CoCoa: An Encoder-Decoder Model for Controllable Code-switched Generation (2022.emnlp-main)
Copied to clipboard
| Challenge: | Generating code-switched text with fine-grained control on the degree of code-witching and the lexical choices used to convey formality has been well-explored. |
| Approach: | They propose to generate code-switched text with fine-grained control on the degree of code-changing and lexical choices used to convey formality. |
| Outcome: | The proposed model can be invoked at test-time to synthesize code-switched text faithful to syntactic and lexical attributes relevant to code-witching. |
ReTAG: Reasoning Aware Table to Analytic Text Generation (2023.emnlp-main)
Copied to clipboard
| Challenge: | Table to text models generate descriptive summaries that repeat information contained within a table in sentences. |
| Approach: | They propose a table-aware table-to-text model that uses vector-quantization to infuse different types of analytical reasoning into the output. |
| Outcome: | The proposed model achieves 2.2%, 2.9% improvement on PARENT metric over state-of-the-art models. |

| Challenge: | Increasingly, people are forced to use the Web in languages they have low literacy in due to technology asymmetries. |
| Approach: | They propose a method to mine phoneme confusions for pairs of L1 and L2 and plug them into a generative model for synthetically producing corrupted L2 text. |
| Outcome: | The proposed method corrupts the popular language understanding benchmark SuperGLUE and improves performance. |
FRACTAL: Fine-Grained Scoring from Aggregate Text Labels (2025.acl-long)
Copied to clipboard
| Challenge: | Recent studies indicate that finer sentence or span-level labels provide more accurate and interpretable feedback for LLM optimization. |
| Approach: | They propose a suite of models to disaggregate response-level labels into sentence-level (pseudo-)labels through Multiple Instance Learning and Learning from Label Proportions (LLP) formulations. |
| Outcome: | The proposed model can reach 93% of the performance of the fully supervised baseline while requiring only around 10% of the gold labels. |
T-STAR: Truthful Style Transfer using AMR Graph as Intermediate Representation (2022.emnlp-main)
Copied to clipboard
| Challenge: | Unavailability of parallel corpora for training text style transfer models is a challenge but common . a large corpus of parallel data is not available for text style transfers . |
| Approach: | They propose to use AMR as an intermediate style agnostic representation to train TST models. |
| Outcome: | The proposed model outperforms state-of-the-art models in the style agnostic task. |
HintedBT: Augmenting Back-Translation with Quality and Transliteration Hints (2021.emnlp-main)
Copied to clipboard
| Challenge: | HintedBT provides hints (as source tags on the encoder) about the quality of each source-target pair. |
| Approach: | They propose a method which provides hints to the encoder and decoder to improve the quality of BT data by providing hints about the quality. |
| Outcome: | The proposed method improves translation quality and performance in three low/medium-resource language pairs. |
DIMSIM: Distilled Multilingual Critics for Indic Text Simplification (2024.findings-acl)
Copied to clipboard
| Challenge: | Existing approaches to improve the quality of responses generated by large language models (LLMs) however, these critique-refine steps require multiple expensive LLM calls. |
| Approach: | They propose to use critique distillation to train critic models that are trained on input-critique pairs generated by an LLM. |
| Outcome: | The proposed model trains two separate critics that focus on lexical and structure complexity, and is more effective than using an LLM directly as a critic in both 0-shot and few-shot settings. |
