The RAG Experiment Accelerator is a versatile tool that helps you conduct experiments and evaluations using Azure AI Search and RAG pattern. This document provides a comprehensive guide that covers everything you need to know about this tool, such as its purpose, features, installation, usage, and more.

The main goal of the RAG Experiment Accelerator is to make it easier and faster to run experiments and evaluations of search queries and quality of response from OpenAI. This tool is useful for researchers, data scientists, and developers who want to:

• Test the performance of different Search and OpenAI related hyperparameters.
• Compare the effectiveness of various search strategies.
• Fine-tune and optimize parameters.
• Find the best combination of hyperparameters.
• Generate detailed reports and visualizations from experiment results.

18 March 2024: Content sampling has been added. This functionality will allow the dataset to be sampled by a specified percentage. The data is clustered by content and then the sample percentage is taken across each cluster to attempt even distribution of the sampled data.

This is done to ensure representative results in the sample that one would get across the entire dataset.

Note: It is recommended to rebuild your environment if you have used this tool before due to new dependencies.

The RAG Experiment Accelerator is config driven and offers a rich set of features to support its purpose:

1. Experiment Setup: You can define and configure experiments by specifying a range of search engine parameters, search types, query sets, and evaluation metrics.

2. Integration: It integrates seamlessly with Azure AI Search, Azure Machine Learning, MLFlow and Azure OpenAI.

3. Rich Search Index: It creates multiple search indexes based on hyperparameter configurations available in the config file.

4. Multiple Document Loaders: The tool supports multiple document loaders, including loading via Azure Document Intelligence and basic LangChain loaders. This gives you the flexibility to experiment with different extraction methods and evaluate their effectiveness.

5. Custom Document Intelligence Loader: When selecting the 'prebuilt-layout' API model for Document Intelligence, the tool utilizes a custom Document Intelligence loader to load the data. This custom loader supports formatting of tables with column headers into key-value pairs (to enhance readability for the LLM), excludes irrelevant parts of the file for the LLM (such as page numbers and footers), removes recurring patterns in the file using regex, and more. Since each table row is transformed into a text line, to avoid breaking a row in the middle, chunking is done recursively by paragraph and line. The custom loader resorts to the simpler 'prebuilt-layout' API model as a fallback when the 'prebuilt-layout' fails. Any other API model will utilize LangChain's implementation, which returns the raw response from Document Intelligence's API.

6. Query Generation: The tool can generate a variety of diverse and customizable query sets, which can be tailored for specific experimentation needs.

7. Multiple Search Types: It supports multiple search types, including pure text, pure vector, cross-vector, multi-vector, hybrid, and more. This gives you the ability to conduct comprehensive analysis on search capabilities and results.

8. Sub-Querying: The pattern evaluates the user query and if it finds it complex enough, it breaks it down into smaller sub-queries to generate relevant context.

9. Re-Ranking: The query responses from Azure AI Search are re-evaluated using LLM and ranked according to the relevance between the query and the context.

10. Metrics and Evaluation: It supports end-to-end metrics comparing the generated answers (actual) against the ground-truth answers (expected), including distance-based, cosine and semantic similarity metrics. It also includes component-based metrics to assess retrieval and generation performance using LLMs as judges, such as context recall or answer relevance, as well as retrieval metrics to assess search results (e.g. MAP@k).

11. Report Generation: The RAG Experiment Accelerator automates the process of report generation, complete with visualizations that make it easy to analyze and share experiment findings.

12. Multi-Lingual: The tool supports language analyzers for linguistic support on individual languages and specialized (language-agnostic) analyzers for user-defined patterns on search indexes. For more information, see Types of Analyzers.

13. Sampling: If you have a large dataset and/or want to speed up the experimentation, a sampling process is available to create a small but representative sample of the data for the percentage specified. The data will be clustered by content and a percentage of each cluster will be selected as part of the sample. Results obtained should be roughly indicative of the full dataset within a ~10% margin. Once an approach has been identified, running on the full dataset is recommended for accurate results.

• Azure AI Search Service (Note: Semantic Search is available in Azure AI Search, at Basic tier or higher.)
• Azure OpenAI Service or access to the OpenAI API
• Azure Machine Learning Resources

At the moment, the RAG Experiment Accelerator can be run locally leveraging one of the following:

• Run within a development container
• Install locally on your host machine.

Using a development container will mean that all of the required software is installed for you. This will require WSL. For more information about development containers visit containers.dev

Install the following software on the host machine you will perform the deployment from:

1. For Windows - Windows Store Ubuntu 22.04.3 LTS
2. Docker Desktop
3. Visual Studio Code
4. VS Code Extension: Remote-Containers

Further guidance of setting up WSL can be found here. Now you have the prerequisites, you can:

1. Clone the repository: Clone the accelerator's repository in your WSL terminal.

git clone https://github.com/microsoft/rag-experiment-accelerator.git
code .

Once the project opens in vscode it should ask you if you would like to "Reopen this in a development container". Say yes.

You can of course run the RAG Experiment Accelerator on a Windows/Mac machine if you like; you are responsible for installing the correct tooling. Follow these installation steps:

1. Clone the repository: Clone the accelerator's repository from [GitHub].

git clone https://github.com/microsoft/rag-experiment-accelerator.git

2. Execute the requirements.txt in a conda (first install Anaconda/Miniconda) or virtual environment (then install a couple of dependencies - prompted on the run) to install the dependencies.

conda create -n rag-experiment python=3.11
conda init bash

Close your terminal, open a new one, and run:

conda activate rag-experiment
pip install .

3. Install Azure CLI and authorize:

az login
az account set  --subscription="<your_subscription_guid>"
az account show

There are 3 options to install all the required azure services:

This project supports Azure Developer CLI.

azd provision

• You can also use azd up if you prefer as this calls azd provision anyway
• Please use the up/down arrows to select your Subscription and Region

Once this has completed you can use the launch configuration to run, or debug the 4 steps and the current environment provisioned by azd will be loaded with the correct values.

If you want to deploy the infrastructure yourself from template you can also click here:

If you don't want to use azd you can use the normal az cli too.

Use following command to deploy.

az login
az deployment sub create --subscription <subscription-id> --location <location>  --template-file infra/main.bicep

Or

To deploy with isolated network use following command. Replace the parameter values with the specifics of your isolated network. You must supply all three parameters (i.e. vnetAddressSpace, proxySubnetAddressSpace and subnetAddressSpace) if you wish to deploy to an isolated network.

az login
az deployment sub create --location <location> --template-file infra/main.bicep \
--parameters vnetAddressSpace=<vnet-address-space> \
--parameters proxySubnetAddressSpace=<proxy-subnet-address-space> \
--parameters subnetAddressSpace=<azure-subnet-address-space>

here is an example with parameter values:

az deployment sub create --location uksouth --template-file infra/main.bicep \
--parameters vnetAddressSpace='10.0.0.0/16' \
--parameters proxySubnetAddressSpace='10.0.1.0/24' \
--parameters subnetAddressSpace='10.0.2.0/24'

To use the RAG Experiment Accelerator locally, follow these steps:

1. Copy the provided .env.template file to a file named .env and update all of the required values. Many of the required values for the .env file will come from resources which have previously been configured and/or can be gathered from resources provisioned in the Provision Infrastructure section. Also note, by default, LOGGING_LEVEL is set to INFO but can be changed to any of the following levels: NOTSET, DEBUG, INFO, WARN, ERROR, CRITICAL.

   cp .env.template .env
   # change parameters manually

2. Copy the provided config.sample.json file to a file named config.json and change any hyperparameters to tailor to your experiment.

   cp config.sample.json config.json
   # change parameters manually

3. Copy any files for ingestion (PDF, HTML, Markdown, Text, JSON or DOCX format) into the data folder.

4. Run 01_index.py (python 01_index.py) to create Azure AI Search indexes and load data into them.

   python 01_index.py
   -d "The directory holding the configuration files and data. Defaults to current working directory"
   -dd "The directory holding the data. Defaults to data"
   -cf "JSON config filename. Defaults to config.json"

5. Run 02_qa_generation.py (python 02_qa_generation.py) to generate question-answer pairs using Azure OpenAI.

   python 02_qa_generation.py
   -d "The directory holding the configuration files and data. Defaults to current working directory"
   -dd "The directory holding the data. Defaults to data"
   -cf "JSON config filename. Defaults to config.json"

6. Run 03_querying.py (python 03_querying.py) to query Azure AI Search to generate context, re-rank items in context, and get response from Azure OpenAI using the new context.

   python 03_querying.py
   -d "The directory holding the configuration files and data. Defaults to current working directory"
   -cf "JSON config filename. Defaults to config.json"

7. Run 04_evaluation.py (python 04_evaluation.py) to calculate metrics using various methods and generate charts and reports in Azure Machine Learning using MLFlow integration.

   python 04_evaluation.py
   -d "The directory holding the configuration files and data. Defaults to current working directory"
   -cf "JSON config filename. Defaults to config.json"

Alternatively, you can run the above steps (apart from 02_qa_generation.py) using an Azure ML pipeline. To do so, follow the guide here.

Sampling will be run locally to create a small but representative slice of the data. This helps with rapid experimentation and keeps costs down. Results obtained should be roughly indicative of the full dataset within a ~10% margin. Once an approach has been identified, running on the full dataset is recommended for accurate results.

Note: Sampling can only be run locally, at this stage it is not supported on a distributed AML compute cluster. So the process would be to run sampling locally and then use the generated sample dataset to run on AML.

If you have a very large dataset and want to run a similar approach to sample the data, you can use the pyspark in-memory distributed implementation in the Data Discovery Toolkit for Microsoft Fabric or Azure Synapse Analytics.

    "sampling": {
        "sample_data": "Set to true to enable sampling",
        "only_run_sampling": "If set to true, this will only run the sampling step and will not create an index or any subsequent steps, use this if you want to build a small sampled dataset to run in AML",
        "sample_percentage": "Percentage of the document corpus to sample",
        "optimum_k": "Set to 'auto' to automatically determine the optimum cluster number or set to a specific value e.g. 15",
        "min_cluster": "Used by the automated optimum cluster process, this is the minimum number of clusters e.g. 2",
        "max_cluster": "Used by the automated optimum cluster process, this is the maximum number of clusters e.g. 30",
    },

The sampling process will produce the following artifacts in the sampling directory:

1. A directory named after the config value job_name containing the subset of files sampled, these can be specified as --data_dir argument when running the entire process on AML.
2. A 2 dimensional scatter plot of the clustered files (by content) selected as the sampled dataset in the sampling folder.
3. A .cvs file of the entire dataset with cluster predictions named "all_cluster_predictions..." and a cvs file with the sampled cluster predictions named "sampled_cluster_predictions...". This can be used for further enriching the dataset, for example, creating a meaningful label per cluster and updates all record. See the Heuristics classifier in the Data Discovery Toolkit as an example or Pixplotml for image data.
4. If the "optimum_k": auto config value is set to auto, the sampling process will attempt to set the optimum number of clusters automatically. This can be overridden if you know roughly how many broad buckets of content exist in your data. An elbow graph will be generated in the sampling folder.

Two options exist for running sampling, namely:

1. Run the entire process locally with sampling, including the index generation and subsequent steps
2. Run only the sampling locally and then use the created sampled dataset to execute on AML

Set the following values to run the indexing process locally:

    "sampling": {
        "sample_data": true,
        "only_run_sampling": false,
        "sample_percentage": 10,
        "optimum_k": auto,
        "min_cluster": 2,
        "max_cluster": 30
    },

If only_run_samplingconfig value is set to true, this will only run the sampling step, no index will be created and any other subsequent steps will not executed. Set the --data_dir argument to directory created by the sampling process which will be:

artifacts/sampling/config.[job_name] and execute the AML pipeline step.

All the values can be lists of elements. Including the nested configurations. Every array will produce the combinations of flat configurations when the method flatten() is called on a particular node, to select 1 random combination - call the method sample().

    }
}

NOTE: When changing the config, remember to change:

• config.sample.json (the example config to be copied by others)
• Github actions config file to be used by tests on CI
• Unit tests config file

embedding_model is an array containing the configuration for the embedding models to use. Embedding model type must be azure for Azure OpenAI models and sentence-transformer for HuggingFace sentence transformer models.

{
    "type": "azure",
    "model_name": "the name of the Azure OpenAI model",
    "dimension": "the dimension of the embedding model. For example, 1536 which is the dimension of text-embedding-ada-002"
}

If you are using a model other than text-embedding-ada-002, you must specify the corresponding dimension for the model in the dimension field; for example:

{
    "type": "azure",
    "model_name": "text-embedding-3-large",
    "dimension": 3072
}

The dimensions for the different Azure OpenAI embeddings models can be found in the Azure OpenAI Service models documentation.

When using the newer embeddings models (v3), you can also leverage their support for shortening embeddings. In this case, specify the number of dimensions you require, and add the shorten_dimensions flag to indicate that you want to shorten the embeddings. For example:

{
    "type": "azure",
    "model_name": "text-embedding-3-large",
    "dimension": 256,
    "shorten_dimensions": true
}

{
    "type": "sentence-transformer",
    "model_name": "the name of the sentence transformer model",
    "dimension": "the dimension of the model. This field is not required if model name is one of ['all-MiniLM-L6-v2', 'all-mpnet-base-v2', 'bert-large-nli-mean-tokens]"
}

Giving an example of an hypothetical answer for the question in query, an hypothetical passage which holds an answer to the query, or generate few alternative related question might improve retrieval and thus get more accurate chunks of docs to pass into LLM context. Based on the reference article - Precise Zero-Shot Dense Retrieval without Relevance Labels (HyDE - Hypothetical Document Embeddings).

The following configuration options turns on this experimentation approaches:

{
    "hyde": "generated_hypothetical_answer"
}

{
    "hyde": "generated_hypothetical_document_to_answer"
}

This feature will generate fine related questions, filter out those which are less than min_query_expansion_related_question_similarity_score percent from the original query (using cosine similarity score), and search documents for each one of them along with the original query, deduplicate results and return them to the reranker and top k steps.

default value for min_query_expansion_related_question_similarity_score is set to 90%, you may change this in the config.json

{
    "query_expansion": true,
    "min_query_expansion_related_question_similarity_score": 90
}

The solution integrates with Azure Machine Learning and uses MLFlow to manage experiments, jobs, and artifacts. You can view the following reports as part of the evaluation process:

all_metrics_current_run.html shows average scores across questions and search types for each selected metric:

The computation of each metric and fields used for evaluation are tracked for each question and search type in the output csv file:

Metrics can be compared across runs:

Metrics can be compared across different search strategies:

Mean average precision scores are tracked and average MAP scores can be compared across search type:

This section outlines common gotchas or pitfalls that engineers/developers/data scientists may encounter while working with RAG Experiment Accelerator.

To successfully utilize this solution, you must first authenticate yourself by logging in to your Azure account. This essential step ensures you have the required permissions to access and manage Azure resources used by it. You might errors related to storing QnA data into Azure Machine Learning Data Assets, executing the query and evaluation step as a result of inappropriate authorization and authentication to Azure. Refer to Point 4 in this document for authentication and authorization.

There might be situations in which the solution would still generate errors despite of valid authentication and authorization. In such cases, start a new session with a brand new terminal instance, login to Azure using steps mentioned in step 4 and also check if the user has contribute access to the Azure resources related to the solution.

This solution utilizes several configuration parameters in config.json that directly impact its functionality and performance. Please pay close attention to these settings:

retrieve_num_of_documents: This config controls the initial number of documents retrieved for analysis. Excessively high or low values can lead to "index out of range" errors due to rank processing of Search AI results.

cross_encoder_at_k: This config influences the ranking process. A high value might result in irrelevant documents being included in the final results.

llm_rerank_threshold: This config determines which documents are passed to the language model (LLM) for further processing. Setting this value too high could create an overly large context for the LLM to handle, potentially leading to processing errors or degraded results. This might also result in exception from Azure OpenAI endpoint.

Before running this solution, please ensure you've correctly set up both your Azure OpenAI deployment name within config.json file and add relevant secrets to environment variables (.env file). This information is crucial for the application to connect to the appropriate Azure OpenAI resources and function as designed. If you're unsure about the configuration data, please refer to .env.template and config.json file. The solution has been tested with GPT 3.5 turbo model and needs further tests for any other model.

During the QnA generation step, you may occasionally encounter errors related to the JSON output received from Azure OpenAI. These errors can prevent the successful generation of few questions and answers. Here's what you need to know:

Incorrect Formatting: The JSON output from Azure OpenAI may not adhere to the expected format, causing issues with the QnA generation process. Content Filtering: Azure OpenAI has content filters in place. If the input text or generated responses are deemed inappropriate, it could lead to errors. API Limitations: The Azure OpenAI service have token and rate limitations that affect the output.

End-to-end evaluation metrics: not all the metrics comparing the generated and ground-truth answers are able to capture differences in semantics. For example, metrics such as levenshtein or jaro_winkler only measure edit distances. The cosine metric doesn't allow the comparison of semantics either: it uses the textdistance token-based implementation based on term frequency vectors. To calculate the semantic similarity between the generated answers and the expected responses, consider using embedding-based metrics such as Bert scores (bert_).

Component-wise evaluation metrics: evaluation metrics using LLM-as-judges aren't deterministic. The llm_ metrics included in the accelerator use the model indicated in the azure_oai_eval_deployment_name config field. The prompts used for evaluation instruction can be adjusted and are included in the prompts.py file (llm_answer_relevance_instruction, llm_context_recall_instruction, llm_context_precision_instruction).

Retrieval-based metrics: MAP scores are computed by comparing each retrieved chunk against the question and the chunk used to generate the qna pair. To assess whether a retrieved chunk is relevant or not, the similarity between the retrieved chunk and the concatenation of the end user question and the chunk used in the qna step (02_qa_generation.py) is computed using the SpacyEvaluator. Spacy similarity defaults to the average of the token vectors, meaning that the computation is insensitive to the order of the words. By default, the similarity threshold is set to 80% (spacy_evaluator.py).
