Language Support for Dynamic, Hierarchical Data Partitioning
Legion regions type system independence aliasing hierarchical scheduling
2016/5/24
Applications written for distributed-memory parallel architectures must partition their data to enable parallel execution.As memory hierarchies become deeper, it is increasingly necessary that the dat...
Estimating Heterogeneous and Hierarchical Peer Effects on Body Weight Using Roommate Assignments as a Natural Experiment
Heterogeneous Hierarchical Peer Body Weight Roommate Assignments Natural Experiment
2016/3/3
We investigate peer effects in weight gain by exploiting a natural experiment, roommate assignments of 751 male and 845 female first-year college students. Results indicate that females are subject to...
Query Understanding Enhanced by Hierarchical Parsing Structures
query understanding semantic tagging linguistic parsing
2016/1/23
Query understanding has been well studied in the areas of information retrieval and spoken language understanding(SLU). There are generally three layers of query understanding: domain classification, ...
An Approach to Building Grouping Based on Hierarchical Constraints
Building generalization building grouping hierarchical constraints Gestalt factors minimum spanning tree
2015/12/2
Building generalization is one of the difficult operations in automated map generalization. It usually consists of two consecutive steps, i.e. dividing buildings into groups (also called building grou...
Learning interactions via hierarchical group-lasso regularization
hierarchical interaction computer intensive regression logistic
2015/8/21
We introduce a method for learning pairwise interactions in a linear regression or logistic regression model in a manner that satisfies strong hierarchy: whenever an interaction is estimated to be non...
Hierarchical Identity Based Encryption with Constant Size Ciphertext
Constant Size Ciphertext Based Encryption
2015/8/5
We present a Hierarchical Identity Based Encryption (HIBE) system where the ciphertext consists of just three group elements and decryption requires only two bilinear map computations, independent of ...
Lattice basis delegation in fixed dimension and shorter ciphertext hierarchical IBE
ciphertext hierarchical IBE fixed dimensio
2015/8/5
We present a technique for delegating a short lattice basis that has the advantage of keeping the lattice dimension unchanged upon delegation. Building on this result, we construct two new hierarchica...
Realistic description of causality in truly complex hierarchical structures
Unreduced dynamic complexity universal science of complexity emergent consciousness causally complete knowledge
2015/8/3
In his recent essay article entitled "Physics, Complexity and Causality" (Nature 435, 743; 2005) George Ellis states that despite well-known successes of physics "we still do not have a realistic desc...
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...
Coacervation of Oppositely Charged Macromolecules, Micelles and Proteins: Disproportionation and Hierarchical Structures
coacervation complexation phase transitions
2014/11/20
Analogous disproportionation processes lead to similarities in the structures present at incipient coacervation to those within the subsequent dense phase. Coacervation in polyelectrolyte/mixed micell...
A GLOBAL HIERARCHICAL AND EQUAL-AREA SHPERE/ ELLIPSOID GRID AND ITS GEOMETRY DISTORTION ANALYSIS
Global Discrete Gird Hierarchical Grid Equal-Area Snyder Projection Geometry Distortion Analysis Sphere Surface
2014/4/21
A spatial data management and analysis frame is required for global problem application. Global Discrete Grid (GDG) has seamless,
excellent hierarchy characteristics. GDG has been used for spatial d...
An Infinite Hierarchical Bayesian Model of Phrasal Translation
An Infinite Hierarchical Bayesian Model Phrasal Translation
2014/3/20
Modern phrase-based machine translation systems make extensive use of wordbased translation models for inducing alignments from parallel corpora. This is problematic, as the systems are incapable of a...
Conjugate distributions in hierarchical Bayesian ANOVA for computational efficiency and assessments of both practical and statistical significance
ANOVA xed eects random eects variance components hierar-chical Bayes multilevel model constraints
2013/4/27
Assessing variability according to distinct factors in data is a fundamental technique of statistics. The method commonly regarded to as analysis of variance (ANOVA) is, however, typically confined to...
Hierarchical array priors for ANOVA decompositions
array-valued data Bayesian estimation cross-classi ed data factorial design MANOVA penalized regression tensor Tucker product sparse data.
2012/9/17
ANOVA decompositions are a standard method for describing and estimating heterogeneity among the means of a response variable across levels of multiple categorical factors. In such a decomposition, th...
Hierarchical Clustering using Randomly Selected Similarities
Hierarchical Clustering Randomly Selected Similarities
2012/9/19
The problem of hierarchical clustering items from pairwisesimilarities is found across various scientific disciplines, from biology to networking. Often, applications of clustering techniques are limi...
