Runway ML makes machine learning easier to use for creators

Machine learning can feel like a foreign concept only useful to those with access to big machines. Runway ML aims to make machine learning easier to use for a wider audience, specifically for creators. It provides a click-and-drag interface that lets you link algorithms, import datasets, and most importantly, experiment. Looks like fun. Give it a go. Tags: machine learning

Kepler.gl, an open source tool for mapping large-scale data

Kepler.gl, a collaboration between Uber and Mapbox, allows for easier mapping of large-scale data. From Shan He for Uber: Showing geospatial data in a single web interface, kepler.gl helps users quickly validate ideas and glean insights from these visualizations. Using kepler.gl, a user can drag and drop a CSV or GeoJSON file into the browser, visualize it with different map layers, explore it by filtering and aggregating it, and eventually...

Outlier detection in R

Speaking of outliers, it’s not always obvious when and why a data point is an outlier. The Overview of Outliers package in R by Antony Unwin lets you compare methods. Articles on outlier methods use a mixture of theory and practice. Theory is all very well, but outliers are outliers because they don’t follow theory. Practice involves testing methods on data, sometimes with data simulated based on theory, better with...

Microsoft Excel painter

Remember the artist Tatsuo Horiuchi who uses Microsoft Excel to paint scenery? Four years later, he’s still at it. Watch below. Horiuchi is my favorite example of someone who shows that the tool is secondary to what you want to make. Spend less time debating about what software you should use to visualize your data, and spend more time deciding what you want to show. Tags: Excel, paintings, tools

Choosing the right metric reveals the story behind the subway mess in NYC

I forgot who sent this chart to me - it may have been a Twitter follower. The person complained that the following chart exaggerated how much trouble the New York mass transit system (MTA) has been facing in 2017, because of the choice of the vertical axis limits. This chart is vintage Excel, using Excel defaults. I find this style ugly and uninviting. But the chart does contain some good...

PowerPoint history lesson

David C. Brock writing for IEEE Spectrum delves into the origins of PowerPoint. PowerPoint is so ingrained in modern life that the notion of it having a history at all may seem odd. But it does have a very definite lifetime as a commercial product that came onto the scene 30 years ago, in 1987. Remarkably, the founders of the Silicon Valley firm that created PowerPoint did not set out...

Excel is the graveyard of charts, no!

It's true that Excel is responsible for large numbers of horrible charts. I just came across a typical example recently: This figure comes from Edward Wolff's 2012 paper, "The Asset Price Meltdown and the Wealth of the Middle Class." It's got all the hallmarks of Excel defaults. It's not a pleasing object to look at. However, it's also true that Excel can be used to make nice charts. Here is...

Semiotic, a visualization framework

Elijah Meeks released Semiotic into the wild. It’s a framework that allows quick charts but provides flexibility for custom stuff. Semiotic is a React-based data visualization framework. You can see interactive documentation and examples here. It satisfies the need for reusable data visualization, without committing to a static set of charting types. It came out of a need for a data visualization framework that let us make simple charts quickly...
