🏷️ Labels: HDBSCAN, UMAP, Clustering, Data Visualization, Parameter Tuning
📂 Project: Dev
⭐ Priority: MEDIUM

The session aimed to enhance clustering techniques using HDBSCAN and UMAP to explore latent data structures and improve clustering results.

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.

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.

Finalize the implementation of the hyperparameter explorer for HDBSCAN and test its effectiveness in real-world datasets.
