Today's blog post is a hands-on demo and evaluation of the Google Cloud Natural Language API. Like all cherry picked examples/demos, their site shows an impressive result in the system's ability to do entity identification, sentiment analysis, and extract syntax. How will the results be on a real world data... View More >

Backing Up a Podcast

by Kyle Polich

Everything on the internet is there forever. Right? It depends on what you mean. If something makes it into the Internet Archive, I feel pretty confident it will be around for the duration of my lifetime. Yet, I'm from a time right on the cusp on when permenance became a possibility. I can name many bands that were just a few years to early to appear on Youtube and get an album into iTunes. Those works are much more at risk of bit... View More >

The frightening, futurist portrayals of artificial intelligence and anthropomorphic robots portended in Hollywood films and sci-fi novels are fictional. In reality, AI is already changing our everyday lives, almost entirely in ways that benefit our society. Apple's Siri, voice recognition, Google's ability to recognize photos and videos of cats, weather forecasts, and email spam filtering, are all examples. Indeed, we've witnessed quantum leaps in the quantity and quality of a wide range of common technologi... View More >

Machine learning has been an essential tool for solving computer vision tasks such as image classification, object detection, instance recognition, and semantic segmentation, among others. The crux of machine learning approaches involves data. Training a machine requires enormous amounts of usable data. Why? Suppose you want to learn about monkeys and apes. Let's also assume you've never seen any monkeys or apes in your lifetime, until one day, someone shows you a picture of a monkey and an ape. It might be difficult to generalize from one picture and discern the differences between a monkey and an ape. If you saw perhaps 50 pictures of each species, you would have a greater chance of noticing that monkeys tend to be smaller than apes and that monkeys tend to have tails, whereas apes do not. Now if you saw thousands of pictures of both monkeys and apes, it might become very clear to you that the two are in fact, very different. For example, you might discover monkeys and apes have different nose structures, upper bodies, feet and so... View More >

I find that the broad media discussion of machine learning models, algorithmic decision making, and artificial intelligence is written by some very ill informed commentators on the subject. I do believe this is an important topic. We covered some of these ideas in episodes like Auditing Algorithms with Christian Sandvig and Predictive Policing with Kristian Lum. It's a central theme in the widely discussed Weapons of Math Destruction by Cathy O'Neil<... View More >

In a letter to Nature published in 1907, Francis Galton described an event that had taken place at a county fair, where he asked roughly 800 people to guess the weight of an ox. The average estimate was 1,197 pounds. The actual weight was 1,198, which meant that the average guess was a near-perfect estimate. Many people who participated from the crowd were considered experts, such as farmers and butchers, but many people were non-experts who were just attending the fair. Also, none of them guessed the correct weight, and only one person guessed 1,197. The next closest guess was 1,199, which was given by two participant... View More >
