Deep, honest explainers of recent papers I find genuinely interesting. The lens is narrow on purpose: giving LLMs intrinsic motivation (the closest thing to emotions / internal drives) and RL loops built on simple reward signals instead of elaborate RLVR machinery. Efficiency tweaks and incremental gains are deliberately excluded.
Each card links to a full walkthrough: the bold idea, exactly what they did (the real method, with the reward definition), the results with real numbers, and my honest take on whether it holds up. Curated by taste, not comprehensive — and shaped by your feedback at the bottom of every page.
🔥 The approaches & the math that separates them ↗ a synthesis by method (surprise, novelty, information gain, learning progress, empowerment, homeostasis) — the actual reward formula for each, explained simply, with the papers that use it. Start here to understand the subject.
📚 The ranked field map — 84 papers ↗ the whole literature as one top-to-bottom reading list.
🗺️ Prior art & landmines — 204 papers ↗ the continual-learning side of the map: continual pretraining, learnability-based data selection, self-improving agents, and every documented failure mode — ranked into 4 tiers with a "why it matters" note per paper.
