Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Capsule Aggregated Attention for Vehicle Routing Problems
车辆 路径问题 胶囊聚合 关注
2023/4/27
Deep learning based methods have shown great potential for solving Vehicle Routing Problems (VRPs) in recent years. In the current learning based models, attention mechanism plays an important role an...
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...
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 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...
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...
Enhanced of the R6G Thermal Diffusivity on Aggregated Small Gold Particles
Thermal diffusivity Nanofluids Gold nanoparticles Thermal lens
2010/9/29
R6G dye with gold nanoparticles was prepared in water solution. Using a thermal lens experimental setup, the thermal diffusivity of R6G in presence of gold nanoparticles with Au different concentratio...
