Information Dissemination and Aggregation in Asset Markets with Simple Intelligent Traders
(1998-09-01)Various studies of asset markets have shown that traders are capable of learning and transmitting information through prices in many situations. In this paper we replace human traders with intelligent software agents ...

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 ...

Learning-Based Approach to Real Time Tracking and Analysis of Faces
(1999-09-23)This paper describes a trainable system capable of tracking faces and facialsfeatures like eyes and nostrils and estimating basic mouth features such as sdegrees of openness and smile in real time. In developing this ...

Rotation Invariant Real-time Face Detection and Recognition System
(2001-05-31)In this report, a face recognition system that is capable of detecting and recognizing frontal and rotated faces was developed. Two face recognition methods focusing on the aspect of pose invariance are presented and ...

A Note on Object Class Representation and Categorical Perception
(1999-12-17)We present a novel scheme ("Categorical Basis Functions", CBF) for object class representation in the brain and contrast it to the "Chorus of Prototypes" scheme recently proposed by Edelman. The power and flexibility ...

A Note on the Generalization Performance of Kernel Classifiers with Margin
(2000-05-01)We present distribution independent bounds on the generalization misclassification performance of a family of kernel classifiers with margin. Support Vector Machine classifiers (SVM) stem out of this class of machines. The ...

Building Grounded Abstractions for Artificial Intelligence Programming
(2004-06-16)Most Artificial Intelligence (AI) work can be characterized as either ``high-level'' (e.g., logical, symbolic) or ``low-level'' (e.g., connectionist networks, behavior-based robotics). Each approach suffers from particular ...

BioJADE: A Design and Simulation Tool for Synthetic Biological Systems
(2004-05-28)The next generations of both biological engineering and computer engineering demand that control be exerted at the molecular level. Creating, characterizing and controlling synthetic biological systems may provide us ...

Learning Commonsense Categorical Knowledge in a Thread Memory System
(2004-05-18)If we are to understand how we can build machines capable of broad purpose learning and reasoning, we must first aim to build systems that can represent, acquire, and reason about the kinds of commonsense knowledge that ...

Generative Temporal Planning with Complex Processes
(2004-05-18)Autonomous vehicles are increasingly being used in mission-critical applications, and robust methods are needed for controlling these inherently unreliable and complex systems. This thesis advocates the use of model-based ...
-
Fluorescence Assay for Polymerase Arrival Rates
(2003-08-31)To engineer complex synthetic biological systems will require modular design, assembly, and characterization strategies. The RNA polymerase arrival rate (PAR) is defined to be the rate that RNA polymerases arrive at a ...

Representation and Detection of Shapes in Images
(2003-08-08)We present a set of techniques that can be used to represent and detect shapes in images. Our methods revolve around a particular shape representation based on the description of objects using triangulated polygons. This ...
-
Compact Representations for Fast Nonrigid Registration of Medical Images
(2003-07-04)We develop efficient techniques for the non-rigid registration of medical images by using representations that adapt to the anatomy found in such images. Images of anatomical structures typically have uniform intensity ...
-
Gait Analysis for Classification
(2003-06-26)This thesis describes a representation of gait appearance for the purpose of person identification and classification. This gait representation is based on simple localized image features such as moments extracted from ...

Teaching an Old Robot New Tricks: Learning Novel Tasks via Interaction with People and Things
(2003-06-20)As AI has begun to reach out beyond its symbolic, objectivist roots into the embodied, experientialist realm, many projects are exploring different aspects of creating machines which interact with and respond to the world ...
-
Online Learning of Non-stationary Sequences
(2003-06-12)We consider an online learning scenario in which the learner can make predictions on the basis of a fixed set of experts. The performance of each expert may change over time in a manner unknown to the learner. We formulate ...

Safe Distributed Coordination of Heterogeneous Robots through Dynamic Simple Temporal Networks
(2003-05-30)Research on autonomous intelligent systems has focused on how robots can robustly carry out missions in uncertain and harsh environments with very little or no human intervention. Robotic execution languages such as RAPs, ...

From First Contact to Close Encounters: A Developmentally Deep Perceptual System for a Humanoid Robot
(2003-06-01)This thesis presents a perceptual system for a humanoid robot that integrates abilities such as object localization and recognition with the deeper developmental machinery required to forge those competences out of raw ...

A Statistical Image-Based Shape Model for Visual Hull Reconstruction and 3D Structure Inference
(2003-05-22)We present a statistical image-based shape + structure model for Bayesian visual hull reconstruction and 3D structure inference. The 3D shape of a class of objects is represented by sets of contours from silhouette ...

Segmentation and Alignment of Speech and Sketching in a Design Environment
(2003-02-01)Sketches are commonly used in the early stages of design. Our previous system allows users to sketch mechanical systems that the computer interprets. However, some parts of the mechanical system might be too hard or too ...
