EDGE-BASED LOCALLY AGGREGATED DESCRIPTORS FOR IMAGE CLUSTERING
Edge feature points Local feature aggregation Global image descriptors Image clustering
2018/5/11
The current global image descriptors are mostly obtained by using the local image features aggregation, which fail to take full account of the details of the image, resulting in the loss of the semant...
Finite sample forecasting with estimated temporally aggregated linear processes
linearmodels ARMA temporal aggregation forecasting finite sample forecasting flow temporal aggregation stock temporal aggregation multistep forecasting
2012/11/22
We propose a finite sample based predictor for estimated linear one dimensional time series models and compute the associated total forecasting error. The expression for the error that we present take...
Systematics in Aggregated Neutrino Fluxes and Flavor Ratios from Gamma-Ray Bursts
Systematics Aggregated Neutrino Fluxes Flavor Ratios Gamma-Ray Bursts
2011/10/20
Gamma-ray burst analyses at neutrino telescopes are typically based on diffuse or stacked (i.e., aggregated) neutrino fluxes, because the number of events expected from a single burst is small. The ag...
A Hierarchical Model for Aggregated Functional Data
Bayes'theorem B-splines Covariance function Gaussian process
2011/3/21
In many areas of science one aims to estimate latent sub-population mean curves based only on observations of aggregated population curves. By aggregated curves we mean linear combination of functiona...
Improved Aggregated Impairment Information for Bi-directional Lightpath Establishments
Fibre optics an optical communication All-optical networks
2015/6/8
We propose a set of physical parameters for GMPLS signaling to establish bi-directional paths.This reduces the amount of flooded information and speeds-up the path establishment while keeping its risk...
Approaches for Multi-step Density Forecasts with Application to Aggregated Wind Power
Non-Gaussian time series logistic transformation exponentialsmoothing truncated normal distribution ARIMA-GARCH model
2010/3/11
The generation of multi-step density forecasts for non-Gaussian
data mostly relies on Monte-Carlo simulations which are computa-
tionally intensive. Using aggregated wind power in Ireland, we study

A centroid-based performance evaluation using aggregated fuzzy numbers
Aggregated fuzzy numbers centroid index
2010/9/15
In recent years, some methods have been proposed in solving performance evaluation issues by using fuzzy set theory. In this paper, an improvised method for performance evaluation under fuzzy environm...
Estimation of the impact of short-term fluctuations in inputs on temporally aggregated outputs of process-oriented models
short-term fluctuations inputs outputs process-oriented models
2009/12/4
Process-oriented models driven by highly resolved meteorological inputs and comprising a short internal time step are sometimes used to predict substance fluxes in air, soil and water over fairly long...
Eco-taphonomy of mass-aggregated giant balanids Concavus (Concavus) concavus (DARWIN, 1854) from the Lower Pliocene (Zanclean) of Rafina near Pikermi (Attica,Greece)
Eco-taphonomy Cirripedes Balanids Concavus Pliocene (Zanclean)
2009/10/20
The large- to giant-sized balanids, mass-aggregated in a tempestite of the Lower Pliocene (Zanclean) section at Rafina near Pikermi,Greece, represent a single species, Concavus (Concavus) concavus (DA...

Database outsourcing is a popular industry trend which involves organizations delegating their data
management needs to an external service provider. In this model, a service provider hosts its clien...
Longitudinal dispersion in natural channels: 3. An aggregated dead zone model applied to the River Severn, U.K.
Channels ispersion dead zones tracers
2009/3/24
An Aggregated Dead Zone (ADZ) model is presented for longitudinal dispersion of tracer in river channels, in which the channel cross-section is divided into two parallel regions: the bulk flow and dea...
WANDA, a regional dynamic nitrogen model (With Aggregated Nitrogen DynAmics) for nitrate leaching from forests
nitrogen nitrate forest model
2009/3/6
Nitrate concentrations in recently infiltrated groundwater in forested areas in the Netherlands are slowly increasing towards the EU limit of 50 mg NO3 l–1. The origin of this nitrate is thought to be...
Harvest block spatial configuration as a function of logging road density：Do larger more aggregated blocks create less road?
Harvest block spatial configuration logging road density
2009/2/5
Logging roads are a large component of forest management and have been directly linked to a variety of negative ecological effects, including forest fragmentation. Much research exists that views logg...
