Iteration over labels and datasets not working in PPI

[WJ44]

For evaluating RAG systems, the PPI config allows specifying multiple datasets and labels. These labels and datasets are iterated over in the rag_scoring_config method, however there is a return statement in the loop so only the first combination is actually evaluated.

Let me know if you could look into this. I could also make a PR to solve this if you let me know what the expected return value should be in this case.

Hi @WJ44

The issue with the return statement in the loop within the rag_scoring_config method has been resolved, allowing all combinations of datasets and labels to be correctly evaluated.

Could you confirm @WJ44 if this issue has been solved on your side?

I have created an environment to test the results, using ares-ai 0.60.0 library and I am getting very strange results in the output. Every single dataset is different, yet the evaluation I get is the same for every model, like if the variable was being overwritten.

eval_datasets = ['/mnt/data/dataset1.tsv', '/mnt/data/work/dataset2.tsv', '/mnt/data/work/dataset3.tsv', '/mnt/data/work/dataset4.tsv']

ppi_config = {
    "evaluation_datasets": eval_datasets,
    "few_shot_examples_filepath": "data/interim/few_shot_prompt_filename_customized_pytorch_v2.tsv",
    "checkpoints": [
        "notebooks/checkpoints/microsoft-mdeberta-v3-base/5e-06_1_True_Context_Relevance_Label_few_shot_prompt_filename_customized_v2_545281.pt",
        "notebooks/checkpoints/microsoft-mdeberta-v3-base/5e-06_1_True_Answer_Faithfulness_Label_few_shot_prompt_filename_customized_v2_568298.pt",
        "notebooks/checkpoints/microsoft-mdeberta-v3-base/5e-06_1_True_Answer_Relevance_Label_few_shot_prompt_filename_customized_v2_428380.pt",
    ],
    "labels": [
        #"Context_Relevance_Label",
        "Answer_Faithfulness_Label",
        #"Answer_Relevance_Label",
    ],
    "model_choice": "microsoft/mdeberta-v3-base",
    "GPT_scoring": False,
    # This file had to be modified manually to change the column names
    "gold_label_path": "data/interim/gold_queries_pytorch.tsv",
    "swap_human_labels_for_gpt4_labels": False,
}

ares = ARES(ppi=ppi_config)
results = ares.evaluate_RAG()
print(results)

In the output I am getting:

[{'ARES_Prediction': 0.6800000000000054, 'ARES_Confidence_Interval': [0.627, 0.733], 'Number_of_Examples_in_Evaluation_Set': 100, 'Ground_Truth_Performance': None, 'ARES_LLM_Judge_Accuracy_on_Ground_Truth_Labels': None, 'Annotated_Examples_used_for_PPI': 300}, {'ARES_Prediction': 0.6800000000000054, 'ARES_Confidence_Interval': [0.627, 0.733], 'Number_of_Examples_in_Evaluation_Set': 100, 'Ground_Truth_Performance': None, 'ARES_LLM_Judge_Accuracy_on_Ground_Truth_Labels': None, 'Annotated_Examples_used_for_PPI': 300}, {'ARES_Prediction': 0.6800000000000054, 'ARES_Confidence_Interval': [0.627, 0.733], 'Number_of_Examples_in_Evaluation_Set': 100, 'Ground_Truth_Performance': None, 'ARES_LLM_Judge_Accuracy_on_Ground_Truth_Labels': None, 'Annotated_Examples_used_for_PPI': 300}, {'ARES_Prediction': 0.6800000000000054, 'ARES_Confidence_Interval': [0.627, 0.733], 'Number_of_Examples_in_Evaluation_Set': 100, 'Ground_Truth_Performance': None, 'ARES_LLM_Judge_Accuracy_on_Ground_Truth_Labels': None, 'Annotated_Examples_used_for_PPI': 300}]

Additionally, I am not getting the ARES ranking in the output.

Another thing related to the labels and datasets is that if I add more than one label in the output it fails producing any output at all. So for example, if I uncomment the Context_Relevance_Label at the above config and run the evaluation again using Labels: ['Context_Relevance_Label', 'Answer_Faithfulness_Label'] then the response is:

The above exception was the direct cause of the following exception:

KeyError: 'Answer_Faithfulness_Label'

Note that the 'Answer_Faithfulness_Label exists, as it was used for the first evaluation.

I have searched in the updated repo documentation and readme and all the multilabel, multidataset examples have disappeared. Every single example is using just one label and one dataset.

[WJ44]

As far as I can tell, the code in the main branch here still has a return statement in the most nested for loop which seems like it would only evaluate the first combination but perhaps I am missing something.
