Early Sketch Processing with Application in HMM Based Sketch Recognition
(20040728)Freehand sketching is a natural and crucial part of everyday humaninteraction, yet is almost totally unsupported by current user interfaces. With the increasing availability of tablet notebooks and pen based PDAs, sketchbased ... 
Eclat: Automatic Generation and Classification of Test Inputs
(20041014)This paper describes a technique that helps a test engineerselect, from a large set of randomly generated testinputs, a small subset likely to reveal faults in the softwareunder test. The technique takes a program or ... 
Efficient Cache Coherence on Manycore Optical Networks
(20100211)Ever since industry has turned to parallelism instead of frequency scaling to improve processor performance, multicore processors have continued to scale to larger and larger numbers of cores. Some believe that multicores ... 
An Efficient Fill Estimation Algorithm for Sparse Matrices and Tensors in Blocked Formats
(20170609)Tensors, linearalgebraic extensions of matrices in arbitrary dimensions, have numerous applications in computer science and computational science. Many tensors are sparse, containing more than 90% zero entries. Efficient ... 
Efficient Image Matching with Distributions of Local Invariant Features
(20041122)Sets of local features that are invariant to common image transformations are an effective representation to use when comparing images; current methods typically judge feature sets' similarity via a voting scheme (which ... 
An Efficient Learning Procedure for Deep Boltzmann Machines
(20100804)We present a new learning algorithm for Boltzmann Machines that contain many layers of hidden variables. Datadependent statistics are estimated using a variational approximation that tends to focus on a single mode, and ... 
Efficient Marginal Likelihood Optimization in Blind Deconvolution
(20110404)In blind deconvolution one aims to estimate from an input blurred image y a sharp image x and an unknown blur kernel k. Recent research shows that a key to success is to consider the overall shape of the posterior distribution ... 
Efficient Motion Planning Algorithm for Stochastic Dynamic Systems with Constraints on Probability of Failure
(20080306)When controlling dynamic systems such as mobile robots in uncertain environments, there is a trade off between risk and reward. For example, a race car can turn a corner faster by taking a more challenging path. This paper ... 
Efficient Object Recognition and Image Retrieval for LargeScale Applications
(20080506)Algorithms for recognition and retrieval tasks generally call for both speed and accuracy. When scaling up to very large applications, however, we encounter additional significant requirements: adaptability and scalability. ... 
Efficient POMDP Forward Search by Predicting the Posterior Belief Distribution
(20090923)Online, forwardsearch techniques have demonstrated promising results for solving problems in partially observable environments. These techniques depend on the ability to efficiently search and evaluate the set of beliefs ... 
Efficient SpecificationAssisted Error Localization and Correction
(20031113)We present a new error localization tool, Archie, that accepts aspecification of key data structure consistency constraints, then generatesan algorithm that checks if the data structures satisfy theconstraints. We also ... 
Efficient, Verifiable Binary Sandboxing for a CISC Architecture
(20050502)Executing untrusted code while preserving security requiresenforcement of memory and controlflow safety policies:untrusted code must be prevented from modifying memory orexecuting code except as explicitly allowed. ... 
Efficiently Solving Repeated Integer Linear Programming Problems by Learning Solutions of Similar Linear Programming Problems using Boosting Trees
(20150121)It is challenging to obtain online solutions of largescale integer linear programming (ILP) problems that occur frequently in slightly different forms during planning for autonomous systems. We refer to such ILP problems ... 
ElasticNet Regularization in Learning Theory
(20080724)Within the framework of statistical learning theory we analyze in detail the socalled elasticnet regularization scheme proposed by Zou and Hastie ["Regularization and variable selection via the elastic net" J. R. Stat. ... 
Electronic Cash with Blind Deposits: How to Have No Spare Change
(20031014)Electronic cash schemes in which the bank authenticates many coins at once suffer from the problem that coins that are authenticated together can be linked to one another. Unfortunately, unless a user spends coins in a ... 
EM2: A Scalable SharedMemory Multicore Architecture
(20100612)We introduce the Execution Migration Machine (EM2), a novel, scalable sharedmemory architecture for largescale multicores constrained by offchip memory bandwidth. EM2 reduces cache miss rates, and consequently offchip ... 
Embracing Wireless Interference: Analog Network Coding
(20070223)Traditionally, interference is considered harmful.Wireless networks strive to avoid scheduling multiple transmissions at the same time in order to prevent interference. This paper adopts the opposite approach; it encourages ... 
Empirical Effective Dimension and Optimal Rates for Regularized Least Squares Algorithm
(20050527)This paper presents an approach to model selection for regularized leastsquares on reproducing kernel Hilbert spaces in the semisupervised setting. The role of effective dimension was recently shown to be crucial in the ... 
Encrypted Keyword Search in a Distributed Storage System
(20060223)Encrypted keyword search allows a server to perform a search over a set of encrypted documents on behalf of a client without learning the contents of the documents or the words being searched for. Designing a practical ...
