Uncertainty-Aware Balancing for Multilingual and Multi-Domain Neural Machine Translation Training (2021.emnlp-main)

Copied to clipboard

Challenge: MultiUAT dynamically adjusts training data usage based on model’s uncertainty on a small set of trusted clean data for multi-corpus machine translation.
Approach: They propose an approach that dynamically adjusts the training data usage based on the model’s uncertainty on a small set of trusted clean data for multi-corpus machine translation.
Outcome: The proposed approach outperforms baselines on 16 languages and 2 domains on English-German translation.
KEEP CHATTING! An Attractive Dataset for Continuous Conversation Agents (2024.findings-acl)

Copied to clipboard

Challenge: Existing works about persona dialogue such as PersonaChat have greatly facilitated the chatbot with configurable and persistent personalities.
Approach: They propose to collect a dataset called ContinuousChat and rewrite it in style-specific ways to increase users' willingness to continue chatting.
Outcome: The proposed model increases users' willingness to continue talking to the chatbot by increasing their personas to detailed-personas through experiences, daily life, future plans, or interesting stories.
Pan More Gold from the Sand: Refining Open-domain Dialogue Training with Noisy Self-Retrieval Generation (2022.coling-1)

Copied to clipboard

Challenge: Existing methods for generating open-domain dialogue systems underutilize training data.
Approach: They propose a retrieval-generation training framework that takes advantage of heterogeneous training data by considering them as "evidence" they use BERTScore retrieval framework which gives better qualities of the training data, they show .
Outcome: The proposed method performs well on zero-shot experiments and is more robust to real-world data.
DGoT: Dynamic Graph of Thoughts for Scientific Abstract Generation (2024.lrec-main)

Copied to clipboard

Challenge: Existing methods for generating abstracts involve collecting domain data and training corresponding models to complete the task of text summarization.
Approach: They propose a method to train language models based on domain datasets and a Dynamic Graph of Thought (DGoT) which inherits the advantages of existing GoT prompt approach while reducing model reasoning cost.
Outcome: The proposed method saves the cost of model training and improves reliability due to the hallucination problem of LLMs.
Towards Identifying Social Bias in Dialog Systems: Framework, Dataset, and Benchmark (2022.findings-emnlp)

Copied to clipboard

Challenge: a number of safety concerns hinder the deployment of open-domain dialog systems, such as offensive languages and toxic behaviors, such social bias is difficult to detect.
Approach: They propose a Dial-Bias Framework for analyzing social bias in conversations . they introduce a Chinese social bias dialog dataset and conduct in-depth ablation studies .
Outcome: The proposed framework is the first annotated Chinese social bias dialog dataset . the proposed framework also provides a fine-grained dialog bias measurement benchmark .
Compilable Neural Code Generation with Compiler Feedback (2022.findings-acl)

Copied to clipboard

Challenge: Existing deep-learning approaches model code generation as text generation, but few of them account for compilability of the generated programs.
Approach: They propose a three-stage pipeline utilizing compiler feedback for compilable code generation to improve compilability.
Outcome: The proposed pipeline improves compilability of generated programs by combining compiler feedback, language model fine-tuning, and compilable discrimination.
DA-Code: Agent Data Science Code Generation Benchmark for Large Language Models (2024.emnlp-main)

Copied to clipboard

Challenge: DA-Code is a code generation benchmark designed to assess LLMs on agent-based data science tasks.
Approach: They propose a code generation benchmark specifically designed for LLMs on agent-based data science tasks.
Outcome: The benchmark performs better than existing frameworks, but lacks accuracy . it is based on real-world data, and includes examples that cover a wide range of tasks .
