Kriging is a geostatistical technique used to predict unknown values at specific locations based on nearby observed data. It is widely used in fields like environmental science, mining, and machine learning for accurate spatial predictions. When applied correctly, kriging can significantly improve prediction accuracy. ✔️ Accurate Predictions: Kriging considers distance and direction of data points for precise estimates. ✔️ Error Minimization: Reduces prediction error by weighting observations based on spatial correlation. ✔️ Uncertainty Assessment: Provides confidence intervals to assess prediction reliability. ✔️ Flexible Methods: Supports ordinary, simple, and universal kriging for different data patterns. ❌ Computational Intensity: Can be demanding for large data sets due to matrix operations. ❌ Overfitting Risk: Complex models might capture noise instead of actual patterns. ❌ Assumption Sensitivity: Relies on assumptions about stationarity and data distribution. ❌ Edge Effects: Predictions near data set edges can be less reliable. The visualization below illustrates simple kriging as the mean and envelope of Brownian random walks passing through the data points.
