Advanced Programming Language Features for Executable Design Patterns "Better Patterns Through Reflection
(2002-03-22)
The Design Patterns book [GOF95] presents 24 time-tested patterns that consistently appear in well-designed software systems. Each pattern is presented with a description of the design problem the pattern addresses, as ...
On the Dirichlet Prior and Bayesian Regularization
(2002-09-01)
A common objective in learning a model from data is to recover its network structure, while the model parameters are of minor interest. For example, we may wish to recover regulatory networks from high-throughput data ...
Properties and Applications of Shape Recipes
(2002-12-01)
In low-level vision, the representation of scene properties such as shape, albedo, etc., are very high dimensional as they have to describe complicated structures. The approach proposed here is to let the image itself ...
Recovering Intrinsic Images from a Single Image
(2002-09-01)
We present an algorithm that uses multiple cues to recover shading and reflectance intrinsic images from a single image. Using both color information and a classifier trained to recognize gray-scale patterns, each image ...
Implementing Universal Computation in an Evolutionary System
(2002-07-01)
Evolutionary algorithms are a common tool in engineering and in the study of natural evolution. Here we take their use in a new direction by showing how they can be made to implement a universal computer. We consider ...
Context-Based Vision System for Place and Object Recognition
(2003-03-19)
While navigating in an environment, a vision system has to be able to recognize where it is and what the main objects in the scene are. In this paper we present a context-based vision system for place and object ...
Shape Recipes: Scene Representations that Refer to the Image
(2002-09-01)
The goal of low-level vision is to estimate an underlying scene, given an observed image. Real-world scenes (e.g., albedos or shapes) can be very complex, conventionally requiring high dimensional representations which ...
The Role of Programming in the Formulation of Ideas
(2002-11-01)
Classical mechanics is deceptively simple. It is surprisingly easy to get the right answer with fallacious reasoning or without real understanding. To address this problem we use computational techniques to communicate ...
(Semi-)Predictive Discretization During Model Selection
(2003-02-25)
In this paper, we present an approach to discretizing multivariate continuous data while learning the structure of a graphical model. We derive the joint scoring function from the principle of predictive accuracy, which ...
Persistent Nodes for Reliable Memory in Geographically Local Networks
(2003-04-15)
A Persistent Node is a redundant distributed mechanism for storing a key/value pair reliably in a geographically local network. In this paper, I develop a method of establishing Persistent Nodes in an amorphous matrix. I ...
