Active learning for regression by inverse distance weighting

open access: yesInformation Sciences, 2023
This paper proposes an active learning (AL) algorithm to solve regression problems based on inverse-distance weighting functions for selecting the feature vectors to query. The algorithm has the following features: (i) supports both pool-based and population-based sampling; (ii) is not tailored to a particular class of predictors; (iii) can handle ...

Comparative study of interpolation methods for mapping soil pH in the apple orchards of Murree, Pakistan

open access: yesSoil & Environment, 2017
Soil pH is considered as a core indicator for nutrient bioavailability. Prevailing alkaline pH due to calcareousness in Pakistan is considered as one of the limiting factor for nutrient availability to plants.
