Sampling Approach Matters: Active Learning for Robotic Language Acquisition
Ordering the selection of training data using active learning can lead to improvements in learning efficiently from smaller corpora. We present an exploration of active learning approaches applied to three grounded language ... -
SAT-based Compressive Sensing
(2019-03-06)We propose to reduce the original well-posed problem of compressive sensing to weighted-MAX-SAT. Compressive sensing is a novel randomized data acquisition approach that linearly samples sparse or compressible signals at ... -
SAT: an SVM-based Automated Trust Management System for Mobile Ad-hoc Networks
(IEEE, 2011-11-01)Mobile Ad-hoc Networks (MANETs) are extremely vulnerable to a variety of misbehaviors because of their basic features, including lack of communication infrastructure, short transmission range, and dynamic network topology. ... -
Satellite data fusion of multiple observed XCO2 using compressive sensing
(SPIE, 2020-04-22)When it entered into the era of big data, Earth observing systems developed into a new stage, namely characterized by low cost, multi-national, multi-sensor and multi-modal with varying spatial and spectral resolutions ... -
Scalability Analysis of Blockchain on a Serverless Cloud
(IEEE, 2019-12-10)While adopting Blockchain technologies to automate their enterprise functionality, organizations are recognizing the challenges of scalability and manual configuration that the state of art present. Scalability of Hyperledger ... -
Scalable Noisy Image Restoration using Quantum Markov Random Field
(2018-01-01)We propose an algorithm for binary image denoising, which uses a Markovian Random Field based energy optimization approach to remove Gaussian and salt and pepper noise. It is a two-stage algorithm. In the first stage, the ... -
Scantegrity II Municipal Election at Takoma Park: The First E2E Binding Governmental Election with Ballot Privacy
(2009-11-03)On November 3, 2009, voters in Takoma Park, Maryland, cast ballots for the mayor and city council members using the Scantegrity II voting system—the first time any end-to-end (E2E) voting system with ballot privacy has ... -
Scantegrity III: Automatic Trustworthy Receipts, Highlighting Over/Under Votes, and Full Voter Verifiability
(2017)Building on lessons learned from the November 2009 Scantegrity II election in Takoma Park, MD, we propose improvements to the Scantegrity II voting system that (1) automatically print trustworthy receipts for easier on-line ... -
Schema-Free Structured Querying of DBpedia Data
(ACM, 2012-08-11)We need better ways to query large linked data collections such as DBpedia. Using the SPARQL query language requires not only mastering its syntax but also understanding the RDF data model, large ontology vocabularies and ... -
Search Engines for Semantic Web Knowledge
(2006-05-16)Web search engines such as Google have made people "smarter" by making knowledge readily available whenever we need to look up a fact, evaluate options or learn about a topic. The Semantic Web effort aims to make such ... -
Search on the Semantic Web
(2005-09-01)The Semantic Web provides a way to encode information and knowledge on web pages in a form that is easier for computers to understand and process. This article discusses the issues underlying the discovery, indexing and ... -
Searching for Common Sense: Populating Cyc from the Web
(Association for the Advancement of Artificial Intelligence (AAAI), 2005-07)The Cyc project is predicated on the idea that effective machine learning depends on having a core of knowledge that provides a context for novel learned information – what is known informally as “common sense.” Over the ... -
Searching for Selfie in TLS 1.3 with the Cryptographic Protocol Shapes Analyzer
(Springer, 2021-11-19)TLS 1.3 was developed in conjunction with several formal analyses and proofs of its security properties. However, in 2019, researchers Drucker and Gueron discovered a reflection attack, they named Selfie, against the ... -
Second harmonic generation (SHG) from resonant GaAs gratings
(OSA Publishing, 2011-05-22)We study SHG in nonlinear (NL), GaAs gratings. We find large enhancement of conversion efficiency when the pump field excites the guided mode resonances (GMRs) [1] of the grating. Under these circumstances the spectrum ... -
Second harmonic generation from metallo-dielectric multilayered structures in the plasmonic regime
We present a theoretical study on second harmonic generation from metallo-dielectric multilayered structures in the plasmonic regime. In particular we analyze the behavior of structures made of Ag (silver) and MgF₂ ... -
Second harmonic generation in one-dimensional photonic crystals: optimization procedure
(SPIE, 2004-09-15)We present a new concept for efficient second harmonic generation that is based upon the interference of counter-propagating waves in multilayer structures. We show that phase matching and quasi phase matching are not ... -
Second Space: A Generative Model For The Blogosphere
(AAAI, 2008-03-31)Web graphs have been very useful in the structural and statistical analysis of the web. Various models have been proposed to simulate web graphs that generate degree distributions similar to the web. Real world blog networks ... -
Second-harmonic generation from a positive-negative index material heterostructure
(American Physical Society (APS), 2005-12-21)Resonant cavities have been widely used in the past to enhance material, nonlinear response. Traditional mirrors include metallic films and distributed Bragg reflectors. In this paper we propose negative index material ... -
Secrecy Outage of Cooperative Relay Network With and Without Eavesdropper’s Direct Link
(IEEE, 2017-10-23)In this paper, a source communicates to the destination with the cooperation of a relay, in the presence of an eavesdropper. All the links undergo Rayleigh fading and perfect decoding at the relays is not considered. The ... -
Secrecy Outage Performance of Cooperative Relay Network With Diversity Combining
(IEEE, 2017-12-01)In this paper, the secrecy outage probability of threshold-based decode-and-forward (DF) cooperative relay network is evaluated. Unlike other works to date, we assume combining of direct and relayed signals both at the ...
