DeTiME: Diffusion-Enhanced Topic Modeling using Encoder-decoder based LLM (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Neural Topic Models and Large Language Models (LLMs) primarily use contextual embeddings from LLMs, which are not optimal for clustering or topic generation. |
| Approach: | They propose a framework that leverages Encoder-Decoders to generate highly clusterable embeddings that could generate topics that exhibit enhanced clusterability and enhanced semantic coherence compared to existing methods. |
| Outcome: | The proposed framework is efficient to train and exhibits high adaptability, demonstrating its potential for a wide array of applications. |
Synthesizing Conversations from Unlabeled Documents using Automatic Response Segmentation (2024.findings-acl)
Copied to clipboard
| Challenge: | Several datasets have been developed for building conversational question answering systems. |
| Approach: | They propose a robust dialog synthesising method that learns segmentation instead of using sentence boundaries. |
| Outcome: | The proposed method achieves superior quality when compared to WikiDialog . it also improves performance across OR-QuAC benchmarks . |

| Challenge: | Existing approaches to disentangle biased knowledge from reasoning are sub-optimal . entangled data makes curation difficult, leading to inclusion of sensitive, toxic data. |
| Approach: | They propose a framework that selectively removes biased knowledge while preserving reasoning abilities. |
| Outcome: | The proposed framework improves fairness accuracy by 14.7% and reasoning performance by 62.6% across multiple LLMs. |
