Smooth heaps and a dual view of self-adjusting data structures [article]

László Kozma, Thatchaphol Saranurak
2018 arXiv   pre-print
We present a new connection between self-adjusting binary search trees (BSTs) and heaps, two fundamental, extensively studied, and practically relevant families of data structures.  ...  It can be seen as a variation on the popular pairing heap data structure, extending it with a "power-of-two-choices" type of heuristic.  ...  Is there a fundamental, general correspondence between self-adjusting BST and self-adjusting heap data structures?  ...

Structured Penalties for Log-Linear Language Models

Anil Kumar Nelakanti, Cédric Archambeau, Julien Mairal, Francis R. Bach, Guillaume Bouchard
2013 Conference on Empirical Methods in Natural Language Processing  
We account for the sequential structure of natural language using treestructured penalized objectives to avoid overfitting and achieve better generalization.  ...  The complexity of existing algorithms to learn the parameters by maximum likelihood scale linearly in nd, where n is the length of the training corpus and d is the number of observed features.  ...  Projection of a non-negative vector w on the 1 -ball is more involved and requires thresholding 1 p-norm and q -norm are dual to each other if 1 p + 1 q = 1. 2-norm is self-dual while the dual of ∞-norm  ...

Evaluating animations as student aids in learning computer algorithms

Michael D. Byrne, Richard Catrambone, John T. Stasko
1999 Computers & Education  
Across the two studies we used two dierent algorithms Ð depth-®rst search and binomial heaps Ð and used two dierent subject populations Ð students with little or no computer science background and students  ...  However, such a learning improvement was also found when learners made predictions of an algorithm's behavior from static diagrams.  ...  Acknowledgements This research was supported by a grant from the Graphics, Visualization and Usability (GVU) Laboratory of the Georgia Institute of Technology.  ...

Modelling trends in digit preference patterns

Carlo G. Camarda, Paul H. C. Eilers, Jutta Gampe
2016 Journal of the Royal Statistical Society, Series C: Applied Statistics  
Smoothing parameters are selected by the Akaike information criterion. We present a simulation study and apply the model to data on birth weight and on self-reported weight of adults.  ...  A transfer pattern is superimposed on a series of smooth latent distributions and is modulated along a second dimension. Smoothness of the latent distributions is enforced by a roughness penalty.  ...  Acknowledgements The authors thank Dr Stephen A. Roberts who kindly provided the birth weight data from Emmerson and Roberts (2013) .  ...

Implementing sorting in database systems

Goetz Graefe
2006 ACM Computing Surveys  
This survey collects many of these techniques for easy reference by students, researchers, and product developers.  ...  It covers in-memory sorting, disk-based external sorting, and considerations that apply specifically to sorting in database systems.  ...  From this point of view, using a single data structure for many purposes is a good idea.  ...

Regional inequality in human capital formation in Europe, 1790–1880

Ralph Hippe, Joerg Baten
2012 Scandinavian Economic History Review  
By using the age heaping method and a large, new dataset, we approximate the numeracy values in more than 570 regions in Europe between 1790 and 1880.  ...  The results indicate a significant gap in numeracy levels between advanced West and Central European countries and the rest of Europe.  ...  Brezis, Claude Diebolt, Giovanni Federico, Jane Humphries, Pedro Lains, Jaime Reis, Jacob Weisdorf, Ludger Woessmann and participants of the GLOBALEURONET Summer School  ...

Martin Kocher, Konstantin E. Lucks, David Schindler
2018 Social Science Research Network  
Our data indicate a large direct effect of reduced self-control on market overpricing. Low self-control traders report stronger emotions after the market. (  ...  One explanation for overpricing on asset markets is a lack of traders' selfcontrol.  ...  Ozdenoren et al.

Abstract In the long history of rising and persistent unemployment in Europe almost all institutions -employment protection legislation, unions, wages, wage structure, unemployment insurance, etc.  ...  Based on the assertion of the neutrality of money in the medium and long run, the search for causes of European unemployment has shied away from the policy of central banks.  ...  "But if one does not approach the data with a prior view favouring long-run neutrality, one would not leave the data with that posterior.  ...
