A High Stego-image Quality Steganographic Scheme with Reversibility and High Payload Using Multiple Embedding Strategy
(2011-06-13)
Tian’s method is a breakthrough reversible data embedding scheme with high embedding capacity measured by bits per pixel (bpp) and good visual quality measured by peak signal-to-noise ratio (PSNR). However, the embedding ...
A lossless data embedding technique by joint neighboring coding
(2011-06-14)
Information hiding methods are currently exploited by many researchers for various applications. Proposing an efficient and feasible information hiding method is valuable. This paper presents a new reversible information ...
Fast node embeddings: learning ego-centric representations
(Universidade Federal de Minas GeraisUFMG, 2018-02-26)
Representation learning is one of the foundations of Deep Learning and allowed important improvements on several Machine Learning tasks, such as Neural Machine Translation, Question Answering and Speech Recognition. Recent ...
Assessing Lexical-Semantic Regularities in Portuguese Word Embeddings
Models of word embeddings are often assessed when solving syntactic and semantic analogies. Among the latter, we are interested in relations that one would find in lexical-semantic knowledge bases like WordNet, also covered ...
Pricing options embedded in debentures with credit risk
(2015)
In this article, we develop a strategy to simultaneously extract a yield curve and price call options embedded in debentures subject to credit risk. The implementation is based on a combination of two methods: term structure ...
A mixture theory based method for three-dimensional modeling of reinforced concrete members with embedded crack finite elements
(Techno-Press, 2008-12)
The paper presents a methodology to model three-dimensional reinforced concrete members by means of embedded discontinuity elements based on the Continuum Strong Discontinuous Approach (CSDA). Mixture theory concepts are ...
