Controllable Text Generation with Residual Memory Transformer (2024.findings-acl)
Copied to clipboard
| Challenge: | Large-scale Causal Language Models (CLMs) have been successful in text generation, but there is still a challenge to control the generation process. |
| Approach: | They propose a non-intrusive, lightweight control plugin to control the generation process of a CLM at arbitrary time steps. |
| Outcome: | The proposed plugin can handle any type of control conditions and cooperate with the base CLM through a residual learning paradigm. |
Graph-based Multilingual Product Retrieval in E-Commerce Search (2021.naacl-industry)
Copied to clipboard
| Challenge: | Modern e-commerce search systems require product retrieval under multilingual scenarios. |
| Approach: | They propose a universal multilingual retrieval system that captures interactions between search queries and items in e-commerce search. |
| Outcome: | The proposed system outperforms state-of-the-art retrieval models on five countries and has been deployed in production for multiple countries. |

| Challenge: | Structured representations have long been pivotal in computational linguistics, but their role remains ambiguous in the Large Language Models (LLMs) era. |
| Approach: | They propose a framework that integrates structured representations into LLMs from training-free and training-dependent perspectives. |
| Outcome: | The proposed framework integrates structured representations through natural language descriptions in LLM prompts while augmenting the model’s inference capability through fine-tuning on linguistically described structured representation. |
Bi-DCSpell: A Bi-directional Detector-Corrector Interactive Framework for Chinese Spelling Check (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Chinese Spelling Check (CSC) aims to detect and correct potentially misspelled characters in Chinese sentences. |
| Approach: | They propose a bi-directional Detector-Corrector framework for Chinese Spelling Check which mutually enhances the feature representation for detection and correction subtasks. |
| Outcome: | The proposed framework reduces the risk of over-correction and under-corrections while preserving the knowledge learnt from correction. |
