🗒️ Last Meeting’s Feedback

David’s Updates

  • David’s been working on hyperparameter tuning for both the graph augmentation and the GCN and GAT models.
  • Results looked good; Zhendong recommended a graph to be created for next week.

Pieter’s Updates

  • First runs with Hierarchical(multi-resolution) model. Added results to scoreboard.
  • Went back to look at coarsening method. New implementation: Small connected components do not get a supernode.

General Discussion

  • Try to use a density plot instead of/in addition to the scatter plot for results and comparison to the Palmes tubes.
  • Provide the final baseline results after Optuna hyperparameter tuning.
  • List all hyperparameters tuned and their final values.

🗒️ Progress

David’s Updates

  • Ran Optuna-based hyperparameter tuning on both GCN and GAT models for 200 trials; added the new scores to the scoreboard.
  • Attempted combined hyperparameter tuning (graph augmentation + model) for 400 trials on both models; results did not improve.
  • Added clear documentation to all code and uploaded it to GitHub.
  • Created the recommended plot from Zhendong.
  • Obtained and finalized all results and code in order to begin writing the thesis.

General Discussion

  • adamoptimizer maybe has 0.010 already implemented? Check how this works.
  • disconnected sets of segments can cause noise, gps inaccuracy can be the cause of the 'disconnectedness'
