How to improve the result?

  1. Model hyperparameter tuning
  2. Ensembling different models
  3. Dataset balancing (you can also combine training and validation datasets)
  4. Feature engineering including:
    • Clustering
    • Tasseled cap transformation
    • Spectral indices
    • Using textural features (e.g. SAGA GIS)
    • Reducing spatial resolution
  5. Additional features:
    • Radar data from Sentinel 1
    • Normalized digital surface model (nDSM)
    • Panchromatic band (15 m)
    • Satellite scene from another date(s)
  6. Post-processing:
    • Modal filter
    • Sieve filter

It is recommended to use a machine learning framework, e.g. tidymodels, mlr3 or scikit-learn. Check out also programming language agnostic frameworks such as mlpack and H2O.
