Trading Structure for Randomness in Wireless Opportunistic Routing
(2007-02-23)Opportunistic routing is a recent technique that achieves high throughput in the face of lossy wireless links. The current opportunistic routing protocol, ExOR, ties the MAC with routing, imposing a strict schedule on ...

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 ...

A Trainable Object Detection System: Car Detection in Static Images
(1999-10-13)This paper describes a general, trainable architecture for object detection that has previously been applied to face and peoplesdetection with a new application to car detection in static images. Our technique is a ...

A Trainable System for Object Detection in Images and Video Sequences
(2000-05-01)This thesis presents a general, trainable system for object detection in static images and video sequences. The core system finds a certain class of objects in static images of completely unconstrained, cluttered scenes ...

Trajectory Analysis and Semantic Region Modeling Using A Nonparametric Bayesian Model
(2008-06-24)We propose a novel nonparametric Bayesian model, Dual Hierarchical Dirichlet Processes (Dual-HDP), for trajectory analysis and semantic region modeling in surveillance settings, in an unsupervised way. In our approach, ...

Trajectory and Force Control of a Direct Drive Arm
(1986-09-01)Using the MIT Serial Link Direct Drive Arm as the main experimental device, various issues in trajectory and force control of manipulators were studied in this thesis. Since accurate modeling is important for any ...

Trajectory Mapping ("TM''): A New Non-Metric Scaling Technique
(1993-12-01)Trajectory Mapping "TM'' is a new scaling technique designed to recover the parameterizations, axes, and paths used to traverse a feature space. Unlike Multidimensional Scaling (MDS), there is no assumption that the ...

Trans-membrane Signal Transduction and Biochemical Turing Pattern Formation
(1999-09-28)The Turing mechanism for the production of a broken spatial symmetry in an initially homogeneous system of reacting and diffusing substances has attracted much interest as a potential model for certain aspects of ...
-
Transcendence, Facticity, and Modes of Non-Being
(MIT Artificial Intelligence Laboratory, 1986-03)Research in artificial intelligence has yet to satisfactorily address the primordial fissure between human consciousness and the material order. How is this split reconciled in terms of human reality? By what duality is ...

Transductive Ranking on Graphs
(2008-08-07)In ranking, one is given examples of order relationships among objects, and the goal is to learn from these examples a real-valued ranking function that induces a ranking or ordering over the object space. We consider the ...

Transfer learning for image classification with sparse prototype representations
(2008-03-03)To learn a new visual category from few examples, prior knowledge from unlabeled data as well as previous related categories may be useful. We develop a new method for transfer learning which exploits available unlabeled ...

Transfering Nonlinear Representations using Gaussian Processes with a Shared Latent Space
(2007-11-06)When a series of problems are related, representations derived fromlearning earlier tasks may be useful in solving later problems. Inthis paper we propose a novel approach to transfer learning withlow-dimensional, non-linear ...

Transition Space
(1990-11-01)Informal causal descriptions of physical systems abound in sources such as encyclopedias, reports and user's manuals. Yet these descriptions remain largely opaque to computer processing. This paper proposes a ...

Translation Invariance in Object Recognition, and Its Relation to Other Visual Transformations
(1997-06-01)Human object recognition is generally considered to tolerate changes of the stimulus position in the visual field. A number of recent studies, however, have cast doubt on the completeness of translation invariance. In a ...

Translucent Procedures, Abstraction without Opacity
(1993-10-01)This report introduces TRANSLUCENT PROCEDURES as a new mechanism for implementing behavioral abstractions. Like an ordinary procedure, a translucent procedure can be invoked, and thus provides an obvious way to capture ...

Transparent Accountable Data Mining: New Strategies for Privacy Protection
(2006-01-27)Attempts to address issues of personal privacy in a world of computerized databases and information networks -- from security technology to data protection regulation to Fourth Amendment law jurisprudence -- typically ...

A Tree-Based Context Model for Object Recognition
(2010-10-29)There has been a growing interest in exploiting contextual information in addition to local features to detect and localize multiple object categories in an image. A context model can rule out some unlikely combinations ...

Triangulation by Continuous Embedding
(1997-03-01)When triangulating a belief network we aim to obtain a junction tree of minimum state space. Searching for the optimal triangulation can be cast as a search over all the permutations of the network's vaeriables. Our ...
