The Project of the Italian Culture Portal. A Standard Based Model for Interoperability Amongst Cultural Heritage Data Sources
Classification Cultural Heritage ata structures Interface Interoperability
2015/11/13
The paper describes the scientific and technical project carried out by SNS for the Italian Culture Portal, promoted by Italian Ministry of Cultural Heritage and Activities, as a media for knowledge a...
A two-layer sparse coding model learns simple and complex cell receptive fields and topography from natural images
Independent component analysis Natural images Neural networks Spatial vision
2015/8/10
The classical receptive fields of simple cells in the visual cortex have been shown to emerge from the statistical properties of natural images by forcing the cell responses to be maximally sparse, i....
Predictive Coding as a Model of Biased Competition in Visual Attention
neural networks cortical circuits cortical feedback attention binding problem
2015/7/29
Attention acts, through cortical feedback pathways, to enhance the response of cells encoding expected or predicted information. Such observations are inconsistent with the predictive coding theory of...
A Probabilistic Model of Hierarchical Music Analysis
computational music analysis computational music theory machine learning music informatics Schenkerian analysis
2014/12/18
Schenkerian music theory supposes that Western tonal compositions can be viewed as hierarchies of musical objects. The process of Schenkerian analysis reveals this hierarchy by identifying connections...
Model-Driven Analytics of Energy Meter Data in Smart Homes
energy smart meter modeling NILM
2014/12/18
The proliferation of smart meter deployments has led to significant interest in analyzing home energy use as part of the emerging 'smart grid'. As buildings account for nearly 40% of society's energy ...
Scientists say new computer model amounts to a lot more than a hill of beans

2014/4/16
CHAMPAIGN, Ill. — Crops that produce more while using less water seem like a dream for a world with a burgeoning population and already strained food and water resources. This dream is coming closer t...
AN ADAPTIVE INTEGRATION MODEL OF VECTOR POLYLINE TO DEM DATA BASED ON SPHERICAL DEGENERATE QUADTREE GRIDS
Adaptive integration DQG DEM Vector polyline Shift algorithm
2014/4/21
Traditional geometry-based approach can maintain the characteristics of vector data. However, complex interpolation calculations
limit its applications in high resolution and multi-source spatial da...
COMPARISON OF PARTICLE SWARM OPTIMIZATION AND GENETIC ALGORITHM IN RATIONAL FUNCTION MODEL OPTIMIZATION
Rational Function Model (RFM) Particle Swarm Optimization (PSO) Genetic Algorithm (GA) Mathematical Modelling High Resolution Satellite Images (HRSIs)
2014/4/25
Rational Function Models (RFM) are one of the most considerable approaches for spatial information extraction from satellite images especially where there is no access to the sensor parameters. As the...
Bayesian and Non-Bayesian Estimation of the Inverse Weibull Model Based on Generalized Order Statistics
Inverse Weibull Distribution Generalized Order Statistics Record Values Progressive Type-II Censored Balanced Type Loss Function Bootstrap Estimation
2013/1/28
The concept of generalized order statistics has been introduced as a unified approach to a variety of models of ordered random variables with different interpretations. In this paper, we develop metho...
The Collision Security of Tandem-DM in the Ideal Cipher Model
Collision Security Tandem-DM Cipher Model
2012/12/3
We prove that Tandem-DM, which is one of the two “classical” schemes for turning a blockcipher of 2n-bit key into a double block length hash function, has birthday-type collision resistance in the ide...
The Limits of Buffering: A Tight Lower Bound for Dynamic Membership in the External Memory Model
Data Structures External Memory Membership
2012/12/3
We study the dynamic membership (or dynamic dictionary) problem, which is one of the most fundamental problems in data structures. We study the problem in the external memory model with cell size b bi...
Information Warfare: using the viable system model as a framework to attack organisations
Information Warfare viable system model framework attack organisations
2009/12/8
Information is the glue in any organization. It is needed for policy, decision-making, control, and co-ordination. If an organisation's information systems are disrupted or destroyed, then damage to t...
