Shapley effects are a particularly interpretable approach to assessing how a
function depends on its various inputs. The existing literature contains
various estimators for this class of sensitivity indices in the context of
nonparametric r...

Efficient automatic segmentation of multi-level (i.e. main and branch)
pulmonary arteries (PA) in CTPA images plays a significant role in clinical
applications. However, most existing methods concentrate only on main PA or
branch PA segment...

A well known extension of Einstein General Relativity is the addition of an
R2-term, which is free of ghost excitations and in the linearized framework,
reduces Einstein General Relativity and an additional higher derivative scalar.

Information Retrieval
Entity Set Expansion (ESE) is a critical task aiming at expanding entities of
the target semantic class described by seed entities. Most existing ESE methods
are retrieval-based frameworks that need to extract contextual features of

A noetherian form is an abstract self-dual framework suitable for
establishing homomorphism theorems (such as the isomorphism theorems and
homological diagram lemmas) for non-abelian, as well as abelian, group-like
structures. It can be see...
