• Title: Data leakage in cross-modal retrieval training: A case study
• Authors: Benno Weck and Xavier Serra
• Abstract summary: We study the recently proposed SoundDesc benchmark dataset, which was automatically sourced from the BBC Sound Effects web page. We find that SoundDesc contains several duplicates that cause leakage of training data to the evaluation data. We propose new training, validation, and testing splits for the dataset that we make available online.

• Abstract: The recent progress in text-based audio retrieval was largely propelled by the release of suitable datasets. Since the manual creation of such datasets is a laborious task, obtaining data from online resources can be a cheap solution to create large-scale datasets. We study the recently proposed SoundDesc benchmark dataset, which was automatically sourced from the BBC Sound Effects web page. In our analysis, we find that SoundDesc contains several duplicates that cause leakage of training data to the evaluation data. This data leakage ultimately leads to overly optimistic retrieval performance estimates in previous benchmarks. We propose new training, validation, and testing splits for the dataset that we make available online. To avoid weak contamination of the test data, we pool audio files that share similar recording setups. In our experiments, we find that the new splits serve as a more challenging benchmark.

  Real-world datasets often contain redundant and noisy data, imposing a negative impact on training efficiency and model performance. Data selection has shown promise in identifying the most representative samples from the entire dataset. We propose a novel CLIP-powered data selection framework that leverages multimodal information for more robust and generalizable sample selection.

  In low-resource settings, the amount of seed data samples to use for data augmentation is very small. We propose a novel method that augments training data by incorporating a wealth of examples from other datasets. This approach can ensure that the generated data is not only relevant but also more diverse than what could be achieved using the limited seed data alone.

  Large volumes of text data have contributed significantly to the development of large language models.

We take a wider view and explore scalable estimates of data quality that can be used to measure the quality of pretraining data.
