Transformers have emerged as a prominent model framework for audio tagging
(AT), boasting state-of-the-art (SOTA) performance on the widely-used Audioset
dataset. However, their impressive performance often comes at the cost of high
memory ...

Topological insulators have been studied intensively over the last decades.
Earlier research focused on Hermitian Hamiltonians, but recently, peculiar and
interesting properties were found by introducing non-Hermiticity. In this work,
we ap...

We developed a statistical inference method applicable to a broad range of
generalized linear models (GLMs) in high-dimensional settings, where the number
of unknown coefficients scales proportionally with the sample size. Although a
pionee...

The Feigin--Frenkel theorem states that, over the complex numbers, the centre
of the universal affine vertex algebra at the critical level is an infinite
rank polynomial algebra. The first author and W.~Wang observed that in positive

We prove an equivariant version of the classical Menger-Nobeling theorem
regarding topological embeddings: Whenever a group G acts on a
finite-dimensional compact metric space X, a generic continuous equivariant
function from X into $...

Numerical Analysis
Deflation techniques are typically used to shift isolated clusters of small
eigenvalues in order to obtain a tighter distribution and a smaller condition
number. Such changes induce a positive effect in the convergence behavior of

Smart contracts are contractual agreements between participants of a
blockchain, who cannot implicitly trust one another. They are software programs
that run on top of a blockchain, and we may need to change them from time to

Despite recent significant progress, Multi-Object Tracking (MOT) faces
limitations such as reliance on prior knowledge and predefined categories and
struggles with unseen objects. To address these issues, Generic Multiple Object
Tracking (G...

High Energy Astrophysical Phenomena
Analysing the available data relative to the anisotropies of the
ultra-high-energy cosmic rays (UHECR) at intermediate angular scales, we
examine to what extent they can be used to constrain the origin of these
particles, and what could be ...
Flexible sensitivity analysis for causal inference in observational
studies subject to unmeasured confounding
May 28, 2023

Statistics
Methodology
Causal inference with observational studies often suffers from unmeasured
confounding, yielding biased estimators based on the unconfoundedness
assumption. Sensitivity analysis assesses how the causal conclusions change
with respect to diff...
