DryadLINQ: A System for General-Purpose Distributed Data-Parallel Computing Using a High-Level Language

by Yuan Yu, Michael Isard, Dennis Fetterly, Mihai Budiu, Úlfar Erlingsson, Pradeep Kumar, Gunda Jon Currey
"... DryadLINQ is a system and a set of language extensions that enable a new programming model for large scale distributed computing. It generalizes previous execution environments such as SQL, MapReduce, and Dryad in two ways: by adopting an expressive data model of strongly typed.NET objects; and by s ..."

made up of thousands of computers, ensures efficient, reliable execution of this plan. We describe the implementation of the DryadLINQ compiler and runtime. We evaluate DryadLINQ on a varied set of programs drawn from domains such as web-graph analysis, large-scale log mining, and machine learning. We

Random-walk computation of similarities between nodes of a graph, with application to collaborative recommendation

by Francois Fouss , Alain Pirotte , Jean-Michel Renders , Marco Saerens - IEEE Transactions on Knowledge and Data Engineering
"... ABSTRACT This work presents a new perspective on characterizing the similarity between elements of a database or, more generally, nodes of a weighted, undirected, graph. It is based on a Markov-chain model of random walk through the database. More precisely, we compute quantities (the average commu ..."

A procedure for computing the subspace projection of the node vectors of the graph that preserves as much variance

HadoopDB: An Architectural Hybrid of MapReduce and DBMS Technologies for Analytical Workloads

by Azza Abouzeid, Kamil Bajda-pawlikowski, Daniel Abadi, Avi Silberschatz, Er Rasin
"... The production environment for analytical data management applications is rapidly changing. Many enterprises are shifting away from deploying their analytical databases on high-end proprietary machines, and moving towards cheaper, lower-end, commodity hardware, typically arranged in a shared-nothing ..."

Dynamic Alignment Kernels

by Chris Watkins - Advances in Large Margin Classifiers , 1999
"... There is much current interest in kernel methods for classification, regression, PCA, and other linear methods of data analysis. Kernel methods may be particularly valuable for problems in which the input data is not readily described by explicit feature vectors. One such problem is where input data ..."
