Evolution of active categorical image classification via saccadic eye movement

I put together a couple demo videos for our Active Categorical Classifier (ACC) project that we’ll be presenting at the PPSN 2016 conference. If you’re interested in this project and can’t wait for PPSN, we have: a preprint of the

TPOT: A Python tool for automating data science

Machine learning is often touted as: A field of study that gives computers the ability to learn without being explicitly programmed. Despite this common claim, anyone who has worked in the field knows that designing effective machine learning systems is

Introducing TPOT, the Data Science Assistant

Some of you might have been wondering what the heck I’ve been up to for the past few months. I haven’t been posting much on my blog lately, and I haven’t been working on important problems like solving Where’s Waldo?

The reddit world map

We can all agree that online social networks dominate most people’s day-to-day Internet lives. 90% of all U.S. adults aged 18-29 have a Facebook account, and a large portion of those people check their Facebook at least once a day.

Visualizing evolution in action: Dynamic fitness landscapes

Fitness landscapes were invented by Sewall Wright in 1932. They map fitness, or reproductive success, of individual organisms as a function of genotype or phenotype. Organisms with higher fitness have a higher chance of reproducing, and populations therefore tend to

Visualizing evolution in action: Density-dependence and sympatric speciation

Fitness landscapes were invented by Sewall Wright in 1932. They map fitness, or reproductive success, of individual organisms as a function of genotype or phenotype. Organisms with higher fitness have a higher chance of reproducing, and populations therefore tend to

Visualizing evolution in action: Survival of the flattest

Fitness landscapes were invented by Sewall Wright in 1932. They map fitness, or reproductive success, of individual organisms as a function of genotype or phenotype. Organisms with higher fitness have a higher chance of reproducing, and populations therefore tend to

Evolving ecosystems can change more than previously thought

For decades, whenever ecology researchers used computer models to study how ecosystems change over time, they often assumed that the species in any given ecosystem are more-or-less fixed. The abundances of each species may change over time — and some

Evolution isn’t over until you click stop

Don't give up; you could be right on the edge of a really interesting discovery.

Why we need to run simulations out longer in Evolutionary Computation and Digital Evolution research I thought I had this whole evolutionary computation thing down by now. After all, I’ve been evolving things inside the computer for 5 years. I’ve

A short guide to using statistics in Evolutionary Computation

Plot showing average fitness with a 95% confidence interval

A couple weeks ago, I attended the Genetic and Evolutionary Computation Conference (GECCO) for the first time. While I was perusing through the workshops and tutorials available in the first couple days of the conference, I noticed something peculiar: There
