Advanced Features

This section describes the enhanced capabilities that extend the framework beyond its core functions. These advanced features include Retrieval-Augmented Generation (RAG), inter-agent communication, an evaluation framework, multimodal support, streaming responses, and type safety. Each feature can be enabled and integrated via configuration and modular code design.

1
Retrieval-Augmented Generation (RAG)

Purpose:
RAG enhances the LLM's responses by retrieving relevant documents or context from an external source. This is especially useful when the LLM's internal context is insufficient.

Implementation Details:

Key Methods:

  • index_documents(documents: List[str]): Processes and indexes a list of documents.
  • retrieve(query: str, top_k: int = 3): Retrieves the most relevant documents based on the query.
Example Usage:
from rag import RetrievalAugmentedGeneration

# Initialize RAG module
rag = RetrievalAugmentedGeneration()

# Index a set of documents
documents = [
    "Python is a versatile programming language.",
    "FAISS is used for efficient similarity search.",
    "SentenceTransformers provide robust embeddings for text."
]
rag.index_documents(documents)

# Retrieve context for a query
relevant_docs = rag.retrieve("How do I search efficiently?", top_k=2)
print("Retrieved Documents:", relevant_docs)
2
Agent Communication

Purpose:
Enables messaging and coordination between multiple agents, supporting more complex multi-agent systems.

Implementation Details:

  • Module: agent_communication.py
  • Functionality:
    • Sending messages to other agents.
    • Receiving messages from a communication queue.

Key Methods:

  • send_message(agent_id: str, message: Dict[str, Any]): Sends a message to a designated agent.
  • receive_messages(): Retrieves and clears the current message queue.
Example Usage:
from agent_communication import InterAgentCommunicator

# Create a communicator instance
communicator = InterAgentCommunicator()

# Send a message to agent "AgentX"
communicator.send_message("AgentX", {"text": "Hello, AgentX!"})

# Retrieve messages
messages = communicator.receive_messages()
print("Inter-Agent Messages:", messages)
3
Evaluation Framework

Purpose:
Provides a mechanism to log performance metrics and assess the efficiency and responsiveness of the agent. This is useful for monitoring and iterative improvements.

Implementation Details:

  • Module: evaluation_framework.py
  • Functionality:
    • Logging custom metrics.
    • Evaluating response time.
    • Reporting current performance metrics.

Key Methods:

  • log_metric(name: str, value: Any): Records a performance metric.
  • evaluate_response_time(start_time: float): Computes and logs the response time.
  • report(): Returns a dictionary of logged metrics.
Example Usage:
import time
from evaluation_framework import EvaluationFramework

# Initialize evaluation framework
eval_framework = EvaluationFramework()

# Start a timer and simulate a process
start_time = time.time()
# ... perform some operations ...
time.sleep(0.5)

# Evaluate and log response time
response_time = eval_framework.evaluate_response_time(start_time)
print("Response Time:", response_time)

# Retrieve and print all metrics
metrics_report = eval_framework.report()
print("Metrics Report:", metrics_report)
4
Multimodal Support

Purpose:
Adds the capability to process and analyze non-text data such as images and audio. This can be used to build richer interactive applications.

Implementation Details:

  • Module: multimodal_support.py
  • Libraries Used:
    • Pillow for image processing.

Key Methods:

  • process_image(image_path: str): Processes an image and returns descriptive metadata (e.g., dimensions).
  • process_audio(audio_path: str): (Stub) Processes audio and returns a placeholder message or transcription.
Example Usage:
from multimodal_support import MultimodalProcessor

# Create a processor instance
processor = MultimodalProcessor()

# Process an image file
image_info = processor.process_image("path/to/image.jpg")
print("Image Info:", image_info)

# Process an audio file (stub)
audio_info = processor.process_audio("path/to/audio.mp3")
print("Audio Info:", audio_info)
5
Streaming Responses

Purpose:
Enhances user interaction by streaming the LLM's response incrementally, rather than waiting for a full output. This is especially useful for long responses.

Implementation Details:

  • Module: streaming_responses.py
  • Functionality:
    • Implements a generator to yield chunks of text from the complete response.

Key Methods:

  • stream_response(response: str, chunk_size: int = 20): Yields segments of the response text.
Example Usage:
from streaming_responses import stream_response

full_response = "This is a very long response generated by the agent, which we will stream in small chunks."
print("Streaming Response:")
for chunk in stream_response(full_response, chunk_size=20):
    print(chunk)
6
Type Safety

Purpose:
Ensures that functions receive the correct types of inputs and produce expected types of outputs. This helps catch errors early and improves code robustness.

Implementation Details:

  • Module: type_safety.py
  • Functionality:
    • Validates inputs and outputs using helper functions.

Key Methods:

  • validate_input(value: Any, expected_type: Type, param_name: str = "parameter"): Raises a TypeError if the input type does not match.
  • validate_output(value: Any, expected_type: Type, param_name: str = "output"): Raises a TypeError if the output type does not match.
Example Usage:
from type_safety import validate_input, validate_output

# Validate input parameter
validate_input(123, int, "example_param")

# Validate output type
validate_output("hello", str, "example_output")

print("Type safety checks passed.")

Summary

The advanced features extend the framework by:

  • Enhancing Context: RAG retrieves external documents to supplement responses.
  • Supporting Multi-Agent Systems: Agent communication facilitates coordination between agents.
  • Measuring Performance: The evaluation framework logs metrics to help optimize performance.
  • Processing Multimedia: Multimodal support allows for image and audio processing.
  • Improving Interaction: Streaming responses provide a more dynamic user experience.
  • Ensuring Reliability: Type safety functions prevent type-related errors.

By integrating these advanced features, developers can build richer, more robust, and interactive conversational agents that rival state-of-the-art systems.
