Environment

Python 3.9.0
Packages: See requirements.txt

Overview

Core implementation:

• magicLAT.py
  • Implementation of graph-based interpolation method MAGIC-LAT.
• metrics.py
  • Implementation of Delta-E and other performance metrics.
• utils.py
  • Implementation of realistic sub-sampling protocol.

Helper methods:

• readLAT.py
  • Parses the SpatialLAT text file from CARTO system.
• readMesh.py
  • Parses the MESHData .mesh file from CARTO system.
• quLATiHelper.py
  • Interfaces with the GPMI (quLATi) package.

Other:

• const.py
  • Defines directory and file paths for data.
• params.py
  • Grid search for optimal regularization parameters.
• plot_params.py
  • Plots results generated by params.py.
• plot_varied_m.py
  • Plots results generated by test_varied_m.py.
• test.py
  • Tests GPR, GPMI, and MAGIC-LAT interpolation on a single map and generates visual results.
• test_anomalies.py
  • Plots LAT observations sequentially to view/identify anomalous points.
• test_repeated.py
  • Tests GPR, GPMI, and MAGIC-LAT on a single map with random repetition and saves performance metric results.
• test_varied_m.py
  • Tests GPR, GPMI, and MAGIC-LAT on a single map with random repetition and varied numbers of input LAT observations, and saves the performance metric results.
