up: Linear Regression in Python – Part 4

In the fourth lesson of the series, we’ll talk about the matrix representation of the linear regression problem. In the process, we’ll discuss the basics of matrix multiplication. We’ll also see how this mathematical understanding can prepare us to make sense of error messages that we might encounter when fitting a model in Python. Here…

Level Up: Linear Regression in Python – Part 3

In the third lesson of the series, we’ll implement our first linear regression model with multiple predictors (this is called “multiple linear regression”). As an example, we’ll use a simulated dataset to predict student quiz scores. In the process, we’ll again practice our graphing and Python skills. Here are some Stack Overflow questions related to…
