AI Research

  • François Chollet argues current AI systems are far from the threshold where they can open-endedly self-improve, predicting consistently self-sustaining linear progress rather than sudden explosion when reached @fchollet
  • Chollet explains perfect understanding requires perfect compression; deep learning models requiring millions of parameters for phenomena describable by simple equations have cached data rather than understood it @fchollet
  • Suhail analyzes RL scaling concerns, concluding that scaling to newer, more difficult environments as a "staircase of sigmoids for new tasks, worlds, goals" enables continued progress beyond naive compute scaling @Suhail
  • Nature publishes groundbreaking TabPFN foundation model that finally beats tree-based methods on tabular data, achieving 5,000x speedup by outperforming CatBoost in 2.8 seconds versus 4 hours of tuning @random_walker
  • TabPFN trains entirely on synthetic data from 100+ million artificial datasets generated from causal graphs, learning general prediction strategies without seeing real data @random_walker
  • MIT CSAIL develops system using rigorous mathematics to ensure robots flex, adapt, and interact safely without exceeding force limits @MIT_CSAIL
  • MIT study reveals many "ineffective" neural networks may start from suboptimal points; short-term guidance method transferring structural knowledge boosts performance @MIT_CSAIL
