🔬 Technical Deep Dive

🧮 Algorithm Choice: Why DBSCAN?

Algorithm	Pros	Cons	Suitability
K-Means	Fast, simple	Requires k, spherical clusters	❌ Poor
Hierarchical	No k needed	Slow, memory intensive	⚠️ Moderate
DBSCAN	Density-based, noise handling	Parameter tuning	✅ Excellent

🎯 DBSCAN Advantages for Movies:

1. 🎭 Natural Groupings: Movies cluster by multiple attributes
2. 🔍 Outlier Detection: Identifies unique/niche movies
3. 📏 No Fixed Clusters: Adapts to data structure
4. 🎲 Arbitrary Shapes: Handles complex movie relationships

⚙️ Hyperparameter Optimization

# Grid Search Results
Best Parameters:
├── eps: 0.5 (optimal neighborhood radius)
├── min_samples: 10 (balanced cluster density)
└── silhouette_score: 0.68 (good cluster quality)

Parameter Analysis:
├── eps=0.2: Too many small clusters (over-segmentation)
├── eps=1.0: Too few large clusters (under-segmentation)
└── eps=0.5: Balanced cluster sizes ✅
