| Challenge: | Using a prototype, we present an automatic speech translation system for live subtitling of conference speech . the system is routinely tested in recognizing English, Czech, and German speech - and presenting it simultaneously into 42 target languages. |
| Approach: | They propose an automatic speech translation system aimed at live subtitling of conference presentations. |
| Outcome: | The proposed system is a working prototype that is routinely tested in recognizing English, Czech, and German speech and presenting it translated simultaneously into 42 target languages. |
Are Natural Language Inference Models IMPPRESsive? Learning IMPlicature and PRESupposition (2020.acl-main)
Copied to clipboard
| Challenge: | Natural language inference (NLI) is an increasingly important task for natural language understanding . however, the ability of NLI models to make pragmatic inferences remains understudied . |
| Approach: | They use semi-automatically generated sentence pairs to evaluate whether NLI models make pragmatic inferences. |
| Outcome: | The proposed model trains on multiNLI and shows that it learns to draw pragmatic inferences. |
Socratic Human Feedback (SoHF): Expert Steering Strategies for LLM Code Generation (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Large Language Models (LLMs) are increasingly used for generating code solutions, but struggle with complex programming problems without human guidance. |
| Approach: | They use the “Socratic Feedback” paradigm to map observed feedback strategies to five stages of Socratic Questioning to identify failures in LLMs. |
| Outcome: | The proposed models solved 74% of the problems that the models initially failed to solve on their own. |
