account uncertainties from both experimental data and the dynamical modeling of
the experiment. We demonstrate that ignoring dynamical model uncertainty may
lead to predictions that are inconsistent with the uncertainty present in
quantum data. A ... | http://arxiv.org/abs/2308.12552v1 |
As a popular paradigm of distributed learning, personalized federated
learning (PFL) allows personalized models to improve generalization ability and
robustness by utilizing knowledge from all distributed clients. Most existing
PFL algorithms tackle personalization in a model-centric way, such as
personalized layer par... | http://arxiv.org/abs/2303.08678v1 |
Let $C$ and $D$ be smooth, proper and geometrically integral curves over a
finite field $F$. Any morphism from $D$ to $C$ induces a morphism of their
\'etale fundamental groups. The anabelian philosophy proposed by Grothendieck
suggests that, when $C$ has genus at least $2$, all open homomorphisms between
the \'etale f... | http://arxiv.org/abs/2306.04844v3 |
We present CoTe2 as a new type-II Dirac semimetal supporting Lorentz symmetry
violating Dirac fermions in the vicinity of the Fermi energy. By combining
first principle ab-initio calculations with experimental angle-resolved
photo-emission spectroscopy results, we show the CoTe2 hosts a pair of type-II
Dirac fermions a... | http://arxiv.org/abs/2301.11550v1 |
For infinite action contextual bandits, smoothed regret and reduction to
regression results in state-of-the-art online performance with computational
cost independent of the action set: unfortunately, the resulting data exhaust
does not have well-defined importance-weights. This frustrates the execution of
downstream d... | http://arxiv.org/abs/2302.08551v2 |
Members of different political groups not only disagree about issues but also
dislike and distrust each other. While social media can amplify this emotional
divide -- called affective polarization by political scientists -- there is a
lack of agreement on its strength and prevalence. We measure affective
polarization o... | http://arxiv.org/abs/2310.18553v2 |
Recent progress in artificial intelligence has renewed interest in building
machines that learn like animals. Almost all of the work comparing learning
across biological and artificial systems comes from studies where animals and
machines received different training data, obscuring whether differences
between animals a... | http://arxiv.org/abs/2306.05582v1 |
Large Language Models (LLMs) are transforming the landscape of mobile
intelligence. Federated Learning (FL), a method to preserve user data privacy,
is often employed in fine-tuning LLMs to downstream mobile tasks, an approach
known as FedLLM. Though recent efforts have addressed the network issue induced
by the vast m... | http://arxiv.org/abs/2308.13894v2 |
Entities and events are crucial to natural language reasoning and common in
procedural texts. Existing work has focused either exclusively on entity state
tracking (e.g., whether a pan is hot) or on event reasoning (e.g., whether one
would burn themselves by touching the pan), while these two tasks are often
causally r... | http://arxiv.org/abs/2301.10896v3 |
New chat AI applications like ChatGPT offer an advanced understanding of
question context and memory across multi-step tasks, such that experiments can
test its deductive reasoning. This paper proposes a multi-role and multi-step
challenge, where ChatGPT plays the classic twenty-questions game but
innovatively switches... | http://arxiv.org/abs/2301.01743v1 |
Recent work has shown that Large Language Models (LLMs) can unintentionally
leak sensitive information present in their training data. In this paper, we
present Model Perturbations (MoPe), a new method to identify with high
confidence if a given text is in the training data of a pre-trained language
model, given white-... | http://arxiv.org/abs/2310.14369v1 |
In this paper, we study one-dimensional hyperbolic Anderson models (HAM)
driven by space-time pure-jump L\'evy white noise in a finite-variance setting.
Motivated by recent active research on limit theorems for stochastic partial
differential equations driven by Gaussian noises, we present the first study in
this L\'ev... | http://arxiv.org/abs/2302.14178v4 |
