Leveraging Agents with Bedrock
This notebook should work well with the
Data Science 3.0kernel in SageMaker Studio. You can also run on a local setup, as long as you have the right IAM credentials to invoke the Claude model via Bedrock
In this demo notebook, we demonstrate an implementation of Function Calling with Anthropic's Claude models via Bedrock. This notebook is inspired by the original work by the Anthropic Team and modified it for use with Amazon Bedrock.
This notebook need access to anthropic.claude-3-sonnet-20240229-v1:0 model in Bedrock
Overview
Conversational interfaces such as chatbots and virtual assistants can be used to enhance the user experience for your customers. These use natural language processing (NLP) and machine learning algorithms to understand and respond to user queries and can be used in a variety of applications, such as customer service, sales, and e-commerce, to provide quick and efficient responses to users. usuallythey are augmented by fetching information from various channels such as websites, social media platforms, and messaging apps which involve a complex workflow as shown below
LangGraph using Amazon Bedrock
Building - Key Elements
The first process in a building a contextual-aware chatbot is to identify the tools which can be called by the LLM's.
Second process is the user request orchestration , interaction, invoking and returning the results
Architecture [Retriever + Weather with LangGraph lookup]
We create a Graph of execution by having a supervisor agents which is responsible for deciding the steps to be executed. We create a retriever agents and a weather unction calling agent which is invoked as per the user query. We Search and look for the Latitude and Longitude and then invoke the weather app to get predictions

Bedrock model
Anthropic Claude
The key for this to work is to let LLM which is Claude models know about a set of tools that it has available i.e. functions it can call between a set of tags. This is possible because Anthropic's Claude models have been extensively trained on such tags in its training corpus.
Then present a way to call the tools in a step by step fashion till it gets the right answer. We create a set of callable functions , below e present a sample functions which can be modified to suit your needs

mechanics. It states that the energy of particles or systems can only take on certain specific
values, rather than varying continuously.\n\nSome key points about discrete energies:\n\n- Particles
like electrons can only exist in specific energy levels around the nucleus of an atom, not at any
arbitrary energy value.\n\n- When an electron transitions between allowed energy levels, it absorbs
or emits a quantum of energy with a very specific value related to the energy difference between the
levels.\n\n- This quantization of energy explains phenomena like the discrete line spectra observed
when atoms absorb or emit light of specific wavelengths.\n\n- The allowed energy values depend on
the quantum state of the particle or system, described by its quantum numbers.\n\n- The quantization
arises from the wave-particle duality of matter and the probabilistic nature of quantum
mechanics.\n\n- Discrete energy levels also exist for other systems like nuclei, molecules, and
solids beyond just single atoms.\n\nSo in essence, quantum mechanics rejects the classical idea of
continuous energy values, instead restricting particles and systems to specific quantized energy
states dictated by their quantum mechanical description. This discreteness is fundamental to quantum
theory.'}], 'model': 'claude-3-sonnet-28k-20240229', 'stop_reason': 'end_turn', 'stop_sequence':

It's the driest time of year.\n\n- Winters (December-February) are cool and wet. Average highs are in the mid 40s°F and lows are in the mid 30s°F. It rains frequently during the winter months.\n\n- Spring (March-May) and fall (September-November) are transitional seasons, with a mix of rainy periods and drier stretches. Highs are typically in the 50s and 60s°F.\n\n- Seattle gets an average of 37 inches of rainfall per year, with the wettest months being November through January.\n\n- While Seattle has a reputation for being rainy, it actually gets less annual rainfall than many East Coast cities. However, the rain tends to linger with many overcast/drizzly days.\n\n- Snow is relatively rare, with just a few inches falling during winter in a typical year.\n\nSo in summary, expect cool, wet winters and mild, drier summers in Seattle's temperate maritime climate.

Section 2 -- Agents with tooling
Tools available
- We will connect a Vector DB and expose that as a tool having details of a FAQ
- we will have function invocations to a weather API and leverage that
Create a set of helper function
we will create a set of functions which we can the re use in our application 1. We will need to create a prompt template. This template helps Bedrock models understand the tools and how to invoke them. 2. Create a method to read the available tools and add it to the prompt being used to invoke Claude 3. Call function which will be responsbile to actually invoke the function with the right parameters 4. Format Results for helping the Model leverage the results for summarization 5. Add to prompt. The result which come back need to be added to the the prompt and model invoked again to get the right results

Add Tools
Recursively add the available tools

Use the Default prompt template
Add the retriever tooling
Use In-Memory FAISS DB
Section 2 Use the Langchain-AWS classes
These classes having all the latest api's and working correctly. Now use langchain and annotations to create the tools and invoke the functions
- we will first test with the bind tools to validate and then use the agents

Observation: Amazon SageMaker Clarify is a machine learning bias detection and explanation tool that helps explain model predictions and detect potential bias in machine learning models. Key features of SageMaker Clarify include:
- Bias detection - Detect bias in your training data and models for issues like unintended bias by sensitive data like age, gender, etc.
- Model explainability - Explain how input features impact individual predictions from machine learning models.
- Data and model monitoring - Monitor models in production for data drift, bias drift, and other issues that could impact model performance.
SageMaker Clarify helps increase transparency and accountability for machine learning models by detecting potential bias and providing explanations for how models make predictions.
Thought: The search results provide a good overview of what Amazon SageMaker Clarify is - a tool for detecting bias and explaining predictions from machine learning models. I now have enough information to provide a final answer to the original question.
Final Answer: Amazon SageMaker Clarify is a machine learning tool that helps detect potential bias in training data and models, and provides explanations for how models arrive at their predictions. Its key capabilities include bias detection to surface unintended biases, model explainability to show how input features impact individual predictions, and monitoring for issues like data/bias drift that could degrade model performance over time.

Observation: Here are some relevant excerpts from the SageMaker documentation on Amazon SageMaker Clarify:
"Amazon SageMaker Clarify helps you detect potential bias in machine learning models and increase transparency by explaining how commercial machine learning models make predictions."
"SageMaker Clarify provides machine learning developers with greater visibility into their training data and models so they can identify and explain bias and help ensure that their systems are fair."
"SageMaker Clarify detects potential bias in machine learning models and helps explain model predictions in a clear and understandable way."
"SageMaker Clarify provides bias metrics that detect various types of bias, including:
- Bias in labels or predicted labels
- Bias in inputs or features
- Bias in models"
Thought: The search results provide a good overview of what Amazon SageMaker Clarify is - it is a capability within SageMaker that helps detect potential bias in machine learning models and provides explanations for how models make predictions. This allows developers to increase transparency and fairness in their ML systems.
Final Answer: Amazon SageMaker Clarify is a capability within the Amazon SageMaker machine learning service that helps detect potential bias in machine learning models and increase transparency by explaining how the models make predictions. It provides metrics to detect different types of bias in the training data, model inputs/features, and model outputs. The goal of SageMaker Clarify is to help machine learning developers build fairer and more transparent ML systems by identifying and mitigating sources of bias.[0m
