Data compression and definability of types in stable and dependent formulas.
Partition Reduction for Lossy Data Compression Problem
Partition Reduction Lossy Data Compression Problem Information Theory
2012/4/17
We consider the computational aspects of lossy data compression problem, where the compression error is determined by a cover of the data space. We propose an algorithm which reduces the number of par...
A New Method of Data Compression in Multisensor Estimation Fusion
Parameter estimation data compression Bayesian decision
2011/11/7
Consider the decentralized estimation of an unknown parameter by bandwidth constrained sensor network with a fusion center. Local sensors make observations which are linearly scaled versions of these ...
Accelerating Lossless Data Compression with GPUs
Accelerating Lossless Data GPUs Information Theory Graphics
2011/8/30
Abstract: Huffman compression is a statistical, lossless, data compression algorithm that compresses data by assigning variable length codes to symbols, with the more frequently appearing symbols give...
Subset sum phase transitions and data compression
Number partitioning integer partitioning subset sum data compression source coding entropy phase transitions
2011/9/6
Abstract: We propose a rigorous analysis approach for the subset sum problem in the context of lossless data compression, where the phase transition of the subset sum problem is directly related to th...
SPECTRAL MATCHING THROUGH DATA COMPRESSION
Spectral distance similarity measure data compression
2014/6/5
This paper proposes to use compression-based similarity measures to cluster spectral signatures on the basis of their similarities. Such
universal distances estimate the shared information between tw...
A New Technique for Text Data Compression
Coding Data Compression Binary system Ternary System Golden Ratio
2011/3/3
In this paper we use ternary representation of numbers for compressing text data. We
use a binary map for ternary digits and introduce a way to use the binary 11-pair, which has never been use for co...
An investigation into the MOPED data compression algorithm
the MOPED data compression algorithm Astrophysics
2011/1/13
We investigate the use of the MOPED algorithm (\cite{MOPED1}) for data compression and faster evaluation of likelihood functions. Since MOPED only guarantees maintaining the Fisher matrix of the likel...
A Coder-Decoder model for use in Lossless Data Compression
A Coder-Decoder model Data Compression
2010/11/24
This article describes a technique of using a trigonometric function and combinatorial calculations to code or transform any finite sequence of binary numbers (0s and 1s) of any length to a unique set...
A statistical-mechanical view on source coding: physical compression and data compression
statistical-mechanical physical compression data compression
2010/11/23
We draw a certain analogy between the classical information–theoretic problem of lossy data compression (source coding) of memoryless information sources and the statistical mechanical behavior of a c...
