Description
Session Goal
The session aimed to enhance clustering techniques using HDBSCAN and UMAP to explore latent data structures and improve clustering results.
Key Activities
- Parameter Tuning for HDBSCAN: Adjusted parameters like ‘min_cluster_size’, ‘min_samples’, and ‘cluster_selection_epsilon’ to optimize cluster detection.
- UMAP Projections: Explored multiple UMAP projections to visualize latent structures, emphasizing the use of more than two dimensions.
- Visualization and Conflict Resolution: Addressed size conflicts in UMAP visualizations and iterated through axis pairs to enhance data representation.
- Clustering Function Development: Implemented a customizable HDBSCAN function for time-based data, including parameter tuning insights.
- Exploratory Analysis: Designed loops to analyze cluster results, reporting on cluster sizes and noise to compare configurations.
- Hyperparameter Explorer Design: Proposed a multivariate hyperparameter explorer for HDBSCAN to optimize clustering outcomes.
Achievements
- Successfully adjusted HDBSCAN parameters and explored UMAP projections, improving clustering insights.
- Resolved visualization conflicts and enhanced data representation through iterative plotting.
- Developed a robust framework for exploring clustering configurations and optimizing HDBSCAN parameters.
Pending Tasks
- Finalize the implementation of the hyperparameter explorer for HDBSCAN and test its effectiveness in real-world datasets.
