In this presentation we will review some of the private-preserving mechanisms applied in participatory sensing applications. We will start with a definition of privacy for participatory sensing and the threats associated with uncontrolled disclosure of sensitive information. We will then consider typical countermeasures and discuss some interesting research directions.... Carnegie Mellon Qatar, room 1202 Read more... Processing and Automatic Translation of Arabic Wikipedia Tue, 04/01/2014 - 12:00
Research on Arabic Natural Language Processing has been mostly focused on limited topics and domains such as news stories. There are recent efforts to adapt Arabic NLP systems to texts related to new topics and domains such as social networks. I present some of our efforts at CMUQ on processing multi-topic text from Arabic Wikipedia. That includes our annotation and statistical modeling of Arabic named entity recognition and supersense tagging. Moreover, I present our efforts in enhancing English to Arabic automatic translation aimed at extending Arabic Wikipedia.... Carnegie Mellon Qatar, room 1202 Read more... Searching Large Scale Image Collections Mon, 03/24/2014 - 12:00
Searching quickly and accurately in a large collection of images has become an important problem with many applications. The ultimate goal is to make visual search possible: allow users to search using images in addition to typing text. The typical approach is to index all the images of interest in a database and allow users to question the system with query images. Objects of interest might include landmarks, books, DVDs, billboards, and commercial products. Such a database can reach billions of images, and therefore pose challenges in terms of memory and computational requirements and recognition performance....

The "Moneyball revolution" coincided with a shift in the way professional sporting organizations handle and utilize data in terms of decision making processes. Due to the demand for better sports analytics and the improvement in sensor technology, there has been a plethora of ball and player tracking information generated within professional sports for analytical purposes. However, due to the continuous nature of the data and the lack of associated high-level labels to describe it - this rich set of information has had very limited use especially in the analysis of a team's tactics and strategy....

Machine Translation (MT) has been championed as an effective technology for knowledge transfer from English to languages with less digital content. An example of such efforts is the automatic translation of English Wikipedia to languages with smaller collections, such as Arabic. However, MT quality is still far from ideal for many of the languages and text genres. While translating a document, many sentences are poorly translated which can provide an incorrect text, and confuse the reader. Moreover, some of these sentences are not as informative and could be summarized to make a more cohesive document.... Carnegie Mellon Qatar, Room 1202 Read more... Cloud-Hosted Databases: A Consumer Perspective Tue, 11/12/2013 - 12:00
Service Level Agreements (SLA) represent the contract which captures the agreed upon guarantees between a service provider and its customers. The specifications of existing service level agreements (SLA) for cloud services are not designed to flexibly handle even relatively straightforward performance and technical requirements of consumer applications. In this talk, we present an end-to-end framework for consumer-centric SLA management of cloud-hosted databases, CloudDb AutoAdmin.... Carnegie Mellon Qatar, Room 1213 Read more... Towards supporting the elderly age in place: Multimodal dialogue processing in the ROBOHELPER project Sun, 11/10/2013 - 13:00
The goal of the ROBOHELPER project is to design and develop robotic assistants that could help the elderly live independently. In the first phase of this project, we are focusing on the multimodal interface required for the human to communicate with the robot. I will first describe the data collection of human-human interactions we carried out with elderly subjects. I will then discuss two models: one for pronominal and deictic reference resolution, and one for dialogue act classification.... Carnegie Mellon Qatar, Room 1213 Read more... Descriptive Minicomplexity Mon, 11/04/2013 - 12:00
Minicomplexity is the computational complexity theory that we can build by analogy to standard Computational Complexity Theory, when our computational model and resource of interest are not the Turing machine and its running time, but instead the two-way finite automaton (2FA) and its size. Descriptive minicomplexity is the part of this theory where the computational power of 2FAs is characterized in terms of logical formulas.... Carnegie Mellon Qatar, Room 1202 Read more... Computer-Based Mathematics Tue, 10/29/2013 - 12:00
Conrad Wolfram from Wolfram Research will be speaking about Wolfram|Alpha, Mathematica, and Computer Based Mathematics.
Important note: This presentation will start promptly at 12:00 and conclude at 12:30. Please arrive a few minutes early.
Learning to control a robotic device is generally accomplished by forming a new cognitive map between the body motions and extrapersonal space. Here, I consider the challenge of remapping movement-to-space representations in survivors of spinal cord injury, for the control of powered robotic wheelchairs. The goal is to facilitate this remapping by developing interfaces between body motions and navigational commands that exploit the degrees of freedom that disabled individuals are most capable to coordinate. The main novelty of this approach lies in substituting the joystick of the wheelchair with a wearable shirt.... Carnegie Mellon Qatar, Room 1202 Read more...
