This paper reconsiders the aliasing problem of identifying the parameters of a continuous time stochastic process from discrete time data. It analyzes the extent to which restricting attention to processes with rational spectral density matrices reduces the number of observationally equivalent models. It...
The dimensionality of such problem usually depends on the number of bixels in which each radiation field is divided. Recently, the efforts have been put on finding arrangements of small segments (subfields) irradiating uniformly. In this paper a deterministic algorithm which allows to find solutions...
points in high dimensional spaces. In particular, we consider the problem of whether a single data point that is randomly chosen from a finite set of points can be separated from the rest of the data set by a linear hyperplane. We formulate and prove stochastic separation theorems, including:...
Thermal resolution (also referred to as temperature uncertainty) establishes the minimum discernible temperature change sensed by luminescent thermometers and is a key figure of merit to rank them. Much has been done to minimize its value via probe optim
For dimensionality D=2, the value is obtained exactly by exploiting the properties of the dual lattice. In three dimensions a potential problem is solved approximately on a 34*34*34 computer-simulated cubic lattice. For infinite ... PM Kogut,JP Straley - 《Journal of Physics C Solid State ...

Query and document representation is a key problem for information retrieval and filtering. The vector space model (VSM) has been widely used in this domain. But the VSM suffers from high dimensionality. The vectors built from documents always have high dimensionality and contain too much noise. ...
In principle, the optimal dimension may be tested on data from a variety of areas. Here we consider the problem of the large-scale structure of the universe. Sky surveys and mappings of the various wavelength bands of electromagnetic radiation have yielded information on the content and character...
