Intelligent Market-Making in Artificial Financial Markets
(2003-06-01)
This thesis describes and evaluates a market-making algorithm for setting prices in financial markets with asymmetric information, and analyzes the properties of artificial markets in which the algorithm is used. The ...
Face Representation in Cortex: Studies Using a Simple and Not So Special Model
(2003-06-05)
The face inversion effect has been widely documented as an effect of the uniqueness of face processing. Using a computational model, we show that the face inversion effect is a byproduct of expertise with respect to the ...
A Biological Model of Object Recognition with Feature Learning
(2003-06-01)
Previous biological models of object recognition in cortex have been evaluated using idealized scenes and have hard-coded features, such as the HMAX model by Riesenhuber and Poggio [10]. Because HMAX uses the same set ...
Dissociated Dipoles: Image representation via non-local comparisons
(2003-08-13)
A fundamental question in visual neuroscience is how to represent image structure. The most common representational schemes rely on differential operators that compare adjacent image regions. While well-suited to encoding ...
On The Boolean Algebra of Shape Analysis Constraints
(2003-08-22)
Shape analysis is a promising technique for statically verifyingand extracting properties of programs that manipulatecomplex data structures. We introduce a new characterizationof constraints that arise in parametric ...
Permutation Tests for Classification
(2003-08-28)
We introduce and explore an approach to estimating statisticalsignificance of classification accuracy, which is particularly usefulin scientific applications of machine learning where highdimensionality of the data and the ...
Direction Estimation of Pedestrian from Images
(2003-08-27)
The capability of estimating the walking direction of people would be useful in many applications such as those involving autonomous cars and robots.We introduce an approach for estimating the walking direction of people ...
Fluorescence Assay for Polymerase Arrival Rates
(2003-08-31)
To engineer complex synthetic biological systems will require modulardesign, assembly, and characterization strategies. The RNApolymerase arrival rate (PAR) is defined to be the rate that RNApolymerases arrive at a specified ...
Near-Optimal Distributed Failure Circumscription
(2003-08-11)
Small failures should only disrupt a small part of a network. One wayto do this is by marking the surrounding area as untrustworthy ---circumscribing the failure. This can be done with a distributedalgorithm using ...
A Reliable Broadcast Scheme for Sensor Networks
(2003-08-11)
In this short technical report, we present a simple yet effective reliable broadcast protocol for sensor networks. This protocol disseminates packets throughout the sensor network by flooding and recovers from losses ...
