Can Basic ML Techniques Illuminate Rateless Erasure Codes?
(2004-05-05)
The recently developed rateless erasure codes are a near-optimal channel coding technique that guaranteeslow overhead and fast decoding. The underlying theory, and current implementations, of thesecodes assume that a network ...
On Verifying a File System Implementation
(2004-05-06)
We present a correctness proof for a basic file system implementation. This implementation contains key elements of standard Unix file systems such as inodes and fixed-size disk blocks. We prove the implementation correct ...
Video Matching
(2004-05-11)
This paper describes a method for bringing two videos (recorded at different times) into spatiotemporal alignment, then comparing and combining corresponding pixels for applications such as background subtraction, compositing, ...
Shape Representation in V4: Investigating Position-Specific Tuning for Boundary Conformation with the Standard Model of Object Recognition
(2004-11-12)
The computational processes in the intermediate stages of the ventral pathway responsible for visual object recognition are not well understood. A recent physiological study by A. Pasupathy and C. Connor in intermediate ...
Efficient Image Matching with Distributions of Local Invariant Features
(2004-11-22)
Sets of local features that are invariant to common image transformations are an effective representation to use when comparing images; current methods typically judge feature sets' similarity via a voting scheme (which ...
Neural Network Models for Zebra Finch Song Production and Reinforcement Learning
(2004-11-09)
The zebra finch is a standard experimental system for studying learning and generation of temporally extended motor patterns. The first part of this project concerned the evaluation of simple models for the operation and ...
A new biologically motivated framework for robust object recognition
(2004-11-14)
In this paper, we introduce a novel set of features for robust object recognition, which exhibits outstanding performances on a variety ofobject categories while being capable of learning from only a fewtraining examples. ...
Availability-Consistency Trade-Offs in a Fault-Tolerant Stream Processing System
(2004-11-22)
processing. In contrast to previous techniques that handlenode failures, our approach also tolerates network failuresand network partitions. The approach is based on a principledtrade-off between consistency and availability ...
Comparing Network Coding with Multicommodity Flow for the k-pairs Communication Problem
(2004-11-24)
Given a graph G = (V,E) and k source-sink pairs of vertices, this papers investigates the maximum rate r at which all pairs can simultaneously communicate. We view this problem from two perspectives and compare their ...
Learning with Matrix Factorizations
(2004-11-22)
Matrices that can be factored into a product of two simpler matricescan serve as a useful and often natural model in the analysis oftabulated or high-dimensional data. Models based on matrixfactorization (Factor Analysis, ...
