Organizing a Global Coordinate System from Local Information on an Amorphous Computer
(1999-08-29)
This paper demonstrates that it is possible to generate a reasonably accurate coordinate system on randomly distributed processors, using only local information and local communication. By coordinate systems we imply ...
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 ...
Amorphous Computing
(1999-08-29)
Amorphous computing is the development of organizational principles and programming languages for obtaining coherent behaviors from the cooperation of myriads of unreliable parts that are interconnected in unknown, ...
Co-dimension 2 Geodesic Active Contours for MRA Segmentation
(1999-08-11)
Automatic and semi-automatic magnetic resonance angiography (MRA)s segmentation techniques can potentially save radiologists larges amounts of time required for manual segmentation and cans facilitate further data analysis. ...
Boosting Image Database Retrieval
(1999-09-10)
We present an approach for image database retrieval using a very large number of highly-selective features and simple on-line learning. Our approach is predicated on the assumption that each image is generated by a ...
Multiple Scales in Small-World Networks
(1999-08-11)
Small-world architectures may be implicated in a range of phenomena from networks of neurons in the cerebral cortex to social networks and propogation of viruses. Small-world networks are interpolations of regular and ...
Interactive Supercomputing with MIT Matlab
(1998-07-28)
This paper describes MITMatlab, a system that enables users of supercomputers or networked PCs to work on large data sets within Matlab transparently. MITMatlab is based on the Parallel Problems Server (PPServer), a ...
A Comparative Analysis of Reinforcement Learning Methods
(1991-10-01)
This paper analyzes the suitability of reinforcement learning (RL) for both programming and adapting situated agents. We discuss two RL algorithms: Q-learning and the Bucket Brigade. We introduce a special case of the ...
A Control Algorithm for Chaotic Physical Systems
(1991-10-01)
Control algorithms which exploit the unique properties of chaos can vastly improve the design and performance of many practical and useful systems. The program Perfect Moment is built around such an algorithm. Given ...
Intellectual Property and Software: The Assumptions are Broken
(1991-11-01)
In March 1991 the World Intellectual Property Organization held an international symposium attended primarily by lawyers, to discuss the questions that artificial intelligence poses for intellectual property law (i.e., ...
