# Autonomous Implementation Guide for Dream-Inspired Memory Consolidation

## Overview

This document provides a comprehensive guide for implementing the [Dream-Inspired Memory Consolidation System](./dream-inspired-memory-consolidation.md) as a fully autonomous system that runs without external AI dependencies.

## Key Insight

**The dream-inspired memory consolidation system can run almost entirely on autopilot** by leveraging the embeddings already generated during memory storage. These embeddings, combined with mathematical algorithms and rule-based logic, enable autonomous operation without external AI.

## Autonomous Components Analysis

### ✅ 100% Autonomous: Exponential Decay Scoring

Pure mathematical calculations requiring zero AI intervention:

```python
import math
from datetime import datetime

class AutonomousDecayCalculator:
    def __init__(self, retention_periods):
        self.retention_periods = retention_periods
    
    def calculate_relevance(self, memory):
        """Calculate memory relevance using pure math."""
        age = (datetime.now() - memory.created_at).total_seconds() / 86400  # days
        base_score = memory.importance_score
        
        retention_period = self.retention_periods.get(
            memory.memory_type, 
            self.retention_periods['default']
        )
        
        # Exponential decay
        decay_factor = math.exp(-age / retention_period)
        
        # Connection boost (pure counting)
        connection_boost = 1 + (0.1 * len(memory.connections))
        
        return base_score * decay_factor * connection_boost
```

### ✅ 100% Autonomous: Creative Association System

Uses existing embeddings with vector mathematics:

```python
import numpy as np
from itertools import combinations
import random

class AutonomousAssociationEngine:
    def __init__(self, similarity_threshold=(0.3, 0.7)):
        self.min_similarity, self.max_similarity = similarity_threshold
    
    def find_associations(self, memories):
        """Find creative connections using only embeddings."""
        # Limit pairs to prevent combinatorial explosion
        max_pairs = min(100, len(memories) * (len(memories) - 1) // 2)
        
        if len(memories) < 2:
            return []
        
        # Random sampling of pairs
        all_pairs = list(combinations(range(len(memories)), 2))
        sampled_pairs = random.sample(
            all_pairs, 
            min(max_pairs, len(all_pairs))
        )
        
        associations = []
        for i, j in sampled_pairs:
            # Cosine similarity using existing embeddings
            similarity = self._cosine_similarity(
                memories[i].embedding,
                memories[j].embedding
            )
            
            # Check if in creative "sweet spot"
            if self.min_similarity < similarity < self.max_similarity:
                associations.append({
                    'memory_1': memories[i].hash,
                    'memory_2': memories[j].hash,
                    'similarity': similarity,
                    'discovered_at': datetime.now()
                })
        
        return associations
    
    def _cosine_similarity(self, vec1, vec2):
        """Calculate cosine similarity between two vectors."""
        vec1 = np.array(vec1)
        vec2 = np.array(vec2)
        
        dot_product = np.dot(vec1, vec2)
        norm_product = np.linalg.norm(vec1) * np.linalg.norm(vec2)
        
        return dot_product / norm_product if norm_product > 0 else 0
```

### ✅ 100% Autonomous: Controlled Forgetting

Rule-based logic with no AI required:

```python
class AutonomousPruningEngine:
    def __init__(self, config):
        self.relevance_threshold = config['relevance_threshold']
        self.access_threshold_days = config['access_threshold_days']
        self.protected_tags = {'important', 'critical', 'reference'}
    
    def identify_forgettable_memories(self, memories):
        """Identify memories for archival using rules."""
        forgettable = []
        
        for memory in memories:
            # Skip protected memories
            if memory.tags & self.protected_tags:
                continue
            
            # Check relevance score
            if memory.relevance_score < self.relevance_threshold:
                # Check connections
                if len(memory.connections) == 0:
                    # Check last access
                    days_since_access = (
                        datetime.now() - memory.last_accessed
                    ).days
                    
                    if days_since_access > self.access_threshold_days:
                        forgettable.append(memory)
        
        return forgettable
```

### 🔧 90% Autonomous: Semantic Compression

Uses statistical methods instead of generative AI:

```python
from collections import Counter
from sklearn.cluster import AgglomerativeClustering
import numpy as np

class AutonomousCompressionEngine:
    def __init__(self):
        self.keyword_extractor = TFIDFKeywordExtractor()
    
    def compress_cluster(self, memories):
        """Compress memories without using generative AI."""
        if not memories:
            return None
        
        # 1. Find centroid (most representative memory)
        embeddings = np.array([m.embedding for m in memories])
        centroid = np.mean(embeddings, axis=0)
        
        # Calculate distances to centroid
        distances = [
            np.linalg.norm(centroid - emb) 
            for emb in embeddings
        ]
        representative_idx = np.argmin(distances)
        representative_memory = memories[representative_idx]
        
        # 2. Extract keywords using TF-IDF
        all_content = ' '.join([m.content for m in memories])
        keywords = self.keyword_extractor.extract(all_content, top_k=20)
        
        # 3. Aggregate metadata
        all_tags = set()
        for memory in memories:
            all_tags.update(memory.tags)
        
        # 4. Create structured summary (not prose)
        compressed = {
            "type": "compressed_cluster",
            "representative_content": representative_memory.content,
            "representative_hash": representative_memory.hash,
            "cluster_size": len(memories),
            "keywords": keywords,
            "common_tags": list(all_tags),
            "temporal_range": {
                "start": min(m.created_at for m in memories),
                "end": max(m.created_at for m in memories)
            },
            "centroid_embedding": centroid.tolist(),
            "member_hashes": [m.hash for m in memories]
        }
        
        return compressed

class TFIDFKeywordExtractor:
    """Simple TF-IDF based keyword extraction."""
    
    def extract(self, text, top_k=10):
        # Simple word frequency for demonstration
        # In practice, use sklearn's TfidfVectorizer
        words = text.lower().split()
        word_freq = Counter(words)
        
        # Filter common words (simple stopword removal)
        stopwords = {'the', 'a', 'an', 'and', 'or', 'but', 'in', 'on', 'at'}
        keywords = [
            (word, count) 
            for word, count in word_freq.most_common(top_k * 2)
            if word not in stopwords and len(word) > 3
        ]
        
        return keywords[:top_k]
```

## Implementation Checklist

- [ ] Install required Python packages (numpy, scikit-learn, apscheduler)
- [ ] Configure retention periods for your use case
- [ ] Set up clustering thresholds based on your embedding model
- [ ] Configure scheduling based on your memory volume
- [ ] Test each component independently
- [ ] Monitor initial runs and adjust thresholds
- [ ] Set up logging and monitoring
- [ ] Create backup strategy for archived memories

## Conclusion

The autonomous implementation proves that sophisticated memory consolidation doesn't require external AI. By leveraging existing embeddings and mathematical algorithms, we achieve a system that mimics biological memory processes while maintaining complete independence, privacy, and cost-effectiveness.

This approach transforms the dream-inspired concept into a practical, deployable system that can run indefinitely without human intervention or external dependencies - a true "set it and forget it" solution for memory management.
