reval

reval implements stability-based relative clustering validation to identify robust clustering solutions by evaluating the replicability of clustering partitions on unseen data subsets using supervised learning.

Key Features:

• Stability-based relative validation: Evaluates clustering solutions by measuring stability of partitions across resampled or held-out data subsets.
• Supervised learning assessment: Uses classification algorithms to assess how well cluster labels replicate on unseen data.
• Support for multiple clustering algorithms: Integrates with different clustering methods to compare their relative stability.
• Support for multiple classification algorithms: Allows use of various classifiers to automate labeling and evaluate replicability.
• Automation of labeling: Generates cluster labels via supervised models to quantify partition consistency.
• Focus on replicability: Quantifies the ability of clustering partitions to reproduce results on unseen subsets.

Scientific Applications:

• Optimal clustering selection: Selecting the most robust clustering solution in unsupervised learning contexts.
• Comparative evaluation of clustering mechanisms: Assessing and comparing stability across different clustering algorithms and parameterizations.
• Validation in bioinformatics analyses: Validating cluster replicability and robustness for biological datasets with varying distributions.

Methodology:

Stability-based relative clustering validation implemented via supervised learning to evaluate replicability of clustering partitions on unseen data subsets, with support for multiple clustering and classification algorithms.
