# Brainy Neural API Surface Design
|
||||
|
||||
## 🎯 **Clean API Hierarchy**
|
||||
|
||||
### **Main Class Shortcuts (Simple & Common)**
|
||||
```typescript
|
||||
// High-level shortcuts on BrainyData - most common operations
|
||||
brain.similar(a, b, options?) // ✅ Keep - very common
|
||||
brain.clusters(items?, options?) // ✅ Keep - very common
|
||||
brain.related(id, options?) // ✅ Keep - common (like neighbors but simpler name)
|
||||
|
||||
// Remove/deprecate confusing shortcuts
|
||||
brain.visualize(options?) // ❌ Remove - too specialized for main class
|
||||
```
|
||||
|
||||
### **Neural Namespace (Full Featured)**
|
||||
```typescript
|
||||
// Core semantic operations
|
||||
brain.neural.similar(a, b, options?) // Comprehensive similarity
|
||||
brain.neural.clusters(items?, options?) // Smart clustering with auto-routing
|
||||
brain.neural.neighbors(id, options?) // K-nearest neighbors (full featured)
|
||||
brain.neural.hierarchy(id, options?) // Semantic hierarchy building
|
||||
brain.neural.outliers(options?) // Anomaly detection
|
||||
brain.neural.visualize(options?) // Visualization data generation
|
||||
|
||||
// Advanced clustering methods
|
||||
brain.neural.clusterByDomain(field, options?) // Domain-aware clustering
|
||||
brain.neural.clusterByTime(field, windows, options?) // Temporal clustering
|
||||
brain.neural.clusterStream(options?) // Streaming/real-time clustering
|
||||
brain.neural.updateClusters(items, options?) // Incremental clustering
|
||||
|
||||
// Utility methods
|
||||
brain.neural.getPerformanceMetrics(operation?) // Performance monitoring
|
||||
brain.neural.clearCaches() // Cache management
|
||||
brain.neural.getCacheStats() // Cache statistics
|
||||
```
|
||||
|
||||
## 🔒 **Private Methods (Internal Implementation)**
|
||||
|
||||
### **Should NOT be exposed publicly:**
|
||||
```typescript
|
||||
// These are implementation details:
|
||||
brain.neural._clusterFast() // ❌ Private - use clusters() with algorithm: 'hierarchical'
|
||||
brain.neural._clusterLarge() // ❌ Private - use clusters() with algorithm: 'sample'
|
||||
brain.neural._performHierarchicalClustering() // ❌ Private - internal routing
|
||||
brain.neural._performKMeansClustering() // ❌ Private - internal routing
|
||||
brain.neural._performDBSCANClustering() // ❌ Private - internal routing
|
||||
brain.neural._performSampledClustering() // ❌ Private - internal routing
|
||||
brain.neural._routeClusteringAlgorithm() // ❌ Private - internal routing
|
||||
brain.neural._similarityById() // ❌ Private - internal routing
|
||||
brain.neural._similarityByVector() // ❌ Private - internal routing
|
||||
brain.neural._similarityByText() // ❌ Private - internal routing
|
||||
brain.neural._isId() // ❌ Private - utility
|
||||
brain.neural._isVector() // ❌ Private - utility
|
||||
brain.neural._convertToVector() // ❌ Private - utility
|
||||
brain.neural._cacheResult() // ❌ Private - caching
|
||||
brain.neural._trackPerformance() // ❌ Private - monitoring
|
||||
```
|
||||
|
||||
### **Current Issues in brain-cloud explorer:**
|
||||
```typescript
|
||||
// ❌ BAD: Accessing private implementation details
|
||||
brain.neural.clusterFast({ maxClusters: count, level: 2 })
|
||||
|
||||
// ✅ GOOD: Use public API with proper options
|
||||
brain.neural.clusters({ algorithm: 'hierarchical', maxClusters: count, level: 2 })
|
||||
```
|
||||
|
||||
## 📊 **API Consistency Fixes**
|
||||
|
||||
### **Method Naming Standardization:**
|
||||
```typescript
|
||||
// ✅ CONSISTENT: Pick one naming pattern and stick to it
|
||||
brain.neural.similar() // Main method name
|
||||
brain.similar() // Shortcut matches
|
||||
|
||||
// ❌ INCONSISTENT: Don't mix these
|
||||
brain.neural.similarity() // Different from shortcut
|
||||
brain.similar()
|
||||
```
|
||||
|
||||
### **Parameter Patterns:**
|
||||
```typescript
|
||||
// ✅ CONSISTENT: Always (data, options?) pattern
|
||||
brain.neural.similar(a, b, options?)
|
||||
brain.neural.clusters(items?, options?)
|
||||
brain.neural.neighbors(id, options?)
|
||||
brain.neural.hierarchy(id, options?)
|
||||
|
||||
// Options should be objects with clear properties
|
||||
interface ClusteringOptions {
|
||||
algorithm?: 'auto' | 'hierarchical' | 'kmeans' | 'dbscan'
|
||||
maxClusters?: number
|
||||
threshold?: number
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
### **Return Type Consistency:**
|
||||
```typescript
|
||||
// ✅ CONSISTENT: All clustering methods return SemanticCluster[]
|
||||
brain.neural.clusters() → Promise<SemanticCluster[]>
|
||||
brain.neural.clusterByDomain() → Promise<DomainCluster[]> // extends SemanticCluster
|
||||
brain.neural.clusterByTime() → Promise<TemporalCluster[]> // extends SemanticCluster
|
||||
|
||||
// ✅ CONSISTENT: All similarity methods return number or SimilarityResult
|
||||
brain.neural.similar() → Promise<number | SimilarityResult>
|
||||
brain.similar() → Promise<number> // Shortcut always returns simple number
|
||||
```
|
||||
|
||||
## 🚀 **Performance & Intelligence Routing**
|
||||
|
||||
### **Auto-Algorithm Selection:**
|
||||
```typescript
|
||||
// Smart routing based on data size and characteristics
|
||||
brain.neural.clusters() // Auto-selects:
|
||||
// < 100 items → hierarchical (fast, accurate)
|
||||
// < 1000 items → k-means (balanced)
|
||||
// > 1000 items → sampling (scalable)
|
||||
|
||||
// Manual override available
|
||||
brain.neural.clusters({ algorithm: 'hierarchical' }) // Force specific algorithm
|
||||
```
|
||||
|
||||
### **Caching Strategy:**
|
||||
```typescript
|
||||
// Intelligent caching with LRU eviction
|
||||
brain.neural.similar('id1', 'id2') // First call: compute & cache
|
||||
brain.neural.similar('id1', 'id2') // Second call: instant cache hit
|
||||
|
||||
// Cache management
|
||||
brain.neural.clearCaches() // Manual cache clear
|
||||
brain.neural.getCacheStats() // Monitor cache performance
|
||||
```
|
||||
|
||||
## 📚 **Documentation Structure**
|
||||
|
||||
### **Main Documentation Sections:**
|
||||
1. **Quick Start**: Simple examples using shortcuts (`brain.similar()`, `brain.clusters()`)
|
||||
2. **Neural API Guide**: Comprehensive examples using `brain.neural.*`
|
||||
3. **Advanced Clustering**: Domain, temporal, streaming clustering
|
||||
4. **Performance**: Caching, algorithm selection, monitoring
|
||||
5. **API Reference**: Complete method documentation
|
||||
|
||||
### **Example Progression:**
|
||||
```typescript
|
||||
// 1. BEGINNER: Simple shortcuts
|
||||
const similarity = await brain.similar('text1', 'text2')
|
||||
const clusters = await brain.clusters()
|
||||
|
||||
// 2. INTERMEDIATE: Neural API with options
|
||||
const detailed = await brain.neural.similar('id1', 'id2', { detailed: true })
|
||||
const customClusters = await brain.neural.clusters({ algorithm: 'hierarchical', maxClusters: 5 })
|
||||
|
||||
// 3. ADVANCED: Specialized clustering
|
||||
const domainClusters = await brain.neural.clusterByDomain('category')
|
||||
const streamingClusters = brain.neural.clusterStream({ batchSize: 50 })
|
||||
```
|
||||
|
||||

## 🎯 **API Surface Summary**
|
||||
|
||||
### **✅ PUBLIC API** (What users should use):
|
||||
- **Main shortcuts**: `brain.similar()`, `brain.clusters()`, `brain.related()`
|
||||
- **Neural namespace**: `brain.neural.similar()`, `brain.neural.clusters()`, etc.
|
||||
- **Advanced features**: Domain clustering, temporal clustering, streaming
|
||||
- **Utilities**: Performance metrics, cache management
|
||||
|
||||
### **❌ PRIVATE IMPLEMENTATION** (Internal only):
|
||||
- **Algorithm implementations**: `_performKMeansClustering()`, etc.
|
||||
- **Routing logic**: `_routeClusteringAlgorithm()`, etc.
|
||||
- **Utility methods**: `_isId()`, `_convertToVector()`, etc.
|
||||
- **Caching internals**: `_cacheResult()`, `_trackPerformance()`, etc.
|
||||
|
||||
### **⚠️ DEPRECATED** (Should be removed/hidden):
|
||||
- **brain.neural.clusterFast()** → Use `brain.neural.clusters({ algorithm: 'hierarchical' })`
|
||||
- **brain.neural.clusterLarge()** → Use `brain.neural.clusters({ algorithm: 'sample' })`
|
||||
- **brain.neural.similarity()** → Use `brain.neural.similar()` (pick one name)
|
||||
- **brain.visualize()** → Too specialized for main class, use `brain.neural.visualize()`
