Loess - Wikipedia The uppermost loess, the Peoria Loess, in which the modern soil has developed, accumulated during the late Wisconsin Stage Animal remains include terrestrial gastropods and mastodons
LOESS局部加权回归 - 知乎 算法思想类似 K N N 算法，只不过在LOESS中，通过调节参数 k 来控制估计结果的平滑性。 而这实际上实在平衡结果的偏移性和方差，提高 k 值可能导致更高的偏移性，而降低 k 值则有可能使得方差更大。 可以说，LOESS是一种对整个数据集进行的非参数估计方法。
Loess genesis and worldwide distribution - ScienceDirect Loess formation generally involves the four main stages of production, deflation, transportation, and deposition of loess particles Traditionally, loesses are classified as glacial, desert, or other types based only on source area characteristics without taking into account provenance and transportation
Alternative vegetation states on the Loess Plateau and . . . - PNAS Recognizing the Loess Plateau as the world’s largest afforestation area, we explored vegetation states across a large-scale survey to reassess precipitation thresholds of afforestation We identified a forest maintenance threshold of 350 mm precipitation, above which forest, open woodland, and treeless states coexist A minimal model consistent with observations suggests that forest
Loess - National Geographic Society In some parts of the world, windblown dust and silt blanket the land This layer of fine, mineral-rich material is called loess
