On the generalized eigenvalue method for energies and matrix elements in lattice field theory
(INT SCHOOL ADVANCED STUDIES, 2009)
We discuss the generalized eigenvalue problem for computing energies and matrix elements in lattice gauge theory, including effective theories such as HQET. It is analyzed how the extracted effective energies and matrix ...
Konishi OPE coefficient at the five loop order
(2018-11-01)
We use the method of asymptotic expansions to study the OPE limit of a fourpoint function of protected operators in N= 4 SYM. We use a new method for evaluating the resulting propagator-type integrals and then extract the ...
All five-loop planar four-point functions of half-BPS operators in N= 4 SYM
(2018-11-01)
We obtain all planar four-point correlators of half-BPS operators in N= 4 SYM up to five loops. The ansatz for the integrand is fixed partially by imposing lightcone OPE relations between different correlators. We then fix ...
MathFeature: feature extraction package for DNA, RNA and protein sequences based on mathematical descriptors
(2022-01-17)
One of the main challenges in applying machine learning algorithms to biological sequence data is how to numerically represent a sequence in a numeric input vector. Feature extraction techniques capable of extracting ...
A tutorial review on entropy-based handcrafted feature extraction for information fusion
(2018-05-01)
Entropy (H) is the main subject of this article, concisely written to serve as a tutorial introducing two feature extraction (FE) methods for usage in digital signal processing (DSP) and pattern recognition (PR). The theory, ...
Extracting OPE coefficient of Konishi at four loops
(2017-03-01)
In this short note we compute the OPE coefficient of two 20′ operators and the Konishi operator. To this end, we use the OPE decomposition of a four point function of four 20′ operators and the method of asymptotic expansions ...
ZCR-aided neurocomputing: A study with applications
(2016-08-01)
This paper covers a particular area of interest in pattern recognition and knowledge-based systems (PRKbS), being intended for both young researchers and academic professionals who are looking for a polished and refined ...
An artificial immune system based on information theory for keyword extraction from text documents
(Universidad Nacional de Colombia -Sede Medellín, 2007)
This paper presents a model for keyword extraction, extending the basic concepts commonly used in this task, in order to get a formal background that allows determining the importance of the keywords to the documents. The ...
Effective theory for neutral resonances and a statistical dissection of the ATLAS diboson excess
(Springer, 2015-12-15)
We classify the complete set of dimension-5 operators relevant for the resonant production of a singlet of spin 0 or 2 linearly coupled to the Standard Model (SM). We compute the decay width of such states as a function ...
