Welcome to the Neural Networks Research Group web site.

The group is directed by Prof. Risto Miikkulainen and is located at the Department of Computer Sciences at the University of Texas at Austin.


GECCO Awards

Elliot Meyerson (NNRG PhD 2018) and Risto Miikkulainen received two awards at the Genetic and Evolutionary Computation Conference (GECCO): First, a Best-Paper award in Genetic Algorithms for Simple Genetic Operators are Universal Approximators of Probability Distributions (and other Advantages of Expressive Encodings) (together with Xin Qiu). This paper shows empirically and theoretically that solution representations can be as important as search operators in improving performance. Second, they won a Silver Award in the Human Competitive Results Competition for Evaluating Medical Aesthetics Treatments through Evolved Age-Estimation Models (together with Xin Qiu, Ujjayant Sinha, Raghav Kumar, Karen Hofmann, Matt Yan, Michael Ye, Jingyuan Yang, Damon Caiazza, and Stephanie Manson Brown). This paper improves the state-of-the art in age estimation from face images (with about half the error of human estimation), but also shows that evolutionary metalearning methods can discover more accurate models than those designed by human data scientists.
