Basreh or Basra? Geoparsing Historical Locations in the Svoboda Diaries (2024.acl-srw)
Copied to clipboard
| Challenge: | In the historical domain, many geoparsing corpora are from large news collections. |
| Approach: | They propose a pipeline employing named entity recognition for geotagging and a map-based generate-and-rank approach incorporating candidate name augmentation and clustering of location context words for geocoding. |
| Outcome: | The proposed pipeline outperforms existing map-based geoparsers in terms of accuracy, lowest mean distance error, and number of locations correctly identified. |
Calibrating Language Models with Adaptive Temperature Scaling (2024.emnlp-main)
Copied to clipboard
| Challenge: | Large language models' confidence scores are degraded after fine-tuning with reinforcement learning from human feedback. |
| Approach: | They propose a post-hoc calibration method that predicts a temperature scaling parameter for each token prediction. |
| Outcome: | Adaptive temperature scaling improves calibration by over 10% compared to prior methods . RLHF fine-tuning improves model accuracy, but degradation is not significant . |
