TableGPT: Few-shot Table-to-Text Generation with Table Structure Reconstruction and Content Matching (2020.coling-main)
Copied to clipboard
| Challenge: | Recent studies show that pre-trained language models can produce informative and fluent text with the help of large-scale datasets, but they suffer insufficient learning problem with limited training data. |
| Approach: | They propose to use table transformation module with template to rewrite structured table in natural language as input for GPT-2 and exploit multi-task learning with two auxiliary tasks to preserve table’s structural information. |
| Outcome: | The proposed model outperforms existing systems on most few-shot settings. |
Improving Controllable Text Generation with Position-Aware Weighted Decoding (2022.findings-acl)
Copied to clipboard
| Challenge: | Controllable text generation is a challenging task in natural language generation, which aims to generate diverse text related to specified attributes. |
| Approach: | They propose a framework that uses a lightweight controller to adjust bias signals from the controller at different decoding positions. |
| Outcome: | Experiments on positive sentiment control, topic control, and language detoxification show the proposed framework works on 4 SOTA models. |
Table-to-Text Generation with Effective Hierarchical Encoder on Three Dimensions (Row, Column and Time) (D19-1)
Copied to clipboard
| Challenge: | Seq2Seq models for table-to-text generation have achieved remarkable progress, but modeling table representation in one dimension is inadequate. |
| Approach: | They propose to model each table cell considering other records in the same row and to enrich table’s representation by modeling each cell in context of other cells in the similar column or with historical data respectively. |
| Outcome: | The proposed model outperforms baseline and state-of-the-art models on ROTOWIRE, a benchmark dataset of NBA basketball games. |
Controllable Text Generation via Probability Density Estimation in the Latent Space (2023.acl-long)
Copied to clipboard
| Challenge: | Existing control approaches cannot effectively model complex space with diverse attributes, high dimensionality, and asymmetric structure, leaving subsequent controls unsatisfactory. |
| Approach: | They propose a control framework using probability density estimation in the latent space and an invertible transformation function that maps the complex distributions to simple Gaussian distributions in the prior space. |
| Outcome: | The proposed method outperforms baselines on attribute relevance and text quality, achieving a new SOTA. |
A Distributional Lens for Multi-Aspect Controllable Text Generation (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods for multi-aspect control suffer from attribute degeneration due to mutual interference of these controllers. |
| Approach: | They propose to use attribute fusion to find the intersections of multiple attributes as their combination for generation. |
| Outcome: | The proposed method outperforms baselines on attribute relevance and text quality and achieves the SOTA. |

| Challenge: | **Copyright Detective** is the first interactive forensic system for detecting, analyzing, and visualizing potential copyright risks in LLM outputs. |
| Approach: | They propose a system that detects copyright infringements and visualizes them . they use content recall testing, paraphrase-level similarity analysis and persuasive jailbreak probing . |
| Outcome: | The proposed system detects, analyzes, and visualizes potential copyright risks in LLM outputs. |
Enhancing Content Planning for Table-to-Text Generation with Data Understanding and Verification (2020.findings-emnlp)
Copied to clipboard
| Challenge: | Table-to-text models that select and order salient data and verbalize them fluently are lacking in content planning stage. |
| Approach: | They propose to enhance neural content planning by understanding data values with contextual numerical value representations that bring the sense of value comparison into content planning. |
| Outcome: | The proposed model outperforms existing systems with respect to content planning metrics on ROTOWIRE and MLB datasets. |
