Mar 3, 2025 · Direct preference optimization (DPO) is an alignment technique for large language models, used to adjust model weights based on human preferences. It differs from reinforcement learning from human feedback (RLHF) in that it does not require fitting a reward model and uses simpler binary data preferences for training.

4 days ago · To address these issues, we introduce a novel approach called Hallucination Aware Tuning (HAT). This method involves training hallucination detection models that generate detection labels and provide detailed descriptions of the detected hallucinations.

我们提出的这个算法称为直接偏好优化（Direct Preference Optimization，DPO）。 它具有稳定性、高性能和计算轻量级的特点，不需要拟合奖励模型，不需要在微调时从 LM 中采样，也不需要大量的超参调节。 我们的实验表明了 DPO 可以微调 LMs 以对齐人类偏好，甚至比现有方法更好。 值得注意的是，用 DPO 进行微调在控制生成结果的情感以及改善摘要和单轮对话的响应质量方面表现出更好的能力，同时在实现和训练时的难度大大降低。 从模型广泛的 知识 和 能力 中选 …

Direct Preference Optimization (DPO) 是一种专为大型 语言模型 （LLMs）设计的训练方法，旨在通过人类偏好数据来 优化模型，而无需使用复杂的 强化学习 算法（如Proximal Policy Optimization, PPO）。 DPO 的核心思想是通过偏好数据直接调整模型参数，绕过显式奖励模型的拟合以及复杂的强化学习优化过程。 这种简化的训练方法不仅提高了训练效率，还避免了传统 RLHF 方法中常见的不稳定性。 （3）相较于 RLHF，DPO 训练更加稳定和简化，并且具有与 …

A data protection officer (DPO) ensures, in an independent manner, that an organization applies the laws protecting individuals' personal data. The designation, position and tasks of a DPO within an organization are described in Articles 37, 38 and 39 of the European Union (EU) General Data Protection Regulation (GDPR). [ 1 ]

Sep 23, 2019 · The hat has a low cone shape, more than 18 inches in diameter, with the face of a sculpin or bullhead fish carved into the front of it and a circular platform on top. The hat rested on the shelves of the Smithsonian for nearly 130 years.
