- Charformer: Fast Character Transformers via Gradient-based Subword Tokenization (2021 · 186 citations)
Most NLP models rely on a subword tokenizer that is fixed before training. This makes them fragile to rare words, typos and noisy text. It also breaks low-resource languages into many fragments and makes adaptation to new domains harder. Feeding raw characters to a Transformer avoids these issues, but the long… - LiPO: Listwise Preference Optimization through Learning-to-Rank (2025 · 31 citations)
Most alignment methods that skip full RLHF, such as DPO and SLiC, learn only from pairs of responses. Human or reward-model feedback, however, often ranks several responses to the same prompt. The authors treat alignment as a Learning-to-Rank (LTR) problem. The prompt plays the role of a query, the sampled responses… - Boosting Reward Model with Preference-Conditional Multi-Aspect Synthetic Data Generation (2024 · 5 citations)
Reward models used to align LLMs need preference data: a prompt, two candidate answers and a label saying which is better.
