One approach for interpreting black-box machine learning models is to find a
global approximation of the model using simple interpretable functions, which
is called a metamodel (a model of the model). Approximating the black-box with
a metamodel can be used to 1) estimate instance-wise feature importance; 2)
understand... | http://arxiv.org/abs/2302.04791v1 |
The goal of this paper is to develop methodology for the systematic analysis
of asymptotic statistical properties of data driven DRO formulations based on
their corresponding non-DRO counterparts. We illustrate our approach in various
settings, including both phi-divergence and Wasserstein uncertainty sets.
Different t... | http://arxiv.org/abs/2303.14867v1 |
While transformer-based pre-trained language models (PLMs) have dominated a
number of NLP applications, these models are heavy to deploy and expensive to
use. Therefore, effectively compressing large-scale PLMs becomes an
increasingly important problem. Quantization, which represents high-precision
tensors with low-bit... | http://arxiv.org/abs/2306.00014v1 |
We consider the kinetics of the imperfect narrow escape problem, i.e. the
time it takes for a particle diffusing in a confined medium of generic shape to
reach and to be adsorbed by a small, imperfectly reactive patch embedded in the
boundary of the domain, in two or three dimensions. Imperfect reactivity is
modeled by... | http://arxiv.org/abs/2305.06135v1 |
Existing research has shown that a multilingual pre-trained language model
fine-tuned with one (source) language also performs well on downstream tasks
for non-source languages, even though no fine-tuning is done on these
languages. However, there is a clear gap between the performance of the source
language and that o... | http://arxiv.org/abs/2305.11449v1 |
We introduce a new method which resolves the problem of regularity and
compactness of entropy solutions for nonlinear degenerate parabolic equations
under non-degeneracy conditions on the sphere. In particular, we address a
problem of regularity of entropy solutions to homogeneous (autonomous)
degenerate parabolic PDEs... | http://arxiv.org/abs/2309.00691v1 |
In Online Continual Learning (OCL) a learning system receives a stream of
data and sequentially performs prediction and training steps. Important
challenges in OCL are concerned with automatic adaptation to the particular
non-stationary structure of the data, and with quantification of predictive
uncertainty. Motivated... | http://arxiv.org/abs/2306.08448v1 |
Following the discovery of radio pulsars at the position of Fermi-LAT
unassociated sources by the TRAPUM group, we conduct Swift-XRT observations of
six of those 4FGL sources to determine if any pulsar-like X-ray sources are
present and to confirm the reported detection of an X-ray counterpart via
eROSITA at 4FGL J1803... | http://arxiv.org/abs/2307.07452v1 |
Let $(\lambda_f(n))_{n\geq 1}$ be the Hecke eigenvalues of either a
holomorphic Hecke eigencuspform or a Hecke-Maass cusp form $f$. We prove that,
for any fixed $\eta>0$, under the Ramanujan-Petersson conjecture for $\rm GL_2$
Maass forms, the Rankin-Selberg coefficients $(\lambda_f(n)^2)_{n\geq 1}$ admit
a level of di... | http://arxiv.org/abs/2304.08231v2 |
Out-of-Distribution (OoD) detection has developed substantially in the past
few years, with available methods approaching, and in a few cases achieving,
perfect data separation on standard benchmarks. These results generally involve
large or complex models, pretraining, exposure to OoD examples or extra
hyperparameter ... | http://arxiv.org/abs/2308.10973v1 |
Complex dexterous manipulations require switching between prehensile and
non-prehensile grasps, and sliding and pivoting the object against the
environment. This paper presents a manipulation planner that is able to reason
about diverse changes of contacts to discover such plans. It implements a
hybrid approach that pe... | http://arxiv.org/abs/2306.06465v1 |
We study the latitudinal distribution and temporal evolution of the sunspot
penumbra-umbra ratio (q) for the even and odd Solar Cycles 12-24 of RGO sunspot
groups, SC21-SC24 of Debrecen sunspot groups and Kodaikanal sunspot dataset for
SC16-SC24. We find that RGO even (odd) Cycles have q-values 5.20 (4.75),
Kodaikanal ... | http://arxiv.org/abs/2305.10757v1 |
This article argues that frontier artificial intelligence (AI) developers
need an internal audit function. First, it describes the role of internal audit
in corporate governance: internal audit evaluates the adequacy and
effectiveness of a company's risk management, control, and governance
processes. It is organization... | http://arxiv.org/abs/2305.17038v2 |
This work introduces Neural Chronos Ordinary Differential Equations (Neural
CODE), a deep neural network architecture that fits a continuous-time ODE
dynamics for predicting the chronology of a system both forward and backward in
time. To train the model, we solve the ODE as an initial value problem and a
final value p... | http://arxiv.org/abs/2307.01023v1 |
