(Extended Abstract).
Abstract: Currently, most systems for human-robot teaching allow only one mode of teacher-student interaction (e.g., teaching by demonstration or feedback), and teaching episodes have to be carefully set-up by an expert. To understand how we might integrate multiple, interleaved forms of human instruction into a robot learner, we performed a behavioral study in which 44 untrained humans were allowed to freely mix interaction modes to teach a simulated robot (secretly controlled by a human) a complex task. Analysis of transcripts showed that human teachers often give instructions that require considerable interpretation and are not easily translated into a form useable by machine learning algorithms. In particular, humans often use implicit instructions, fail to clearly indicate the boundaries of procedures, and tightly interleave testing, feedback, and new instruction. In this paper, we detail these teaching patterns and discuss the challenges they pose to automatic teaching interpretation as well as the machine-learning algorithms that must ultimately process these instructions. We highlight the challenges by demonstrating the difficulties of an initial automatic teacher interpretation system.

| Aug 24 2010: | Alon Efrat, UA Associate Professor of Computer Science, is working with a team of researchers on a project intended to help prevent a telecommunications meltdown in the event of an attack or natural disaster.
A nuclear weapon launched over the U.S. could create an electromagnetic pulse that would knock out access to power and electronics. To prepare for this and other potential disasters, Alon Efrat and his colleagues are working on a newly funded research project fueled by the philosophy that telecommunications providers should be aware of system weaknesses and actively work to secure them.

| Jul 29 2010: | The department is pleased to announce that Paul Cohen, Ian Fasel, Kobus Barnard and Deva Ramanan (UC Irvine) have received a $5M, five year award from DARPA's Mind's Eye program. Clay Morrison assisted with preparing the proposal. Please join us in congratulating them!
The goal of Mind's Eye is to build a camera that can tell us what it sees. DARPA is interested in this problem because the cost of surveillance teams is very high, as is the cost of monitoring "dumb" remote cameras. A "smart" camera ought to be able to report suspicious activity. Mind's Eye is a particularly interesting problem because it merges computer vision with machine learning and models of human activities. The approach of the UA-UCI team involves three levels of inference: At the highest level, there are models of activity and at the lowest, there are vision algorithms optimized for pose recognition and tracking. The innovation is at the middle level, where simulation will generate possible futures a brief instant before they happen in the physical world. Said differently, the approach is to imagine, via simulation, what might be happening in the scene. Imagination can constrain conventional vision processing and should make it more accurate and efficient. Learn more | |
| Jul 12 2010: | Alon Efrat, along with Gil Zussman of Columbia and Eytan Modiao of MIT, has been awarded $545,000 jointly by NSF to identify the most vulnerable parts of a telecommunications network and to provide a-priori protection plan and dynamtic restoration algorithms. Abstract: Telecommunication networks heavily rely on physical infrastructures (such as optical fibers, amplifiers, routers, and switches), and therefore, are vulnerable to natural disasters, such as earthquakes or floods, as well as to physical attacks, such as an Electromagnetic Pulse (EMP) attack. Physical attacks or disasters affect a specific geographical area or areas, and will result in failures of a large number of neighboring components. The goals of the project are to develop techniques to identify the most vulnerable parts of the network, and to develop tools to provide a-priori protection plan for the network, and develop dynamic restoration algorithms that will improve the resilience of networks to geographically correlated attacks and prevent cascading failures. | |

They applied individually to this very competitive program: a few thousand students apply, yet only 300 students are chosen (it was 400 last year, including Charles Magahern). A ticket to attend the event costs $1599 per developer. The WWDC Student Scholarship offers qualified university students the opportunity to receive a free ticket to attend the Apple Worldwide Developers Conference 2010. Charles, Cody, and Tom collaborated on an iPhone application call Twitscape. James created the application's icon. It is a location-based, anonymous Twitter client. People without a Twitter account can use the application to keep up with what people around them are Tweeting. This application is available at Apple's App Store. All four are extremely interested in Apple's products, ranging from MacBooks to iPhone/iPad. They feel that Apple creates truly amazing software for their products. They believe that they were selected because of their experience in iPhone and Mac development, their passion for software development, and their professional work experience. About WWDC Over 5,000 of the world’s best and brightest Apple developers come together for the week-long Apple Worldwide Developers Conference at Moscone West, in San Francisco, California.

| May 06 2010: | The integration of computer science into the K-12 curriculum in the U.S. has not kept pace with other countries, and a serious shortage of information technologists exists at all levels, according to a new study by computer science professionals including the University of Arizona's Suzanne Westbrook. The overall shortage of women and underrepresented minority students in computing and the increasing need for professionals in the field motivated Westbook and leaders from the Computer Science Teachers Association, or CSTA, the Anita Borg Institute for Women and Technology, or ABI, to investigate barriers to the profession and make recommendations for improvement. Westbook, associate head of the UA department of computer science, studies gender issues in computing education, and she is a member of the Education, Outreach and Training team of the National Science Foundation funded iPlant Collaborative project.

| Apr 21 2010: | CLIME: Concept Learning from Intrinsically Motivated sensory-motor Experience, award from DARPA Most current robots are designed for solving one or a handful of specific, sophisticated tasks, using carefully designed sensor systems (such as computer vision systems) for localizing objects, terrain and landmarks. However these robots do not truly understand anything about these objects, such as how they can be acted upon, how they interact with each other, or any causal relationships between their visual and physical properties. Moreover, the only way for robots to learn new concepts is for a human to provide very labor-intensive hand coding, sometimes utilizing supervised machine learning. Thanks to a $250,000 award from DARPA to Asst. Research Professor Ian Fasel, CLIME (Concept Learning from Intrinsically Motivated sensory-motor Experience) is a new project which seeks to establish if it is possible for a robot to learn language-like conceptual representations through unsupervised sensory-motor experience with the world. Robots in this project will be "born" with primitive sensory motor skills, but will bootstrap to higher level concepts by "playing" with objects, driven by an internal, information-theoretic "curiosity", and using their experiences to build rich, multi-modal representations of those objects and features about them such as affordances and common causes. Ultimately, these robots may one day be able to truly understand human speech by connecting "words" to all the implications those words have about the physical world. Learn more | |
| Apr 21 2010: | The Arizona Articulatory, Acoustic, and Visual Speech Database, award from AHSS The most defining characteristic of humans is our facile ability to learn and use language. Yet every domain of language is itself a complex system. Sound is the most concrete of these, with measurable acoustic and articulatory properties, yet it is only marginally understood, in part because of its inherent complexity and in part because of challenges in collecting and analyzing data, particularly articulatory data. Recently, Professors Diana Archangeli, Linguistics, and Ian Fasel, CS, received an $29,994 AHHS (Arts, Humanities & Social Sciences Grants for Faculty) award to develop new methods for understanding the non-acoustic aspects of speech. In this research, ultrasound, video, audio, nasal airflow, and electroglottography are simultaneously captured during speech, and then sophisticated machine learning methods are used to analyze the microstructure of vocal tract gestures, tongue positions, lip movement, audio, and their inter-relationships. One of the near-term outcomes of this project will be the creation of the public "Arizona Articulatory, Acoustic, and Visual Speech Database", which will serve as a foundation for a wide variety of research topics ranging from phonology, automatic speech recognition, speech therapy, music and language teaching, and documentation of Native American languages.

| Apr 05 2010: | A long-missing part of the educational informatics focal problem has been social networking and large-scale educational gaming for students. Thanks to a $1.4M, three-year award from DARPA's CS STEM program to Paul Cohen and Carole Beal, this piece will soon be developed. The project is called "Teach Ourselves," and is based on Beal's work showing that students not only enjoy authoring math problems but learn math by doing so. Social networks such as Teach Ourselves (which will be built on top of Facebook) provide large audiences for student-authored problems. Students will get points for both authoring and solving problems, and they will be able to exchange points for real goods. A marketplace will be developed not only for math problems but for all sorts of intellectual work, including writing, translation, tutoring, and so on. Students will self-organize into guilds around these kinds of activities. |
