Indomee

Indomee is a Python package designed to simplify the evaluation of retrieval-augmented generation (RAG) models and other retrieval-based systems. With indomee, you can compute common evaluation metrics like recall and mean reciprocal rank (MRR) at various levels of k, all through a straightforward API.

We also provide support for simple bootstrapping at the moment with t-testing coming soon.

Installation

pip install indomee

You can get started with indomee with the following example

Indomee provides functions to calculate various metrics such as Mean Reciprocal Rank (MRR) and Recall.

Example Usage

from indomee import calculate_mrr, calculate_recall, calculate_metrics_at_k

mrr = calculate_mrr([1, 2, 3], [2, 3, 4])
print("MRR:", mrr)
# > MRR: 0.5

# Calculate Recall
recall = calculate_recall([1, 2, 3], [2])
print("Recall:", recall)
# > Recall: 1

# Calculate metrics at specific k values
metrics = calculate_metrics_at_k(
    metrics=["recall"], preds=[1, 2, 3], labels=[2], k=[1, 2, 3]
)
print("Metrics at k:", metrics)
# > {'recall@1': 0.0, 'recall@2': 1.0, 'recall@3': 1.0}

2. Bootstrapping

Indomee also supports bootstrapping for more robust metric evaluation.

Example Usage

from indomee import bootstrap_sample, bootstrap

# Bootstrapping a sample
result = bootstrap_sample(preds=[["a", "b"], ["c", "d"], ["e", "f"]], labels=[["a", "b"], ["c", "d"], ["e", "f"]], n_samples=10, metrics=["recall"], k=[1, 2, 3])
print("Bootstrap Sample Metrics:", result.sample_metrics)

# Bootstrapping multiple samples
result = bootstrap(preds=[["a", "b"], ["c", "d"], ["e", "f"]], labels=[["a", "b"], ["c", "d"], ["e", "f"]], n_samples=10, n_iterations=10, metrics=["recall"], k=[1, 2, 3])
print("Bootstrap Metrics:", result.sample_metrics)

3. T-Testing

For the last portion, we'll show how to perform a t-test between two different results that we've obtained from the different methods.

from indomee import perform_t_tests
import pandas as pd

df = pd.read_csv("./data.csv")

# Calculate the mean for each method
method_1 = df["method_1"].tolist()
method_2 = df["method_2"].tolist()
baseline = df["baseline"].tolist()

results = perform_t_tests(
    baseline, method_1, method_2,
    names=["Baseline", "Method 1", "Method 2"],
    paired=True,
)
results
