Learning to Coach for Experiential Learning
Learning to Coach trains a dedicated LLM coach to extract transferable experiential knowledge from a frozen actor's trajectories, beating self-refinement.
Learning to Coach (L2C) trains an LLM-as-a-Coach to extract actionable experiential knowledge from a frozen actor model's previous solution trajectories, optimizing rewards based on the actor's guided response correctness. It studies same-instance and cross-instance rewards, where cross-instance elicits knowledge that transfers to other problems. Across mathematical reasoning and interactive text-games, L2C outperforms self-refinement and untrained coaches, scales better with extra inference iterations than larger decoding budgets, and transfers to out-of-distribution tasks.

Former TikTok execs built an app that uses AI to teach you how to pose for a photo
Ex-TikTok employees launched Superpose, an iOS camera app using generative AI to suggest photo poses, with $2.2M raised.
Former TikTok employees Melody Chu and Jing Liu launched Superpose, an iOS camera app that generates four AI pose suggestions per photo, with over 22,000 downloads and 190,000 poses generated since July. The app offers five free generations daily, with paid packs of five for $2.99 or 20 for $9.99. The startup raised $2.2 million from Khosla Ventures, Meitu, and OVTR VC, competing with Google's Camera Coach and Adobe's AI photo critique features.
