PyTorch implementations of algorithms from "Reinforcement Learning: An Introduction by Sutton and Barto", along with various RL research papers.

A team has used a process known as DNA origami to make electrochemical sensors that can quickly detect and measure biomarkers. Using an approach called DNA origami, scientists at Caltech have ...

Concise pytorch implementations of DRL algorithms, including REINFORCE, A2C, Rainbow DQN, PPO(discrete and continuous), DDPG, TD3, SAC, PPO-discrete-RNN(LSTM/GRU). python==3.7.9 numpy==1.19.4 ...

大家都知道，LLM 的训练过程很复杂，其中有两个关键阶段：预训练和后训练。今天咱们就来深入聊聊在这一过程中发挥重要作用的近端策略优化（PPO）算法和组相对策略优化（GRPO）算法。这俩算法不仅在学术圈备受关注，在实际应用中也有着举足轻重的地位 ...

It’s not hyperbole to say that nineteen-year-old UK artist Sienna Spiro is one of the most accomplished and emotive young singers since the arrival of Adele in 2008, flaunting her storytelling on ...

A designer's origami dresses were showcased at London Fashion Week on Saturday. The artist, Darryl Bedford, forms his clever creations using a combination of techniques. This includes the Japanese ...

His short film "Origami" is the first Japanese production to win a Student Academy Award. The work is a paean to his first passion — but more than that, it’s a celebration of the human touch ...

相较于 PPO，GRPO 去掉了价值模型，而是通过分组分数来估计基线，从而可极大减少训练资源。 DeepSeek-R1 技术报告中写到：「具体来说，我们使用 ...
