We introduce Prototype Generation, a stricter and more robust form of feature
visualisation for model-agnostic, data-independent interpretability of image
classification models. We demonstrate its ability to generate inputs that
result in natural activation paths, countering previous claims that feature
visualisation a... | http://arxiv.org/abs/2309.17144v1 |
Network Intrusion Detection System (NIDS) is an essential tool in securing
cyberspace from a variety of security risks and unknown cyberattacks. A number
of solutions have been implemented for Machine Learning (ML), and Deep Learning
(DL) based NIDS. However, all these solutions are vulnerable to adversarial
attacks, i... | http://arxiv.org/abs/2308.00077v1 |
We consider the statistical properties of eigenstates of the time-evolution
operator in chaotic many-body quantum systems. Our focus is on correlations
between eigenstates that are specific to spatially extended systems and that
characterise entanglement dynamics and operator spreading. In order to isolate
these aspect... | http://arxiv.org/abs/2309.12982v2 |
This paper introduces the Point Cloud Network (PCN) architecture, a novel
implementation of linear layers in deep learning networks, and provides
empirical evidence to advocate for its preference over the Multilayer
Perceptron (MLP) in linear layers. We train several models, including the
original AlexNet, using both M... | http://arxiv.org/abs/2309.12996v1 |
Isospectral reduction is an important tool for network/matrix analysis as it
reduces the dimension of a matrix/network while preserving all its eigenvalues
and eigenvectors. The main contribution of this manuscript is a proposed
algorithmic scheme to approximate the stationary measure of a stochastic matrix
based on is... | http://arxiv.org/abs/2308.00063v2 |
We present a new model of two electrically coupled optomechanical cavities.
This model is based on the recently presented [Physical Review A \textbf{103}
(2021) 043509]. We found that coupling two optomechanical cavities via Coulomb
force leads to cross-Kerr interactions between those cavities. We show that
such system... | http://arxiv.org/abs/2309.10159v1 |
The application of artificial intelligence to simulate air-to-air combat
scenarios is attracting increasing attention. To date the high-dimensional
state and action spaces, the high complexity of situation information (such as
imperfect and filtered information, stochasticity, incomplete knowledge about
mission targets... | http://arxiv.org/abs/2309.11247v1 |
Stablecoins, which are primarily intended to function as a global reserve of
value are insubstantial in their design and present many failure points. The
primary mechanism to enable these coins to hold on to a fixed value is by
backing them with collateral. Fiat collateralized stablecoins require users to
trust a centr... | http://arxiv.org/abs/2309.11521v1 |
Recent work has empirically shown that deep neural networks latch on to the
Fourier statistics of training data and show increased sensitivity to
Fourier-basis directions in the input. Understanding and modifying this
Fourier-sensitivity of computer vision models may help improve their
robustness. Hence, in this paper ... | http://arxiv.org/abs/2301.13514v1 |
The Fermi function $F(Z,E)$ accounts for QED corrections to beta decays that
are enhanced at either small electron velocity $\beta$ or large nuclear charge
$Z$. For precision applications, the Fermi function must be combined with other
radiative corrections and with scale- and scheme-dependent hadronic matrix
elements.... | http://arxiv.org/abs/2309.07343v2 |
We study the question of whether submodular functions of random variables
satisfying various notions of negative dependence satisfy Chernoff-like
concentration inequalities. We prove such a concentration inequality for the
lower tail when the random variables satisfy negative association or negative
regression, partial... | http://arxiv.org/abs/2309.05554v2 |
End-to-end learning has become a popular method for joint transmitter and
receiver optimization in optical communication systems. Such approach may
require a differentiable channel model, thus hindering the optimization of
links based on directly modulated lasers (DMLs). This is due to the DML
behavior in the large-sig... | http://arxiv.org/abs/2309.15747v2 |
We present a singular perturbation theory applicable to systems with hybrid
boundary layer systems and hybrid reduced systems {with} jumps from the
boundary layer manifold. First, we prove practical attractivity of an adequate
attractor set for small enough tuning parameters and sufficiently long time
between almost al... | http://arxiv.org/abs/2303.18238v1 |
The relevance of optimal transport methods to machine learning has long been
hindered by two salient limitations. First, the $O(n^3)$ computational cost of
standard sample-based solvers (when used on batches of $n$ samples) is
prohibitive. Second, the mass conservation constraint makes OT solvers too
rigid in practice:... | http://arxiv.org/abs/2305.19727v1 |
