The AI Industry Is Laughing at a Brain-Inspired Algorithm. They’ll Regret It.
Sakana AI’s new predictive coding model achieves just 85% on MNIST, prompting the AI community to dismiss it. But in rushing to mock its empirical performance, we are ignoring a biologically plausible learning algorithm that maps to the brain’s Free Energy Principleโand repeating the exact mistake we made with backpropagation decades ago.
