A General Multiple Data Augmentation Based Framework for Training Deep Neural Networks [PDF]

arXiv, 2022
Deep neural networks (DNNs) often rely on massive labelled data for training, which is inaccessible in many applications. Data augmentation (DA) tackles data scarcity by creating new labelled data from available ones. Different DA methods have different mechanisms and therefore using their generated labelled data for DNN training may help improving DNN'

Efficient high-dimensional variational data assimilation with machine-learned reduced-order models [PDF]

arXiv, 2021
Data assimilation (DA) in the geophysical sciences remains the cornerstone of robust forecasts from numerical models. Indeed, DA plays a crucial role in the quality of numerical weather prediction, and is a crucial building block that has allowed dramatic improvements in weather forecasting over the past few decades.

Porous plates at incidence [PDF]

arXiv, 2023
This paper investigates the effect of permeability on two-dimensional rectangular plates at incidences. The flow topology is investigated for Reynolds number ($Re$) values between 30 and 90, and the forces on the plate are discussed for $Re=30$, where the wake is found to be steady for any value of the Darcy number ($Da$) and the flow incidence ...

On Perfectness of Intersection Graph of Ideals of $\mathbb{Z}_n$ [PDF]

Discussiones MathematicaeGeneral Algebra and Applications 37(2017)119-126, 2016
In this paper, we characterize the positive integers $n$ for which intersection graph of ideals of $\mathbb{Z}_n$ is perfect.

Da utilidade da História

Revista de História, 1964
Tenho que confessar de início que não foi sem certo temor que abordei o assunto e escolhi a epígrafe. Pareceu-me mesmo temerário semelhante tema, vivendo eu num tempo em que a utilidade das coisas parece medir-se por um único padrão.

Discriminative and Geometry Aware Unsupervised Domain Adaptation [PDF]

arXiv, 2017
Domain adaptation (DA) aims to generalize a learning model across training and testing data despite the mismatch of their data distributions. In light of a theoretical estimation of upper error bound, we argue in this paper that an effective DA method should 1) search a shared feature subspace where source and target data are not only aligned in terms ...

Reply to "Comment on `Anomalous Reentrant 5/2 Quantum Hall Phase at Moderate Landau-Level-Mixing Strength' " [PDF]

Phys. Rev. Lett. 132, 029602 (2024)
The proposed $\mathcal{A}$ phase and the corresponding trial wavefunction proposed by Das \emph{et al.} (PRL 131, 056202, 2023) for 5/2 state are argued to describe the fractional quantum Hall liquid state rather than a phase separated or stripe or bubble state.

On Leonardo da Vinci's proof of the Theorem of Pythagoras [PDF]

arXiv, 2013
We show that Leonardo da Vinci's well known proof of the Pythagorean theorem is due to Mayer and not to da Vinci.

Online Updating of Word Representations for Part-of-Speech Tagging [PDF]

arXiv, 2016
We propose online unsupervised domain adaptation (DA), which is performed incrementally as data comes in and is applicable when batch DA is not possible. In a part-of-speech (POS) tagging evaluation, we find that online unsupervised DA performs as well as batch DA.

FILOSOFIA DA ANÁLISE DA ESTABILIDADE DA LIQUIDEZ

Revista Catarinense da Ciência Contábil, 2005
A informação foi considerada finalidade de nosso conhecimento, até o período em os pensadores e pesquisadores da contabilidade passaram a raciocinar sobre o conteúdo e o significado dos informes. Nesta busca da razão sobre os estados patrimoniais, surgiu a análise contábil que procura por meio de relações e identidades, o significado da dinâmica ...
