Fast Large-Scale Reionization Simulations [PDF]

open access: yes, 2008
We present an efficient method to generate large simulations of the Epoch of Reionization (EoR) without the need for a full 3-dimensional radiative transfer code.

Large-scale Complex IT Systems [PDF]

open access: yes, 2011
This paper explores the issues around the construction of large-scale complex systems which are built as 'systems of systems' and suggests that there are fundamental reasons, derived from the inherent complexity in these systems, why our current software

Intelligent Design of Hairpin Filters Based on Artificial Neural Network and Proximal Policy Optimization

open access: yesApplied Sciences, 2023
Microstrip filters are widely used in high-frequency circuit design for signal frequency selection. However, designing these filters often requires extensive trial and error to achieve the desired performance metrics, leading to significant time costs ...

Large-scale games in large-scale systems [PDF]

open access: yesProceedings of the 5th International ICST Conference on Performance Evaluation Methodologies and Tools, 2011
Many real-world problems modeled by stochastic games have huge state and/or action spaces, leading to the well-known curse of dimensionality. The complexity of the analysis of large-scale systems is dramatically reduced by exploiting mean field limit and dynamical system viewpoints. Under regularity assumptions and specific time-scaling techniques, the

Large Scale Homing in Honeybees [PDF]

open access: yes, 2015
Honeybee foragers frequently fly several kilometres to and from vital resources, and communicate those locations to their nest mates by a symbolic dance language.

Forming characteristics analysis of variable-process alternated overlapping strategy based on contour description for laser melting deposition

open access: yesJournal of Materials Research and Technology, 2023
To predict the geometric characteristics and improve the forming quality and macro-micro defects of multi-track overlapping cladding layer effectively, the experimental research of laser melting deposition single-track Co-based alloy on 42CrMo substrate ...

Large-Scale Correlation Screening [PDF]

open access: yesJournal of the American Statistical Association, 2011
This paper treats the problem of screening for variables with high correlations in high dimensional data in which there can be many fewer samples than variables. We focus on threshold-based correlation screening methods for three related applications: screening for variables with large correlations within a single treatment (autocorrelation screening);

VoxCeleb: A Large-Scale Speaker Identification Dataset [PDF]

open access: yesInterspeech, 2017
Most existing datasets for speaker identification contain samples obtained under quite constrained conditions, and are usually hand-annotated, hence limited in size.

Parameter-efficient fine-tuning of large-scale pre-trained language models

open access: yesNature Machine Intelligence, 2023
With the prevalence of pre-trained language models (PLMs) and the pre-training–fine-tuning paradigm, it has been continuously shown that larger models tend to yield better performance. However, as PLMs scale up, fine-tuning and storing all the parameters
