John Platt on AI for Science: an Oscar, two asteroids, and the algorithm in your sklearn
What happened
John Platt 是 Platt scaling 和 SMO 算法的发明人，现在在 Google 带队做 ERA 项目。ERA 的思路是把科学问题变成一个可打分的任务，然后用 Gemini 自动迭代实验，搜索方式类似蒙特卡洛树搜索。从 Gemini 2.0 换到 2.5 之后，这个系统直接从跑不通变成能高效产出，已经产出了至少 10 篇论文。Pla...

John Platt, inventor of Platt scaling and SMO, leads Google's ERA project. ERA turns scientific problems into scoreable tasks and uses Gemini to auto-iterate experiments via a Monte Carlo tree search variant. The jump from Gemini 2.0 to 2.5 made it go from broken to highly productive, yielding at least 10 papers. Platt warns against overfitting and says always start with linear regression or SVM. The post also covers his team's work on contrail mitigation, which accounts for 1% of human-induced global warming.
