The proliferation of data collection technologies often results in large sets with many observations and variables. In practice, highly relevant engineered features are groups predictors that share a common regression coefficient (i.e., the group affect response only via their collective sum), where unknown advance must be discovered from data. We propose an algorithm called tree (CTR) to disco...

However, feelings grief are clinically diagnosed part depression only if symptoms persist at least two weeks. Eventually, can last several weeks, months, or years.

Surface roughness parameters, such as roughness length and displacement height, impact the estimation of surface moisture, and the frontal areas of buildings and trees are two components that contribute to surface roughness in urban areas. Research on tree frontal area has not been conducted in urban areas before, and we hope to fill that gap in the literature with this study by using Terrestri...
