Computer Science Research Seminar

Date: 2:10pm, Friday, October 3
Location: Engineering 3070

This week in the Computer Science Research Seminar we have two of our Ph.D. students reporting on their research.

Speaker: Joost Huizinga, Ph.D. student in Computer Science (advisor: Jeff Clune)
Title: Evolving neural networks that are both modular and regular
Abstract:
An open question in biology is why and how brains evolved their regular, modular and hierarchical structures. An open question in computer science is how to produce intelligent neural networks that have these same structural properties as natural brains.   One popular method for producing artificial neural networks is to evolve them, but such evolved networks rarely contain these properties.
 
In this talk I will describe my research into combining two recent techniques, one for evolving neural modularity and one for evolving neural regularity, to produce neural networks that are both modular and regular. I will show that this combined technique improves the performance (intelligence) of these networks, and I will discuss how this suggests an explanation as to why and how these structures evolved in nature. Lastly, I will briefly touch upon my most recent research, where I apply these techniques to the brains of simulated robots that have to gather food and avoid predators to survive.

Title: 3DTouch: A wearable 3D input device for 3D applications
Abstract:
3D applications appear in every corner of life in the current technology era. There is a need for an ubiquitous 3D input device that works with many different platforms, from head-mounted displays to mobile touch devices, 3DTVs, and even the Cave Automatic Virtual Environments. We present 3DTouch, a novel wearable 3D input device worn on the fingertip for 3D manipulation tasks.  3DTouch is designed to fill the missing gap of a 3D input device that is self-contained, mobile, and universally working across various 3D platforms. This paper presents a low-cost solution to designing and implementing such a device.
Our approach relies on a relative positioning technique using an optical laser sensor and a 9-DOF inertial measurement unit. The device employs touch input for the benefits of passive haptic feedback, and movement stability. On the other hand, with touch interaction, 3DTouch is conceptually less fatiguing to use over many hours than 3D spatial input devices. We propose a set of 3D interaction techniques including selection, translation, and rotation using 3DTouch. An evaluation also demonstrates the device’s tracking accuracy of 1.10 mm and 2.33 degrees for subtle touch interaction in 3D space. We envision that modular solutions like 3DTouch opens up a whole new design space for interaction techniques to further develop on. With 3DTouch, we attempt to bring 3D applications a step closer to users.

UW Researchers Publish on Creative Thinking in Robots

Jeff Clune and his students are not only getting robots to think, but to think creatively. “The long-term goal is to build robots as nimble as natural animals, like hawks and jaguars, and as smart as humans,” says Clune, a University of Wyoming associate professor in the Department of Computer Science. “

Students Create Computer Model to Determine Surface Shade and Measure Snowmelt in Colorado River Basin

December 12, 2013 — In an attempt to measure snowmelt in a mountainous region northwest of Boulder, Colo., two University of Wyoming students are determining surface shade through a computer model they’ve created. They hope their high-performance computing research eventually can be scaled up for use on Mount Moran, UW’s high-performance computing cluster, and be a useful tool for modeling solar radiation for the entire Upper Colorado River Basin.

Why are English majors studying computer science?

December 3, 2013 — Ten years ago, professors in computer science departments everywhere wondered how undergraduates from a broad range of fields could be attracted to computer science (CS). We were convinced that this material would be vital for their careers, but we were up against negative stereotypes of programmers, and the prediction that most software jobs were about to be outsourced to the third world.
