Overview

In this repository you will find:

• A summary of the LingoQA dataset and evaluation metric
• An example of how to run the benchmark on your model predictions
• Details about how to download the datasets
• An example of how to run the novel evaluation metric, Lingo-Judge

3-minute summary

Benchmark

To run the LingoQA benchmark on your predictions, simply install the requirements for the repository:

pip install -r ./requirements.txt

Export the predictions of your model to a predictions.csv file with the columns question_id, segment_id and answer corresponding to the evaluation dataset. You should have 500 answers in the file. Subsequently, run the benchmark using the following command:

python ./benchmark/evaluate.py --predictions_path ./path_to_predictions/predictions.csv

Download Data and Annotations

The LingoQA training and evaluation datasets contain:

• Videos corresponding to driving scenarios
• Language annotations

Evaluation Metric

Lingo-Judge is an evaluation metric that aligns closely with human judgement on the LingoQA evaluation suite.

# Import necessary libraries
from transformers import pipeline

# Define the model name to be used in the pipeline
model_name = 'wayveai/Lingo-Judge'

# Define the question and its corresponding answer and prediction
question = "Are there any pedestrians crossing the road? If yes, how many?"
answer = "1"
prediction = "Yes, there is one"

# Initialize the pipeline with the specified model, device, and other parameters
pipe = pipeline("text-classification", model=model_name)
# Format the input string with the question, answer, and prediction
input = f"[CLS]\nQuestion: {question}\nAnswer: {answer}\nStudent: {prediction}"

# Pass the input through the pipeline to get the result
result = pipe(input)

# Print the result and score
score = result[0]['score']
print(score > 0.5, score)
