Best for

▸Customer segmentation for targeted marketing campaigns using density-based clustering
▸Fraud detection using isolation forests and anomaly scoring thresholds
▸Market basket analysis through association rule mining and pattern discovery
▸Dimensionality reduction for high-dimensional sensor data visualization
▸Exploratory data analysis to discover hidden structure in unlabeled datasets

What you'll get

●Python code implementing HDBSCAN clustering with parameter selection, cluster validation metrics, and visualization using UMAP embeddings
●Comparative analysis of multiple clustering algorithms with silhouette scores, explained variance ratios, and business-interpretable cluster profiles
●Anomaly detection pipeline with Isolation Forest, contamination parameter tuning, and threshold selection based on business constraints

Not designed for ↓

×Predicting specific target values or classifications (that's supervised learning)
×Real-time streaming anomaly detection without batch processing setup
×Generating synthetic data or creating new samples from learned patterns
×Providing business explanations for why clusters formed (requires domain expertise)

Expects

Clean, preprocessed datasets with appropriate scaling and missing value handling, along with clear business objectives for what patterns or structures to discover.

Returns

Cluster assignments, anomaly scores, reduced-dimension embeddings, and diagnostic metrics with recommendations for hyperparameter tuning and algorithm selection.
