Knowledge Driven Recognition of the Human Body
(MIT Artificial Intelligence Laboratory, 1976-01)This paper shows how a good internal model of the subject viewed aids in the visual recognition and following of key parts. The role of knowledge driven top-down tools and methods is shown by recognizing a series of human ...

Mini-Robot Group User's Guide Part 2: Access From ITS
(MIT Artificial Intelligence Laboratory, 1978-06)Part 2 of the MINI-ROBOT USER'S GUIDE describes those devices attached to the mini-robot system which may be accessed from ITS, and describes the appropriate software for accessing them. Specifically, the photowriter, ...

Guided Time Warping for Motion Editing
(2007-08-01)Time warping allows users to modify timing without affecting poses. It has many applications in animation systems for motion editing, such as refining motions to meet new timing constraints or modifying the acting of ...

Style Translation for Human Motion
(2005-08-01)Style translation is the process of transforming an input motion into a new style while preserving its original content. This problem is motivated by the needs of interactive applications, which require rapid processing ...

Example-Based Control of Human Motion
(2004-07-01)In human motion control applications, the mapping between a control specification and an appropriate target motion often defies an explicit encoding. We present a method that allows such a mapping to be defined by example, ...

A Note on Perturbation Results for Learning Empirical Operators
(2008-08-19)A large number of learning algorithms, for example, spectral clustering, kernel Principal Components Analysis and many manifold methods are based on estimating eigenvalues and eigenfunctions of operators defined by a ...

A Stored Picture Hacking Facility
(MIT Artificial Intelligence Laboratory, 1972-06)A short description of LISP functions that have been written for use with the stored picture facility. These functions allow one to display an image of a stored scene on the 340 scope, and produce graphs and histograms of ...

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 ...

Adaptive Envelope MDPs for Relational Equivalence-based Planning
(2008-07-29)We describe a method to use structured representations of the environmentâ s dynamics to constrain and speed up the planning process. Given a problem domain described in a probabilistic logical description language, we ...
-
Cognitive Cliches
(MIT Artificial Intelligence Laboratory, 1986-04)This paper is an exploration of a wide class of mental structures called cognitive cliches that support intermediate methods that are moderately general purpose, in that a few of them will probably be applicable to any ...

Understanding camera trade-offs through a Bayesian analysis of light field projections - A revision
(2008-07-28)Computer vision has traditionally focused on extracting structure,such as depth, from images acquired using thin-lens or pinholeoptics. The development of computational imaging is broadening thisscope; a variety of ...

Event Order Abstraction for Parametric Real-Time System Verification
(2008-07-28)We present a new abstraction technique, event order abstraction (EOA), for parametric safety verification of real-time systems in which ``correct orderings of events'' needed for system correctness are maintained by timing ...

An $\Omega(n \log n)$ Lower Bound on the Cost of Mutual Exclusion
(2006-07-23)We prove an $\Omega(n \log n)$ lower bound on the number ofnon-busywaiting memory accesses by any deterministic algorithm solving$n$ process mutual exclusion that communicates via shared registers.The cost of the algorithm ...

Elastic-Net Regularization in Learning Theory
(2008-07-24)Within the framework of statistical learning theory we analyze in detail the so-called elastic-net regularization scheme proposed by Zou and Hastie ["Regularization and variable selection via the elastic net" J. R. Stat. ...
-
A Projected Subgradient Method for Scalable Multi-Task Learning
(2008-07-23)Recent approaches to multi-task learning have investigated the use of a variety of matrix norm regularization schemes for promoting feature sharing across tasks.In essence, these approaches aim at extending the l1 framework ...

Composable Probabilistic Inference with Blaise
(2008-07-23)Probabilistic inference provides a unified, systematic framework for specifying and solving these problems. Recent work has demonstrated the great value of probabilistic models defined over complex, structured domains. ...

A Distributed Building Evacuation System
(2008-07-14)This thesis investigates the feasibility of a smart building evacuation system, capable of guiding occupants along safe paths to exits and responding to changing threats. Inspired by developments in amorphous computing, ...
