Modeling Invariances in Inferotemporal Cell Tuning
(1998-03-01)
In macaque inferotemporal cortex (IT), neurons have been found to respond selectively to complex shapes while showing broad tuning ("invariance") with respect to stimulus transformations such as translation and scale changes ...
Sparse Correlation Kernel Analysis and Reconstruction
(1998-05-01)
This paper presents a new paradigm for signal reconstruction and superresolution, Correlation Kernel Analysis (CKA), that is based on the selection of a sparse set of bases from a large dictionary of class- specific basis ...
Slow and Smooth: A Bayesian Theory for the Combination of Local Motion Signals in Human Vision
(1998-02-01)
In order to estimate the motion of an object, the visual system needs to combine multiple local measurements, each of which carries some degree of ambiguity. We present a model of motion perception whereby measurements ...
Estimating Dependency Structure as a Hidden Variable
(1998-09-01)
This paper introduces a probability model, the mixture of trees that can account for sparse, dynamically changing dependence relationships. We present a family of efficient algorithms that use EM and the Minimum Spanning ...
From Regression to Classification in Support Vector Machines
(1998-11-01)
We study the relation between support vector machines (SVMs) for regression (SVMR) and SVM for classification (SVMC). We show that for a given SVMC solution there exists a SVMR solution which is equivalent for a certain ...
PrologPF: Parallel Logic and Functions on the Delphi Machine
(University of CambridgeComputer LaboratoryGirton College, 1998-06-16)
PrologPF is a parallelising compiler targeting a distributed system of general purpose workstations connected by a relatively low performance network. The source language extends standard Prolog with the integration of ...
An Algorithm for Group Formation and Maximal Independent Set in an Amorphous Computer
(1998-02-01)
Amorphous computing is the study of programming ultra-scale computing environments of smart sensors and actuators cite{white-paper}. The individual elements are identical, asynchronous, randomly placed, embedded and ...
Restructuring Sparse High Dimensional Data for Effective Retrieval
(1998-05-01)
The task in text retrieval is to find the subset of a collection of documents relevant to a user's information request, usually expressed as a set of words. Classically, documents and queries are represented as vectors ...
Direct Estimation of Motion and Extended Scene Structure from a Moving Stereo Rig
(1998-12-01)
We describe a new method for motion estimation and 3D reconstruction from stereo image sequences obtained by a stereo rig moving through a rigid world. We show that given two stereo pairs one can compute the motion of the ...
Separating Reflections from Images Using Independent Components Analysis
(1998-09-01)
The image of an object can vary dramatically depending on lighting, specularities/reflections and shadows. It is often advantageous to separate these incidental variations from the intrinsic aspects of an image. Along these ...
