LG AI Research has developed AGATa technology that improves training performance while preserving the structure of tabular data.
Details
Tabular Data, which is core to industries such as finance, healthcare, and manufacturing, lacks the spatial or sequential structure found in images or text, so applying existing data augmentation techniques to it risks distorting important relationships within the data.
LG AI Research's Data Intelligence (DI) Lab presented AGATa (Attention-Guided Augmentation) technology at the NeurIPS 2024 TRL workshop. This technology is designed to perform effective augmentation during Contrastive Learning while preserving the core structure of tabular data.
The core operating principles of AGATa are as follows:
- Attention-Guided Feature Selection: Calculates the importance of each feature using the self-attention scores of the Transformer model.
- Dynamic Augmentation: After identifying features with low importance, one of Masking, Shuffling, or CutMix is dynamically applied to maximize data diversity.
This approach can secure high predictive performance even for tabular data generated in complex environments such as real-world manufacturing sites, giving it very high practical value.
