A new self-supervised embedding model trained on the LILY ocean drilling database demonstrates that expert lithological labels do not improve its ability to predict marine sediment properties. The model, which uses physical, chemical, and magnetic measurements from 296 boreholes, achieves comparable or better results in separating geologist-assigned lithologies and predicting absent physical properties without relying on these labels. Researchers found that incorporating lithological labels actually degraded the model's performance, suggesting that these categories compress continuous measurements and discard valuable information about the rock's formation processes.
