Medios geo-sociales como proxy de los datos meteorológicos para el monitoreo de inundaciones

Medios geo-sociales como proxy de los datos meteorológicos para el monitoreo de inundaciones Geo-social media as a proxy for meteorological data for flood monitoring. Camilo Ernesto Restrepo Estrada Affiliation: PhD student Universidad de Sao Paulo Abstract: Flooding is one of the most impacting type of disaster worldwide in terms of human, economic and social losses. In cases in which authoritative data is scarce or lacking for some...

Oaxaca-Blinder Type Counterfactual Decomposition Methods for Duration Outcomes

Oaxaca-Blinder Type Counterfactual Decomposition Methods for Duration Outcomes. Andrés Felipe García-Suaza Abstract: Existing inference procedures to perform counterfactual decomposition of the difference between distributional features, applicable when data is fully observed, are not suitable for censored outcomes. This may explain the lack of decomposition exercises for variables related to duration outcomes, typically observed...

Normalization by Evaluation

Normalization by Evaluation. Andreas Abel. Abstract: In computer systems that manipulate syntactic objects, like computeralgebra systems, compilers, and theorem provers, we find algorithms that check whether two expressions are equal. Some expression classes admit normal forms. For objects of these classes, equality can be decided by checking that the expressions under consideration have the same normal form. Conversion to normal form...
