\[IV(S,a)=-\sum_{v\in values(a)}{\frac{|x\in S|value(x,a)=v|}{|S|}*log_2(\frac{|x\in S|value(x,a)=v|}{|S|})} \] 这个公式怎么理解呢? S就是数据集样本,\(|S|\)就是样本数量; a是某一个特征,比方说Outlook或者是Wind,然后\(v\in values(a)\)就是v就是a这个特征...

En general, estos modelos consideran distintas maneras de cómo trabajar la variable respuesta, por ejemplo la exponenciación de la respuesta usando la transformación log-gamma28. Regresión Adaptativa Multivariada (MARS) MARS es una metodología propuesta por Friedman29 en el año 1991, que ...
Which are the winner and loser shrub species in a warming tundra and what are their trait combinations? Tall plants with wind-dispersed seeds are usually more competitive as they have facilitated seed dispersal and shade shorter plants51. We expect winners to be mainly tall shrubs, given that ...

Suppose that the surface wind is blowing from the north along the Oregon coast. a. Predict the direction of Ekman transport of surface waters. b. Would you expect coastal upwelling or down swelling? What happens to ocean waters as the atmospheric concentration of CO2 ...
Finally, as the main findings, the wind speed is the main contribution to the erosive variables and the intensity of the rainfall, as well as the frequency in log meteorological data, are also significant factors affecting the three erosive variables. 展开 ...
