Working with AutoAI RAG class and rag_optimizer¶
The AutoAI experiment class is responsible for creating experiments and scheduling training. All experiment results are stored automatically in the user-specified Cloud Object Storage (COS). Then the AutoAI feature can fetch the results and provide them directly to the user for further usage.
Configure rag_optimizer with one data source¶
For an AutoAI object initialization, you need watsonx.ai credentials (with your API key and URL) and either the project_id or space_id.
Hint
You can copy the project_id from the Project’s Manage tab (Project -> Manage -> General -> Details).
from ibm_watsonx_ai.experiment import AutoAI
experiment = AutoAI(wx_credentials,
space_id='76g53e0-0b32-4a0e-9152-3d50324855ddb'
)
rag_optimizer = experiment.rag_optimizer(
name='AutoAI RAG test',
description='Sample description',
foundation_models=[
"meta-llama/llama-3-70b-instruct",
"ibm/granite-13b-chat-v2"
],
embedding_models=[
"ibm/slate-125m-english-rtrvr",
"intfloat/multilingual-e5-large"
],
max_number_of_rag_patterns=5,
optimization_metrics=[AutoAI.RAGMetrics.ANSWER_CORRECTNESS],
)
Get configuration parameters¶
To see the current configuration parameters, call the get_params() method.
config_parameters = rag_optimizer.get_params()
print(config_parameters)
{
'name': 'RAG AutoAi tests without vector_store_references',
'description': 'Sample description',
'chunking_methods': None,
'embedding_models': [
'ibm/slate-125m-english-rtrvr',
'intfloat/multilingual-e5-large'
],

'ibm/granite-13b-chat-v2'
],
'max_number_of_rag_patterns': 5,
'optimization_metrics': ['answer_correctness']
}
Run rag_optimizer¶
To schedule an AutoAI RAG experiment, call the run() method. This will trigger a training and an optimization process on watsonx.ai.
The run() method can be synchronous (background_mode=False) or asynchronous (background_mode=True).
If you don’t want to wait for the fit to end, invoke the async version. It immediately returns only run details.
run_details = rag_optimizer.run(
input_data_references=[input_data_connection],
test_data_references=[test_data_connection],
results_reference=results_connection,
background_mode=True
)
# OR
run_details = rag_optimizer.run(
input_data_references=[input_data_connection],
test_data_references=[test_data_connection],
results_reference=results_connection,
background_mode=False
)
Get the run status and run details¶
If you use the run() method asynchronously, you can monitor the run details and status using the following two methods:
status = rag_optimizer.get_run_status()
print(status)
'running'
# OR
'completed'
run_details = rag_optimizer.get_run_details()
print(run_details)
RAG Optimizer summary¶
It is possible to get a ranking of all the computed pattern, sorted based on a scoring metric supplied when configuring the optimizer (optimization_metrics parameter).
The output type is a pandas.DataFrame with pattern names, computation timestamps, machine learning metrics, and the number of enhancements implemented in each of the pattern.
rag_optimizer.summary()
rag_optimizer.summary(scoring='answer_correctness')
rag_optimizer.summary(scoring=['answer_correctness', 'context_correctness'])
# Result:
# mean_answer_correctness ... ci_high_faithfulness
# Pattern_Name
# Pattern3 0.79165 ... 0.5102
# Pattern1 0.72915 ... 0.4839
# Pattern2 0.64585 ... 0.8333
# Pattern4 0.64585 ... 0.5312
Get pattern details¶
To see the pattern details, use the get_pattern_details() method.
If you leave pattern_name empty, the method returns the details of the best computed pattern.
pattern_params = rag_optimizer.get_pattern_details(pattern_name='Pattern3')
print(pattern_params)

Get pattern¶
Use the get_pattern() method to load a specific pattern.
If you leave pattern_name empty, the method returns the details of the best computed pattern.
pattern = rag_optimizer.get_pattern(pattern_name='Pattern3')
print(type(pattern))
'ibm_watsonx_ai.foundation_models.extensions.rag.pattern.pattern.RAGPattern'

To download specified inference notebook from Service use the get_inference_notebook().
If you leave pattern_name empty, the method download notebook of the best computed pattern.
rag_optimizer.get_inference_notebook(pattern_name='Pattern3')
To download specified indexing notebook from Service use the get_indexing_notebook().
If you leave pattern_name empty, the method download notebook of the best computed pattern.
rag_optimizer.get_indexing_notebook(pattern_name='Pattern3')
Get logs¶
