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...
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, ...
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...
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...
Extracting Hierarchical Rules from a Weighted Alignment Matrix
Extracting Hierarchical Rules Weighted Alignment Matrix
2013/4/22
Word alignment is a fundamental step in machine translation. Current statistical machine translation systems suffer from a major drawback: they only extract rules from 1-best alignments, which adverse...
Hierarchical fuzzy controller applied to multi-input power system stabilizer
Power system stabilizer (PSS) hierarchical fuzzy system (HFS) inter-area oscillation fuzzy logic controllers damping
2010/10/12
This paper proposes the application of a hierarchical fuzzy system (HFS) based on multi-input power system stabilizer (MPSS) in multi-machine environment. The number of rules increases exponentially w...
Addendum to: An Approach to Hierarchical Clustering via Level Surfaces and Convexity
Hierarchical Clustering Level Sets Level Surfaces Radial Basis Function Convex Heat Gravity Light Cluster Validation Ridge Path Euclidean Distance Manhattan Distance Metric
2013/1/29
This article is an addendum to the 2001 paper [1] which investigated an approach to hierarchical clustering based on the level sets of a density function induced on data points in a d-dimensional feat...
Multi-task learning is the problem of maxi-mizing the performance of a system across a number of related tasks. When applied to mul-tiple domains for the same task, it is similar to domain adaptation,...
优化的Hierarchical B码率控制算法
可伸缩编码 码率控制 率失真优化
2009/10/9
H.264/AVC可伸缩视频编码系统（SVC）在时间域采用的可分级B帧（Hierarchical B）结构，与传统的IPPP或者IBBP编码结构相比，编码性能有较大提高。其采用调整单位时间内编码和显示的图像帧数来适应不同的码率。但信道带宽变化较大时，帧率波动较大，会造成视频的不连续性。因此，针对各分层不同特点给出相应的码率控制方案，并通过对B帧选择合适的量化参数限制图像帧率的波动范围。实验结果表明...
