Quantum Computing offers a new paradigm for efficient computing and many AI
applications could benefit from its potential boost in performance. However,
the main limitation is the constraint to linear operations that hampers the
representation of complex relationships in data. In this work, we propose an
efficient impl... | http://arxiv.org/abs/2303.05428v1 |
The atmospheric and water turbulence mitigation problems have emerged as
challenging inverse problems in computer vision and optics communities over the
years. However, current methods either rely heavily on the quality of the
training dataset or fail to generalize over various scenarios, such as static
scenes, dynamic... | http://arxiv.org/abs/2308.00622v2 |
We describe two systems currently being developed that use large language
models for the automatized correction of (i) exercises in translating back and
forth between natural language and the languages of propositional logic and
first-order predicate logic and (ii) exercises in writing simple arguments in
natural langu... | http://arxiv.org/abs/2304.06186v3 |
Thermonuclear supernovae, or Type-Ia supernovae (SNeIa), are an essential
tool of cosmology. Precise cosmological constraints are extracted from a Hubble
diagram defined by homogeneous distance indicators, but supernova homogeneity
is not guaranteed. The degree of heterogeneity within the SNeIa parent
population is unk... | http://arxiv.org/abs/2304.01831v2 |
We demonstrate that in situ coherent diffractive imaging (CDI), which
harnesses the coherent interference between a strong and a weak beam
illuminating a static and dynamic structure, can be a very dose-efficient
imaging method. At low doses, in situ CDI can achieve higher resolution than
perfect lenses with the point ... | http://arxiv.org/abs/2306.11283v3 |
A robust summarization system should be able to capture the gist of the
document, regardless of the specific word choices or noise in the input. In
this work, we first explore the summarization models' robustness against
perturbations including word-level synonym substitution and noise. To create
semantic-consistent su... | http://arxiv.org/abs/2306.01090v1 |
We use ideas from quantitative homogenization to show that nonconstant
harmonic functions on the percolation cluster cannot satisfy certain structural
constraints, for example, a Lipschitz bound. These unique-continuation-type
results are false on the full lattice and hence the disorder is utilized in an
essential way. | http://arxiv.org/abs/2303.04736v2 |
In guaranteeing the absence of adversarial examples in an instance's
neighbourhood, certification mechanisms play an important role in demonstrating
neural net robustness. In this paper, we ask if these certifications can
compromise the very models they help to protect? Our new \emph{Certification
Aware Attack} exploit... | http://arxiv.org/abs/2302.04379v4 |
Representation learning is an important step in the machine learning
pipeline. Given the current biological sequencing data volume, learning an
explicit representation is prohibitive due to the dimensionality of the
resulting feature vectors. Kernel-based methods, e.g., SVM, are a proven
efficient and useful alternativ... | http://arxiv.org/abs/2304.00291v1 |
Primordial black holes (PBHs) are known as one of the potential candidates
for dark matter. They are expected to have formed due to the direct
gravitational collapse of density fluctuations in the early Universe.
Therefore, the study of the merger rate of PBHs in modified theories of gravity
can provide more detailed i... | http://arxiv.org/abs/2308.11049v1 |
The Linear-Quadratic Regulation (LQR) problem with unknown system parameters
has been widely studied, but it has remained unclear whether $\tilde{
\mathcal{O}}(\sqrt{T})$ regret, which is the best known dependence on time, can
be achieved almost surely. In this paper, we propose an adaptive LQR controller
with almost s... | http://arxiv.org/abs/2301.05537v3 |
