While neural networks produce state-of-the- art performance in several NLP tasks, they generally depend heavily on lexicalized information, which transfer poorly between domains. Previous works have proposed delexicalization as a form of knowledge di
stillation to reduce the dependency on such lexical artifacts. However, a critical unsolved issue that remains is how much delexicalization to apply: a little helps reduce overfitting, but too much discards useful information. We propose Group Learning, a knowledge and model distillation approach for fact verification in which multiple student models have access to different delexicalized views of the data, but are encouraged to learn from each other through pair-wise consistency losses. In several cross-domain experiments between the FEVER and FNC fact verification datasets, we show that our approach learns the best delexicalization strategy for the given training dataset, and outperforms state-of-the-art classifiers that rely on the original data.
The research aimed at studying the impact of the most
important economic and social factors affecting the adoption of new
irrigation techniques، namely water collective management in ALGhab
basin in Syria .The research accomplished by taking a
si
mple random sample of 264 farmers .Because of the nature of
dependent variable which is dichotomous ،(1= adoption of water
collective management،0=otherwise)،The binary logistic regression
was used.
Using the transport kinetic equation for spin density in thin film as 2D Fermi
liquid, the dynamic spin susceptibility is calculated in terms of the Landau
parameters a for thin film. The formula allows to estimate the dispersion relation
of susc
eptibility with arbitrary up to quadric term in wave vector 2 k . The
possibility of experimental determine of Landau's parameters with higher is
discussed and compared with others in this field.
In this research we study the single-particle with particle-rotor model of the
isotopes. The rotational energy of the nucleus related to its
orientation .
This model study the nucleus as a tow parts ; one of them is the core which is
moving in a
collective motion, in addition of the other part of motion which is the single
particle motion outside the core.
The calculation shows that adding the coriolis effect make a better agreement to the
experimental values of the energy than the calculation without the coriolis effect the
research suggestion adding the vibration motion which contributes in the core vibration.
The cooperative learning is teaching techniques that came in the contemporary
educational movement, which researches and studies have shown its positive impact in the
academic achievement of pupils and their contribution to building together social
tools
they have, and gives pupils with a significant impact on their teamwork skills today and in
the future.
The present study aims to investigate the impact of the use of research collective of
cooperative learning in the collection of basic fourth grade in science and health education
pupils strategy, and to achieve the objectives of the research were taken random sample
size / 100/ pupils of pupils fourth grade primary city of Latakia, and dish them
achievement test before start implementing educational program as a test before me, and
after the application of the educational program as a test after me. Search and ended the
following results:
-The existence of differences between the average scores of the experimental group
and the control group average grades at a level of significance (0.05) after the application
of the educational program, to test academic achievement in the dimensional measurement,
and these differences in favor of the experimental group.
-The lack of differences between the average scores of the experimental group males
and females average score of the experimental group at the level of significance (0.05)
after the application of a tutorial on test academic achievement in the dimensional
measurement.
The research aims to identify the reality of the work of tobacco workers union in
Jablah Department, in order to stand on their success in protecting the interests and rights
of members of workers, and to provide the necessary services to them, as
well as to
identify their role in improving the performance of workers in Jablah department.
The researcher has prepared and distributed a questionnaire on the research sample,
which amounted to (77) were distributed among workers (15) in the office of trade union
members and (62) a member of the guild. Data were using SPSS statistical analysis
software.
