Learning Multi-Step Reasoning by Solving Arithmetic Tasks (2023.acl-short)
Copied to clipboard
| Challenge: | Recent studies have demonstrated large LMs’ impressive performance in solving math problems, but such ability seems only to emerge from models with abundant parameters. |
| Approach: | They propose to continuously pre-train LMs with the capabilities of multi-step reasoning by continuously pretraining them on a synthetic dataset MsAT. |
| Outcome: | The proposed method improves LMs' multi-step reasoning abilities on four math word problem datasets. |
Self-Training with Direct Preference Optimization Improves Chain-of-Thought Reasoning (2024.acl-long)

| Challenge: | Recent studies focus on enhancing large-scale language models' reasoning abilities, but the research question of how to GSM8K Performance vs. computational cost remains. |
| Approach: | They propose to train small-scale language models with their own outputs to avoid relying on large models' outputs. |
| Outcome: | The proposed approach outperforms baseline models with comparable sizes while minimizing the required compute. |
Differentiable Data Augmentation for Contrastive Sentence Representation Learning (2022.emnlp-main)
Copied to clipboard
| Challenge: | a contrastive learning framework is used to fine-tune pre-trained language models with unlabeled sentences or labeled sentences. |
| Approach: | They propose a method that makes hard positives from unlabeled sentences . they use a prefix attached to a model to allow for differentiable data augmentation . |
| Outcome: | The proposed method yields significant improvements over existing methods under semi-supervised and supervised settings. |
From Tens of Hours to Tens of Thousands: Scaling Back-Translation for Speech Recognition (2025.emnlp-main)
Copied to clipboard
| Challenge: | Recent advances in Automatic Speech Recognition (ASR) have been fueled by massive speech corpora, but extending coverage to diverse languages with limited resources remains a formidable challenge. |
| Approach: | They propose a pipeline that converts large-scale text corpora into synthetic speech using off-the-shelf text-to-speech (TTS) models. |
| Outcome: | The proposed pipeline generates 500,000 hours of synthetic speech in ten languages and achieves transcription error reductions of over 30%. |
