Improving Skip-Gram based Graph Embeddings via Centrality-Weighted Sampling
(Cornell University, 2019)
Network embedding techniques inspired by word2vec represent an e ective unsuper- vised relational learning model. Commonly, by means of a Skip-Gram procedure, these techniques learn low dimensional vector representations ...

Generative Adversarial Networks Selection Approach for Extremely Imbalanced Fault Diagnosis of Reciprocating Machinery
(IEEE Computer Society, 2019)
At present, countless approaches to fault diagnosis in reciprocating machines have been proposed, all considering that the available machinery dataset is in equal proportions for all conditions. However, when the application ...

The Potosí principle: religious prosociality fosters selforganization of larger commnities under extreme natural and economic conditions
(Oxford Academic, 2012)
We show how in colonial Potosı´ (present-day Bolivia) social and political stabil-ity was achieved through the self-organization of society through the repetition of religious rituals. Our analysis shows that the population ...

Institutions and Cultural Diversity: Effects of Democratic and Propaganda Processes on Local Convergence and Global Diversity
(Public Library of Science, 2016)
In a connected world where people influence each other, what can cause a globalized monoculture, and which measures help to preserve the coexistence of cultures? Previous research has shown that factors such as homophily, ...

Automatic feature extraction of time-series applied to fault severity assessment of helical gearbox in stationary and non-stationary speed operation
(Elsevier, 2017)
Signals captured in rotating machines to obtain the status of their components can be considered as a source of massive information. In current methods based on artificial intelligence to fault severity assessment, features ...

BML model on non-orientable surfaces
(Elsevier, 2010)
Two-dimensional Biham Middleton Levine traffic model on a N N square lattice embedded on a Klein bottle and a projective plane is investigated by computer simulations. The behavior of the model with these boundary ...

Fault diagnosis of spur gearbox based on random forest and wavelet packet decomposition
(Springer, 2015)
This paper addresses the development of a random forest classifier for the multi-class fault diagnosis in spur gearboxes. The vibration signal’s condition parameters are first extracted by applying the wavelet packet ...
