Quick Start

Basic Usage

python
from dlm.response import ReplyChainSystem, ResponseConfig

# Create system with default config
system = ReplyChainSystem(verbose=True)

# Process a conversation
conversation = [
    {"prompt": "What is machine learning?", "response": "ML is a subset of AI..."},
    {"prompt": "How does it work?", "response": "It learns from data patterns..."}
]

system.process_conversations(conversation)

# Get conversation metrics
metrics = system.get_conversation_metrics()
print(f"User patterns: {metrics['user_patterns']}")

Using Custom Configuration

python
from dlm.response import ReplyChainSystem, ResponseConfig

# Create performance-optimized configuration
config = ResponseConfig.create_performance_optimized()

# Create system with custom config
system = ReplyChainSystem(verbose=True)

# Manually configure
system.chain_tree.max_active_chains = config.archival.max_active_chains
system.propagate_context(learning_rate=config.ircp.default_learning_rate)

With Embedding Provider

python
from dlm.response import ReplyChainSystem, SimpleEmbeddingProvider

# Wrap your embedding function
embedding_provider = SimpleEmbeddingProvider(
    embedding_function=your_embedding_model.encode,
    cache_capacity=512,
    enable_caching=True
)

# Create system with embedding provider
system = ReplyChainSystem(
    verbose=True,
    embedding_provider=embedding_provider
)

# Context archival and similarity will use cached embeddings
history = system.prepare_conversation_history(
    prompt="Tell me about neural networks",
    use_context_archival=True
)

Key Features

1. I-RCP (Inverse-Ring Context Propagation)

The module implements a dual-ring architecture:
- Forward Ring: Assistant messages with coordinates (x, y, z)
- Inverse Ring: User responses with coordinates (x', y', z')

python
# Propagate context with adaptive steps
result = system.propagate_context(
    adaptive=True,
    convergence_threshold=1e-4,
    learning_rate=0.1
)

print(f"Converged after {result['steps_taken']} steps")

2. Context Archival System

Automatically manage context size by archiving irrelevant chains:

python
# Archive chains with low relevance
archived_count = system.chain_tree.archive_chains_by_relevance(
    current_focus="neural network architectures",
    min_relevance=0.6
)

# Restore relevant archived chains
restored_count = system.chain_tree.restore_chains_by_query(
    query="transformer models",
    similarity_threshold=0.7
)

# Get archive statistics
stats = system.chain_tree.get_archive_statistics()
print(f"Total archived: {stats['total_archived_chains']}")

3. Context Reordering

Optimize context order for relevance:

python
# Reorder chains using hybrid strategy
system.chain_tree.reorder_chains(
    strategy="hybrid",  # Options: relevance, hybrid, attention, hierarchical
    focus_text="How do transformers work?",
    preserve_pairs=True,
    max_position_shift=3
)

4. User Pattern Analysis

Analyze user behavior and adapt responses:

python
# Analyze user patterns
patterns = system.analyze_user_patterns()
print(f"Intent depth: {patterns['average_intent_depth']}")
print(f"Categories: {patterns['user_categories']}")

# Get adaptation recommendations
recommendations = system.recommend_content_adaptation()
print(f"Content depth: {recommendations['content_depth']}")
print(f"Tone: {recommendations['tone']}")

# Adapt response to user patterns
adapted_response = system.adapt_response_to_user_patterns(
    "Here's a detailed explanation of transformers..."
)

Performance Optimization

Embedding Cache

python
from dlm.response import EmbeddingCache

cache = EmbeddingCache(capacity=256, ttl=3600)

# Cache is automatic with SimpleEmbeddingProvider
provider = SimpleEmbeddingProvider(
    embedding_function=model.encode,
    cache_capacity=512,
    enable_caching=True
)

# Get cache statistics
stats = provider.get_cache_stats()
print(f"Cache hit rate: {stats['hit_rate']:.2%}")

Batch Processing

python
# Similarity computation is automatically batched
similarities = provider.compute_similarities_batch(
    query_text="What is AI?",
    texts=["AI is...", "Machine learning...", "Deep learning..."]
)

Attention Weight Caching

python
from dlm.response import AttentionWeightCache

cache = AttentionWeightCache(capacity=1024)

# Caching is integrated into ChainTreeLink
# Weights are automatically cached and invalidated on coordinate updates

Validation

All inputs are validated automatically:

python
from dlm.response import (
    ContentValidator,
    CoordinateValidator,
    ValidationError
)

try:
    ContentValidator.validate_text(
        "short text",
        min_length=20,
        max_length=1000
    )
except ValidationError as e:
    print(f"Validation failed: {e}")

Logging

Structured Logging

python
from dlm.response import get_logger, LogLevel

logger = get_logger(verbose=True, log_level=LogLevel.DEBUG)

# Log with context
logger.info("Processing conversation", step="init", chain_count=10)

# Timed operations
with logger.timed_operation("embedding_generation"):
    embeddings = provider.generate_embeddings(texts)

# Performance metrics
logger.log_performance_metrics("propagation", {
    "steps": 5,
    "converged": True,
    "duration": 0.123
})

Backward Compatibility

python
# Old log_handler still works
from dlm.response import log_handler

log_handler(
    "Processing chains",
    step="build",
    verbose=True,
    level="info"
)

Migration Guide

From Old System

Before:

python
system = ReplyChainSystem(verbose=True)
system.process_conversations(data)

After (no changes required):

python
# Existing code works as-is!
system = ReplyChainSystem(verbose=True)
system.process_conversations(data)

Leveraging New Features

Add embedding caching:

python
from dlm.response import SimpleEmbeddingProvider

provider = SimpleEmbeddingProvider(
    embedding_function=your_model.encode,
    enable_caching=True
)

system = ReplyChainSystem(
    verbose=True,
    embedding_provider=provider
)

Use context archival:

python
history = system.prepare_conversation_history(
    prompt=user_prompt,
    use_context_archival=True,
    max_active_chains=15,
    relevance_threshold=0.6
)

Enable validation:

python
from dlm.response import ValidationError

try:
    system.construct_reply_chain(prompt=user_input, response=bot_output)
except ValidationError as e:
    print(f"Invalid input: {e}")

Configuration Presets

### Default
- Balanced performance and quality
- 15 active chains
- 10 max propagation steps

Performance-Optimized

python
config = ResponseConfig.create_performance_optimized()
# - 10 active chains
# - 5 max propagation steps
# - Higher learning rate (0.2)

Quality-Optimized

python
config = ResponseConfig.create_quality_optimized()
# - 25 active chains
# - 15 max propagation steps
# - Lower convergence threshold
# - Lower relevance threshold (0.5)

Best Practices

1. Enable Caching for Production

python
provider = SimpleEmbeddingProvider(
    embedding_function=model.encode,
    cache_capacity=512,  # Larger cache for production
    cache_ttl=3600,      # 1 hour TTL
    enable_caching=True
)

2. Use Context Archival for Long Conversations

python
if len(system.get_chains()) > 20:
    system.chain_tree.archive_chains_by_relevance(
        current_focus=current_prompt,
        min_relevance=0.6
    )

3. Monitor Cache Performance

python
stats = provider.get_cache_stats()
if stats['hit_rate'] < 0.3:
    # Consider increasing cache capacity
    pass

4. Validate User Inputs

python
from dlm.response import ConversationDataValidator, ValidationError

try:
    ConversationDataValidator.validate_list(user_conversation_data)
except ValidationError as e:
    return {"error": str(e)}

5. Use Structured Logging

python
logger = get_logger(verbose=True)

with logger.timed_operation("conversation_processing"):
    system.process_conversations(data)

logger.log_performance_metrics("system", {
    "chains": len(system.get_chains()),
    "cache_hits": provider.get_cache_stats()['hits']
})

Troubleshooting

### High Memory Usage
- Reduce `cache_capacity` in embedding provider
- Lower `max_active_chains` in context archival
- Enable aggressive archival with higher `relevance_threshold`

### Slow Performance
- Enable embedding caching
- Use batch processing for multiple embeddings
- Reduce `max_propagation_steps` in I-RCP

### Low Cache Hit Rate
- Increase `cache_capacity`
- Check if identical texts are being embedded multiple times
- Consider increasing `cache_ttl`
