ABSTRACT In this series of papers, we present a simulation-based model for the non-linear clustering galaxies based on separate modelling in real space and velocity statistics. first paper, an emulator real-space correlation function galaxies, whereas real-to-redshift mapping statistics is presented second paper. Here, show that neural network galaxy trained data extracted from dark quest suite...

Human sentence processing occurs incrementally. Most models of human processing rely on parsers that always build connected tree structures. But according to the theory of Good Enough parsing (Ferreira & Patson, 2007), humans parse sentences using small chunks of local information, not always forming a globally coherent parse. This difference is apparent in the study of local coherence effects ...

A video analysis framework based on spatiotemporal saliency calculation is presented. We propose a novel scheme for generating saliency in video sequences by taking into account both the spatial extent and dynamic evolution of regions. Towards this goal we extend a common image-oriented computational model of saliency-based visual attention to handle spatiotemporal analysis of video in a volume...

This paper presents a skill learning model Clarion. Diierent from existing models of mostly high-level skill learning that use a top-down approach (that is, turning declarative knowledge into procedural knowledge), we adopt a bottom-up approach toward low-level skill learning, where procedural knowledge develops rst and declarative knowledge develops from it. Clarion which follows this approach...

The results of calculations made by bottom-up linear optimization models (LP) are to some extent determined by the applied optimization strategy. Existing energy system models most commonly employ an optimization strategy which are known as perfect-foresight, i.e. an optimization of the total time period in one system of equations. Perfect foresight means that the model in principle would “know...

This paper is concerned with the bottom-up hierarchical system and public debate model proposed by Galam (2008), as well as a spatial version of the public debate model. In all three models, there is a population of individuals who are characterized by one of two competing opinions, say opinion −1 and opinion +1. This population is further divided into groups of common size s. In the bottom-up ...

Research on automatically solving mathematical word problems (MWP) has a long history. Most recent works adopt Seq2Seq approach to predict the result equations as sequence of quantities and operators. Although can be written sequence, it is essentially structure. More precisely, Direct Acyclic Graph (DAG) whose leaf nodes are quantities, internal root arithmetic or comparison In this paper, we ...
