Chain-of-Thought (CoT) plays a crucial role in reasoning for math problem
solving. We conduct a comprehensive examination of methods for designing CoT,
comparing conventional natural language CoT with various program CoTs,
including the self-describing program, the comment-describing program, and the
non-describing pro... | http://arxiv.org/abs/2309.11054v2 |
Large training sets have become a cornerstone of machine learning and are the
foundation for recent advances in language modeling and multimodal learning.
While data curation for pre-training is often still ad-hoc, one common paradigm
is to first collect a massive pool of data from the Web and then filter this
candidat... | http://arxiv.org/abs/2309.17425v3 |
We introduce and study a class of betweenness algebras-Boolean algebras with
binary operators, closely related to ternary frames with a betweenness
relation. From various axioms for betweenness, we chose those that are most
common, which makes our work applicable to a wide range of betweenness
structures studied in the... | http://arxiv.org/abs/2309.00159v1 |
This letter investigates relationships between iterated filtering algorithms
based on statistical linearization, such as the iterated unscented Kalman
filter (IUKF), and filtering algorithms based on quasi-Newton (QN) methods,
such as the QN iterated extended Kalman filter (QN-IEKF). Firstly, it is shown
that the IUKF ... | http://arxiv.org/abs/2309.07636v2 |
Advances in Large Language Models (LLMs) have led to remarkable capabilities,
yet their inner mechanisms remain largely unknown. To understand these models,
we need to unravel the functions of individual neurons and their contribution
to the network. This paper introduces a novel automated approach designed to
scale in... | http://arxiv.org/abs/2305.19911v1 |
In this paper, we use a probabilistic model to estimate the number of
uncorrelated features in a large dataset. Our model allows for both pairwise
feature correlation (collinearity) and interdependency of multiple features
(multicollinearity) and we use the probabilistic method to obtain upper and
lower bounds of the s... | http://arxiv.org/abs/2309.13657v1 |
Single-shot auctions are commonly used as a means to sell goods, for example
when selling ad space or allocating radio frequencies, however devising
mechanisms for auctions with multiple bidders and multiple items can be
complicated. It has been shown that neural networks can be used to approximate
optimal mechanisms w... | http://arxiv.org/abs/2303.00116v1 |
We discuss recent progress towards extending the Helac framework to the
calculation of two-loop amplitudes. A general algorithm for the automated
computation of two-loop integrands is described. The algorithm covers all the
steps of the computation, from the generation of loop topologies up to the
construction of recur... | http://arxiv.org/abs/2309.14886v4 |
Dexterous manipulation tasks involving contact-rich interactions pose a
significant challenge for both model-based control systems and imitation
learning algorithms. The complexity arises from the need for multi-fingered
robotic hands to dynamically establish and break contacts, balance
non-prehensile forces, and contr... | http://arxiv.org/abs/2309.03322v1 |
Programmers and researchers are increasingly developing surrogates of
programs, models of a subset of the observable behavior of a given program, to
solve a variety of software development challenges. Programmers train
surrogates from measurements of the behavior of a program on a dataset of input
examples. A key chall... | http://arxiv.org/abs/2309.11726v1 |
Multi-Access Point Coordination (MAPC) is becoming the cornerstone of the
IEEE 802.11bn amendment, alias Wi-Fi 8. Among the MAPC features, Coordinated
Spatial Reuse (C-SR) stands as one of the most appealing due to its capability
to orchestrate simultaneous access point transmissions at a low implementation
complexity.... | http://arxiv.org/abs/2309.09169v2 |
Magnetic nanomaterials can be used in the construction of devices for
information processing and memory storage. For this purpose, they have to enjoy
two contradictory properties, from one side being able of keeping for long time
magnetization frozen, hence information stored, and from the other side
allowing for quick... | http://arxiv.org/abs/2309.15568v1 |
