Predicting the Risk and Trajectory of Intensive Care Patients Using Survival Models
(2006-08-30)
Using artificial intelligence to assist physicians in patient care has received sustained interest over the past several decades. Recently, with automated systems at most bedsides, the amount of patient information collected ...
Javari: Adding Reference Immutability to Java
(2006-09-05)
This paper describes a programming language, Javari, that is capable of expressing and enforcing immutability constraints. The specific constraint expressed is that the abstract state of the object to which an immutable ...
Resilient Network Coding In the Presence of Byzantine Adversaries
(2006-08-05)
Network coding substantially increases network throughput. But since it involves mixing of information inside the network, a single corrupted packet generated by a malicious node can end up contaminating all the information ...
Human Document Classification Using Bags of Words
(2006-08-09)
Humans are remarkably adept at classifying text documents into cate-gories. For instance, while reading a news story, we are rapidly able to assess whether it belongs to the domain of finance, politics or sports. Automating ...
Finding the needles in the haystack: Generating legal test inputs for object-oriented programs
(2006-08-31)
A test input for an object-oriented program typically consists of asequence of method calls that use the API defined by the programunder test. Generating legal test inputs can be challenging because,for some programs, the ...
Task-Structured Probabilistic I/O Automata
(2006-09-05)
Modeling frameworks such as Probabilistic I/O Automata (PIOA) andMarkov Decision Processes permit both probabilistic andnondeterministic choices. In order to use such frameworks to express claims about probabilities of ...
Random Lens Imaging
(2006-09-02)
We call a random lens one for which the function relating the input light ray to the output sensor location is pseudo-random. Imaging systems with random lensescan expand the space of possible camera designs, allowing new ...
Sensitive Manipulation
(2007-03-02)
This thesis presents an effective alternative to the traditionalapproach to robotic manipulation. In our approach, manipulation ismainly guided by tactile feedback as opposed to vision. Themotivation comes from the fact ...
Phonetic Classification Using Hierarchical, Feed-forward, Spectro-temporal Patch-based Architectures
(2007-02-01)
A preliminary set of experiments are described in which a biologically-inspired computer vision system (Serre, Wolf et al. 2005; Serre 2006; Serre, Oliva et al. 2006; Serre, Wolf et al. 2006) designed for visual object ...
PPR: Partial Packet Recovery for Wireless Networks
(2007-02-02)
Bit errors occur over wireless channels when the signal isn't strongenough to overcome the effects of interference and noise. Currentwireless protocols may use forward error correction (FEC) to correct forsome (small) ...
