Nvidia thinks AI can solve electrical grid problems caused by AI
Nvidia announced Thursday it’s partnering with EPRI, a power industry R&D organization, to use AI to solve problems facing the electrical grid. Perhaps ironically, the issues are largely caused by rising power demand from AI itself. The Open Power AI Consortium, which includes a number of electrical utilities and tech companies, says it will use what …

How We Learn Step-Level Rewards from Preferences to Solve Sparse-Reward Environments Using Online Process Reward Learning
In this tutorial, we explore Online Process Reward Learning (OPRL) and demonstrate how we can learn dense, step-level reward signals from trajectory preferences to solve sparse-reward reinforcement learning tasks. We walk through each component, from the maze environment and reward-model network to preference generation, training loops, and evaluation, while observing how the agent gradually improves …
