As a strong oxidizing agent, H 2 O 2 markedly inhibited the hFDH activity, as it induced Zn 2+ release from FDH; however, LED-RL treatment reversed H 2 O 2 -inhibited FDH activity by reducing...

数据这块使用Logic-RL 项目生成的 KK数据集 。 这种推理任务基于“骑士与无赖”（Knights and Knaves，简称K&K）谜题构建了一系列数据。 略有不同的是 chat template 没有加<think>，使用了qwen原版的chat template，这可能增加了模型学习生成格式的成本。

Briefly, RL at 630 nm not only directly destroyed Aβ-mediated SP but also activated FDH and degraded FA to reduce FA-facilitated Aβ deposition in the ECS of cortex. Subsequently, it could recover ISF flow and reverse memory deficits in AD model mice.

2019年4月10日 · Illumination with LED-RL markedly activated both catalase and FDH in the brains, cultured cells, and purified protein solutions, all reduced brain H 2 O 2 and FA levels and restored brain Ach contents. Consequently, LED-RL not only prevented early-stage memory decline but also rescued late-stage memory deficits in SAMP8 mice.

2025年2月21日 · 以及此阶段确实验证了Pure Rule Based RL有效性，Val acc一直在涨，不过不如SFT来收益来的快. Step2：高温采样与大量rollout. 数据集过渡到正式的5人谜题，此阶段训练持续最长。也是最容易崩溃的时候。 我训了14版超参，都是崩坏的，泪目，下面讲讲一些好玩的崩 …

2025年2月20日 · Inspired by the success of DeepSeek-R1, we explore the potential of rule-based reinforcement learning (RL) in large reasoning models. To analyze reasoning dynamics, we use synthetic logic puzzles as training data due to their controllable complexity and straightforward answer verification.

2019年1月1日 · To investigate whether Aβ directly inactivates FDH and leads to FA generation, Aβ42 at different concentrations were added into the culture medium of N2a cells. We found that RL at 630 nm could improve FDH activity in N2a cells (Fig. 3A), which was also our previous study of FDH in the pure protein solutions [].

2025年1月28日 · DeepSeek-R1-Zero，通过大规模强化学习 (RL) 训练的模型，无需超级微调 (SFT) 作为初步步骤，展示了卓越的推理能力。通过RL，DeepSeek-R1-Zero自然地出现了许多强大而有趣的推理行为。然而，它面临着可读性差、语言混合等挑战。

2024年12月9日 · 本文提出了Diffusion Policy Policy Optimization（DPPO），结合了扩散模型的能力与RL的优化优势，通过策略梯度（Policy Gradient, PG）方法实现了对Diffusion Policy的高效微调。 与此前针对扩散策略的优化方法相比，DPPO不仅在训练稳定性和任务鲁棒性方面表现优异，还通过结构化的探索与扩散过程的多步迭代，突破了传统观点中策略梯度对扩散策略优化效率低下的限制。 DPPO在各种复杂机器人任务中均展现出强大的能力。 无论是处理像素输入的模 …

2025年2月8日 · 如果我们从 loss 函数 的角度来看 sft 和 rlhf，会发现二者在本质上没有差别：无非都是一个条件概率公式嘛，围绕着 next_token 的 probability 做文章。 只不过在实现细节上，sft 的 next_token 有一个明确的 target，距离这个 target 远 loss 就大，否则 loss 就小；rlhf 的 next_token 则是有一个 reward，如果这个 reward 高就鼓励它，reward 低就打压它。 至于其他区别，那仅仅是两种算法的习惯性用法不同而已。 比如 reference_model，有人规定 sft 的时候 …

1999年10月28日 · The FDH ISMS should support the Hanford Strategic Plan (DOE-RL 1996) to safely clean up and manage the site's legacy waste; deploy science and technology while incorporating the ISMS theme to ''Do work safely''; and protect human health and the …

Within RL, the Transition Programs Division (TPD) has field responsibility for the project. The TPD director is the project manager and is the project interface for DOE-HQ, Fluor Daniel Hanford, Inc.
