practice, few applications of blockchain are closed i.e. do not interact with
the world outside the bl... | http://arxiv.org/abs/2302.01764v1 |
Explainable Artificial Intelligence (XAI) techniques are frequently required
by users in many AI systems with the goal of understanding complex models,
their associated predictions, and gaining trust. While suitable for some
specific tasks during development, their adoption by organisations to enhance
trust in machine ... | http://arxiv.org/abs/2302.11577v2 |
SiRGraF Integrated Tool for Coronal dynaMics (SITCoM) is based on Simple
Radial Gradient Filter (SiRGraF) used to filter the radial gradient in the
white-light coronagraph images and bring out dynamic structures. SITCoM has
been developed in Python and integrated with SunPy and can be installed by
users with the comman... | http://arxiv.org/abs/2308.04647v1 |
In recent years, blockchain technology has introduced decentralized finance
(DeFi) as an alternative to traditional financial systems. DeFi aims to create
a transparent and efficient financial ecosystem using smart contracts and
emerging decentralized applications. However, the growing popularity of DeFi
has made it a ... | http://arxiv.org/abs/2308.15992v3 |
We show that for $q\in (0,1),$ the $C^{*}$-algebra $SU_{q}(3)$ is isomorphic
a rank $2$ graph $C^{*}$-algebra (in the sense of Pask and Kumjian). This graph
is derived by passing the to the limit $q\to 0$ for a set of generators of
$SU_{q}(3)$. Moreover, the isomorphism can be taken to be
$\mathbb{T}^{2}$-equivariant w... | http://arxiv.org/abs/2307.12878v2 |
To segment a signal into blocks to be analyzed, few-shot keyword spotting
(KWS) systems often utilize a sliding window of fixed size. Because of the
varying lengths of different keywords or their spoken instances, choosing the
right window size is a problem: A window should be long enough to contain all
necessary infor... | http://arxiv.org/abs/2305.10816v3 |
Recent advancements in measurement techniques have resulted in an increasing
amount of data on neural activities recorded in parallel, revealing largely
heterogeneous correlation patterns across neurons. Yet, the mechanistic origin
of this heterogeneity is largely unknown because existing theoretical
approaches linking... | http://arxiv.org/abs/2308.00421v3 |
Under the expected total reward criterion, the optimal value of a
finite-horizon Markov decision process can be determined by solving the Bellman
equations. The equations were extended by D. J. White to processes with vector
rewards in 1982. Using a counterexample, we show that the assumptions
underlying this extension... | http://arxiv.org/abs/2306.16937v3 |
High power density systems require efficient cooling to maintain their
thermal performance. Despite this, as systems get larger and more complex,
human practice and insight may not suffice to determine the desired thermal
management system designs. To this end, a framework for automatic architecture
exploration is pres... | http://arxiv.org/abs/2310.15500v1 |
We present a simple picture of the training process of joint embedding
self-supervised learning methods. We find that these methods learn their
high-dimensional embeddings one dimension at a time in a sequence of discrete,
well-separated steps. We arrive at this conclusion via the study of a
linearized model of Barlow ... | http://arxiv.org/abs/2303.15438v2 |
This is a brief introduction to link homology theories that categorify
Reshetikhin--Turaev $\mathsf{SL}(N)$-quantum link invariants. A recently
discovered surprising connection between finite state automata and Boolean
TQFTs in dimension one is explained as a warm-up. | http://arxiv.org/abs/2309.00708v2 |
This paper explores a hierarchical prompting mechanism for the hierarchical
image classification (HIC) task. Different from prior HIC methods, our
hierarchical prompting is the first to explicitly inject ancestor-class
information as a tokenized hint that benefits the descendant-class
discrimination. We think it well i... | http://arxiv.org/abs/2304.06385v5 |
This paper contains a method to prove the existence of smooth curves in
positive characteristic whose Jacobians have unusual Newton polygon. Using this
method, I give a new proof that there exist supersingular curves of genus $4$
for every prime $p$. More generally, for every prime $p$ and every $g \geq 4$,
I prove tha... | http://arxiv.org/abs/2306.11080v3 |
Numerical simulation for climate modeling resolving all important scales is a
computationally taxing process. Therefore, to circumvent this issue a low
resolution simulation is performed, which is subsequently corrected for bias
using reanalyzed data (ERA5), known as nudging correction. The existing
implementation for ... | http://arxiv.org/abs/2302.03173v1 |
