Hossenfelder by Robin Hanson – Hanson’s recent article criticizing fundamental physics approvingly discussed Sabine Hossenfelder book ‘Lost in Math’. Sabine posted an initial comment that was fairly confrontational toward Hanson. However the two rapidly converged and quickly begun a positive dialogue. In particular they both agree that funding science via betting norms is a reasonable idea. Sabine wrote a blog post about the idea.
Player Vs Character: A Two Level Model Of Ethics by Sarah Constantin – A two level model of human behavior: Your personality and abilities are mapped to your deck in games like magic the gathering, what you do with your traits is mapped to in-game decisions. Sarah then discusses the implications of this model for morality.
Science Of AI by Open AI – ‘We’ve discovered that the gradient noise scale, a simple statistical metric, predicts the parallelizability of neural network training on a wide range of tasks. Since complex tasks tend to have noisier gradients, increasingly large batch sizes are likely to become useful in the future, removing one potential limit to further growth of AI systems. More broadly, these results show that neural network training need not be considered a mysterious art, but can be rigorized and systematized.’
