Learning Faithful Representations of Causal Graphs [PDF]

open access: yesProceedings of the 59th Annual Meeting of the Association for Computational Linguistics and the 11th International Joint Conference on Natural Language Processing (Volume 1: Long Papers), 2021
Learning contextual text embeddings that represent causal graphs has been useful in improving the performance of downstream tasks like causal treatment effect estimation. However, existing causal embeddings which are trained to predict direct causal links, fail to capture other indirect causal links of the graph, thus leading to spurious correlations ...

Faithful representations with topographic maps [PDF]

open access: yesNeural Networks, 1999
Topographic map algorithms that are aimed at building "faithful representations" also yield maps that transfer the maximum amount of information available about the distribution from which they receive input. The weight density (magnification factor) of these maps is proportional to the input density, or the neurons of these maps have an equal ...

Isometric Representations of Totally Ordered Semigroups [PDF]

open access: yes, 2012
Let S be a subsemigroup of an abelian torsion-free group G. If S is a positive cone of G, then all C*-algebras generated by faithful isometrical non-unitary representations of S are canonically isomorphic. Proved by Murphy, this statement generalized the

The faithful triangular representations of Kaloujnine$p$-groups over a $p$-element field

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2013
The faithful triangular representations of finite Kaloujnine $p$-groups is studied. Images of generators of those groups are described. Infinite-dimensional representation of the direct limit of Kaloujnine $p$-groups is regarded.

Abelian varieties with isogenous reductions

open access: yesComptes Rendus. Mathématique, 2021
Let $A_1$ and $A_2$ be abelian varieties over a number field $K$. We prove that if there exists a non-trivial morphism of abelian varieties between reductions of $A_1$ and $A_2$ at a sufficiently high percentage of primes, then there exists a non-trivial

Spectral Representations of Neutron-Star Equations of State [PDF]

open access: yes, 2010
Methods are developed for constructing spectral representations of cold (barotropic) neutron-star equations of state. These representations are faithful in the sense that every physical equation of state has a representation of this type, and conversely ...

Complex Hyperbolic Structures on Disc Bundles over Surfaces [PDF]

open access: yes, 2011
We study complex hyperbolic disc bundles over closed orientable surfaces that arise from discrete and faithful representations H_n->PU(2,1), where H_n is the fundamental group of the orbifold S^2(2,...,2) and thus contains a surface group as a subgroup ...

Groups with faithful irreducible projective unitary representations [PDF]

open access: yesForum Mathematicum, 2011
For a countable group G and a multiplier c on G with values in the circle, we study the property of G having a unitary projective c-representation which is both irreducible and projectively faithful. We show that this property is equivalent to G being the quotient of an appropriate group by its centre.

Faithful Representations of Lie Groups II [PDF]

open access: yesNagoya Mathematical Journal, 1950
The present paper is a continuation of Part I. In the introduction of Part I we have explained our main problems and sketched their results. In the present part we shall proceed to give complete proofs of them.

On cospectrality of gain graphs

open access: yesSpecial Matrices, 2022
We define GG-cospectrality of two GG-gain graphs (Γ,ψ)\left(\Gamma ,\psi ) and (Γ′,ψ′)\left(\Gamma ^{\prime} ,\psi ^{\prime} ), proving that it is a switching isomorphism invariant.
