Zero-Shot Relation Extraction (ZRE) is the task of Relation Extraction where
the training and test sets have no shared relation types. This very challenging
domain is a good test of a model's ability to generalize. Previous approaches
to ZRE reframed relation extraction as Question Answering (QA), allowing for
the use ... | http://arxiv.org/abs/2301.09640v2 |
Mixed-choice has long been barred from models of asynchronous communication
since it compromises key properties of communicating finite-state machines.
Session types inherit this restriction, which precludes them from fully
modelling timeouts -- a key programming feature to handle failures. To address
this deficiency, ... | http://arxiv.org/abs/2307.12688v1 |
Quantum circuits of a general quantum gate acting on multiple $d$-level
quantum systems play a prominent role in multi-valued quantum computation. We
first propose a new recursive Cartan decomposition of semi-simple unitary Lie
group $U(3^n)$ (arbitrary $n$-qutrit gate). Note that the decomposition
completely decompose... | http://arxiv.org/abs/2310.11996v1 |
There exists a large literature of construction of convolutional codes with
maximal or near maximal free distance. Much less is known about constructions
of convolutional codes having optimal or near optimal column distances. In this
paper, a new construction of convolutional codes over the binary field with
optimal co... | http://arxiv.org/abs/2305.04693v2 |
In this paper, we build on using the class of f-divergence induced coherent
risk measures for portfolio optimization and derive its necessary optimality
conditions formulated in CAPM format. We derive a new f-Beta similar to the
Standard Betas and also extended it to previous works in Drawdown Betas. The
f-Beta evaluat... | http://arxiv.org/abs/2302.00452v3 |
Large-scale language models have become increasingly challenging and
expensive to train. Among various methods addressing this issue, Pipeline
Parallelism has been widely employed to accommodate massive model weights
within limited GPU memory. This paper introduces Hanayo, a wave-like pipeline
parallelism strategy that... | http://arxiv.org/abs/2308.15762v1 |
To study the overall connectivity in device-to-device networks in cities, we
incorporate a signal-to-interference-plus-noise connectivity model into a
Poisson-Voronoi tessellation model representing the streets of a city. Relays
are located at crossroads (or street intersections), whereas (user) devices are
scattered a... | http://arxiv.org/abs/2309.02137v2 |
Automatic fingerprint recognition systems are the most extensively used
systems for person authentication although they are vulnerable to Presentation
attacks. Artificial artifacts created with the help of various materials are
used to deceive these systems causing a threat to the security of
fingerprint-based applicat... | http://arxiv.org/abs/2303.01465v1 |
Despite its drawbacks, the complete case analysis is commonly used in
regression models with missing covariates. Understanding when implementing
complete cases will lead to consistent parameter estimation is vital before
use. Here, our aim is to demonstrate when a complete case analysis is
appropriate for a nuanced typ... | http://arxiv.org/abs/2303.16119v1 |
In this paper, we propose a feature affinity (FA) assisted knowledge
distillation (KD) method to improve quantization-aware training of deep neural
networks (DNN). The FA loss on intermediate feature maps of DNNs plays the role
of teaching middle steps of a solution to a student instead of only giving
final answers in ... | http://arxiv.org/abs/2302.10899v3 |
The interplay between time-reversal symmetry breaking and strong light-matter
coupling in 2D gases brings intriguing aspects to polariton physics. This
combination can lead to polarization/spin selective light-matter interaction in
the strong coupling regime. In this work, we report such a selective strong
light-matter... | http://arxiv.org/abs/2302.06023v1 |
The hot nucleus $^{162}\mathrm{Dy}$ is investigated using covariant density
functional theory, where the shell-model-like approach treats the pairing
correlation. Lee-Yang's theorem is applied to classify the pairing phase
transition by analyzing the distribution of zeros of the partition function in
the complex temper... | http://arxiv.org/abs/2303.09039v1 |
Recently, Spiking Neural Networks (SNNs), enjoying extreme energy efficiency,
have drawn much research attention on 2D visual recognition and shown gradually
increasing application potential. However, it still remains underexplored
whether SNNs can be generalized to 3D recognition. To this end, we present
Spiking Point... | http://arxiv.org/abs/2310.06232v1 |
We make use of recent estimates for the parameters of the Milky Way's halo
globular clusters and study the influence of the galactic bar on the dynamics
of these clusters by computing their orbits. We use both an axisymmetric and
non-axisymmetric galactic potentials, which include the rotating elongated
bar/bulge struc... | http://arxiv.org/abs/2303.05603v1 |
