Revisiting Uncertainty-based Query Strategies for Active Learning with Transformers (2022.findings-acl)
Copied to clipboard
| Challenge: | a recent study has investigated how transformer-based language models can be combined with active learning. |
| Approach: | They propose to combine transformer-based language models with active learning to reduce labeling costs . transformers are expensive, but they can be fine-tuned using a query strategy . they compare transformers to experiments from previous research to evaluate their performance . |
| Outcome: | The proposed model outperforms the well-known prediction entropy query strategy on five widely used text classification benchmarks. |
Small-Text: Active Learning for Text Classification in Python (2023.eacl-demo)
Copied to clipboard
| Challenge: | small-text is an easy-to-use active learning library for text classification . it features a variety of pre-implemented state-of-the-art query strategies and stopping criteria . |
| Approach: | They introduce small-text, an easy-to-use active learning library for Python . it offers pool-based active learning for single- and multi-label text classification . they find it matches vanilla transformer fine-tuning in terms of classification accuracy . |
| Outcome: | The proposed library outperforms vanilla transformer fine-tuning in classification accuracy and area under the curve. |

| Approach: | iLCM project develops integrated research environment for analysis of structured and unstructured data in a "Software as a Service" architecture. |
| Outcome: | iLCM project develops integrated research environment for analysis of structured and unstructured data in a "Software as a Service" architecture. |
Press Freedom Monitor: Detection of Reported Press and Media Freedom Violations in Twitter and News Articles (2021.emnlp-demo)
Copied to clipboard
| Challenge: | Press freedom is under constant and increasing attack, even in Europe. |
| Approach: | They introduce a tool that aims to detect reported press and media freedom violations in news articles and tweets. |
| Outcome: | The tool has shown an impressive performance in detecting press and media freedom violations in news articles and tweets. |

| Challenge: | open pit mines left many regions worldwide inhospitable or uninhabitable . aforementioned information has to be acquired to ensure safety and validity of land reuse . |
| Approach: | They propose a workflow for supporting the post-mining management of former open pit mines in the eastern part of Germany . they use active learning to perform multi-label sentence classification for two categories of restrictions and seven categories of topics . |
| Outcome: | The proposed system supports the post-mining management of former lignite open pit mines in the eastern part of Germany. |
