Tragedy of the routing table: An analysis of collective action amongst Internet network operators
(2011-08-06)
This thesis analyzes and discusses the effectiveness of social efforts to achieve collective action amongst Internet network operators in order to manage the growth of the Internet routing table. The size and rate of growth ...
Learning and disrupting invariance in visual recognition
(2011-09-10)
Learning by temporal association rules such as Foldiak's trace rule is an attractive hypothesis that explains the development of invariance in visual recognition. Consistent with these rules, several recent experiments ...
Nonparametric Sparsity and Regularization
(2011-09-26)
In this work we are interested in the problems of supervised learning and variable selection when the input-output dependence is described by a nonlinear function depending on a few variables. Our goal is to consider a ...
Automatic Input Rectification
(MIT CSAIL, 2011-10-03)
We present a novel technique, automatic input rectification, and a prototype implementation called SOAP. SOAP learns a set of constraints characterizing typical inputs that an application is highly likely to process ...
Multi-Class Learning: Simplex Coding And Relaxation Error
(2011-09-27)
We study multi-category classification in the framework of computational learning theory. We show how a relaxation approach, which is commonly used in binary classification, can be generalized to the multi-class setting. ...
Vote the OS off your Core
(2011-07-27)
Recent trends in OS research have shown evidence that there are performance benefits to running OS services on different cores than the user applications that rely on them. We quantitatively evaluate this claim in terms ...
Faces as a "Model Category" for Visual Object Recognition
(2013-03-18)
Visual recognition is an important ability that is central to many everyday tasks such as reading, navigation and social interaction, and is therefore actively studied in neuroscience, cognitive psychology and artificial ...
Asynchronous Failure Detectors
(2013-01-30)
Failure detectors -- oracles that provide information about process crashes -- are an important abstraction for crash tolerance in distributed systems. The generality of failure-detector theory, while providing great ...
5D Covariance Tracing for Efficient Defocus and Motion Blur
(2012-11-16)
The rendering of effects such as motion blur and depth-of-field requires costly 5D integrals. We dramatically accelerate their computation through adaptive sampling and reconstruction based on the prediction of the anisotropy ...
Monitoring the Execution of Temporal Plans for Robotic Systems
(2012-10-04)
To achieve robustness in dynamic and uncertain environments, robotic systems must monitor the progress of their plans during execution. This thesis develops a plan executive called Pike that is capable of executing and ...
