Multiple Regression

Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Integrating Remote Sensing with Species Distribution Models; Mapping Tamarisk Invasions Using the Software for Assisted Habitat Modeling (SAHM)

Published on: October 11, 2016

  • Developed biomass-yield estimation models using four machine learning techniques and ensemble learning.
  • Employed Shapley additive explanation (SHAP) for feature contribution analysis.

    • Main Results:

    • Spectral-texture features were most effective for biomass estimation.
    • Three-dimensional (3D) spectral-textural-structural features were optimal for yield estimation.
    • Ensemble learning with these features significantly improved estimation accuracy (biomass R²=0.72, yield R²=0.68).
    • The model demonstrated stable predictions across variety-density interactions.

    Conclusions:

    • The proposed framework provides an accurate and generalizable approach for rapeseed biomass and yield estimation.
    • This method offers valuable insights for precision harvesting applications.
    • The study highlights the effectiveness of integrating multidimensional features and ensemble learning.
