Was the Patient Cured? Understanding Semantic Categories and Their Relationships in Patient Records
(2006-06-28)
In this thesis, we detail an approach to extracting key information in medical discharge summaries. Starting with a narrative patient report, we first identify and remove information that compromises privacy (de-identifi ...
MORE: A Network Coding Approach to Opportunistic Routing
(2006-06-30)
Opportunistic routing has the potential to substantially increase wireless network throughput. Prior work on opportunistic routing, however, requires tight node coordination. Different nodes in a network must have knowledge ...
Using Probabilistic I/O Automata to Analyze an Oblivious Transfer Protocol
(2006-06-19)
We demonstrate how to carry out cryptographic security analysis ofdistributed protocols within the Probabilistic I/O Automataframework of Lynch, Segala, and Vaandrager. This framework providestools for arguing rigorously ...
Iterative Collaborative Ranking of Customers and Providers
(2006-07-04)
This paper introduces a new application: predicting the Internet provider-customer market. We cast the problem in the collaborative filtering framework, where we use current and past customer-provider relationships to ...
Using Task-Structured Probabilistic I/O Automata to Analyze an Oblivious Transfer Protocol
(2006-06-20)
The Probabilistic I/O Automata framework of Lynch, Segala and Vaandrager provides tools for precisely specifying protocols and reasoning about theircorrectness using multiple levels of abstraction, based on implementation ...
Approximate Correspondences in High Dimensions
(2006-06-15)
Pyramid intersection is an efficient method for computing an approximate partial matching between two sets of feature vectors. We introduce a novel pyramid embedding based on a hierarchy of non-uniformly shaped bins that ...
A Unified Information Theoretic Framework for Pair- and Group-wise Registration of Medical Images
(2006-01-25)
The field of medical image analysis has been rapidly growing for the past two decades. Besides a significant growth in computational power, scanner performance, and storage facilities, this acceleration is partially due ...
A Consistency Management Layer for Inter-Domain Routing
(2006-01-27)
This paper proposes an isolation layer -- a shim -- betweeninter-domain routing and packet forwarding. The job of this layer isto coordinate between Autonomous Systems (AS's) on when and how tomodify the forwarding state ...
Wide-Area Egomotion Estimation from Known 3D Structure
(2006-01-09)
We describe an algorithm that takes as inputs a coarse3D model of an environment, and a video sequence acquiredwithin the environment, and produces as output an estimateof the camera s 6-DOF egomotion expressed in the ...
Nuggeteer: Automatic Nugget-Based Evaluation Using Descriptions and Judgements
(2006-01-09)
TREC Definition and Relationship questions are evaluated on thebasis of information nuggets that may be contained in systemresponses. Human evaluators provide informal descriptions of eachnugget, and judgements (assignments ...
