Low rate distributed quantization of noisy observations
Quantitative distributed network nodes a random variable
2015/8/13
We consider the achievable performance of a network of nodes in which the nodes view a common random variable corrupted by a site specific noise and share low rate information about their observations...
Anisotropic oracle inequalities in noisy quantization
Quantization Deconvolution Fast rates Margin assumption,k-means clus-tering
2013/6/13
The effect of errors in variables in quantization is investigated. We prove general exact and non-exact oracle inequalities with fast rates for an empirical minimization based on a noisy sample $Z_i=X...
Distributed Functional Scalar Quantization Simplified
Distributed Functional Scalar Quantization Simplified Information Theory
2012/6/25
Distributed functional scalar quantization (DFSQ) theory provides optimality conditions and predicts performance of data acquisition systems in which a computation on acquired data is desired. We addr...
Asymptotically optimal parameter estimation under quantization constraints
Asymptotically quantization constraints parameter estimation
2011/3/18
The problem of decentralized parameter estimation is considered for diffusion-type processes whose drift coefficients are linear with respect to the unknown parameter. This problem is motivated by app...
Density quantization method in the optimal portfolio choice with partial observation of stochastic volatility
Optimal portfolio partial observation ltering density
2010/10/21
Computational aspects of the optimal consumption and investment with the partially observed stochastic volatility of the asset prices are considered. The new quantization approach to filtering - dens...
Tolerance of the ERP Signatures of Unfamiliar versus Familiar Face Perception to Spatial Quantization of Facial Images
Face Recognition Spatial Quantization N170 P300 Deception
2013/2/23
Processing of faces as stimuli is known to be associated with a conspicuous ERP component N170. Processing of fa-miliar faces is found to be associated with an increased amplitude of the ERP component...
On the use of self-organizing maps to accelerate vector quantization
use self-organizing maps vector quantization
2010/4/26
Self-organizing maps (SOM) are widely used for their topology preservation property: neighboring input vectors are quantified (or classified) either on the same location or on neighbor ones on a prede...
Forecasting the CATS benchmark with the Double Vector Quantization method
Time Series prediction CATS competition Double Vector Quantization method
2010/4/27
The Double Vector Quantization method, a long-term forecasting method based
on the SOM algorithm, has been used to predict the 100 missing values of the
CATS competition data set. An analysis of the...

FREQUENCY CONTENT ORIENTED MODIFICATION OF QUANTIZATION MATRIX IN DCT – BASED COMPRESSION
Image compression quantization matrix
2010/1/12
In order to improve the compression rate for comparable values of error metrics, we propose a method to modify the standard quantization matrix used in JPEG, according to image frequency content. Unli...
Static Gesture Quantization and DCT Based Sign Language Generation,
Static Gesture Quantization DCT Based Sign Language Generation
2010/12/15
To collect data for sign language recognition is not a trivial task. The lack of training data has become a bottleneck in the research of singer in-dependence and large vocabulary recognition. A novel...
A Study on the Quantization Scheme in H.264/AVC and Its Application to Rate Control
Quantization Scheme H.264/AVC Rate Control
2010/12/14
Compared with previous video coding standards,H.264/AVC employs a division-free quantization scheme. The relation
between quantization parameter and quantization step changes from general linear to e...
