But unless you&#39;re a graphics or physics engine programming specialist, it&#39;s all wrapped behind an API, so you don&#39;t actually have to know the details of how they work. <br/><br/>All that&#39;s needed these days is forming an intuition for how the various exposed function APIs work for representing rotations and spherical lerp. Hmm, I guess this is true for matrices as well. 2025-08-04T19:38:00Z https://yabu.me/nevent1qqsgg4f2enmfy6fvqeunjxpkm6xww0yf8qq5yn72d4mc30anpv66k3gzyqgl0jdr3jsxr8fy0ykwdh6l76s8day367ysg7p8tlysrzeuwezcvc8rk4v In reply to <a href='/nevent1qqstmyfyd6yzscqvr3u7p5wlcwm3sm76uqv38jnw9cf0j5uvunm6xggzrymmx'>nevent1q…ymmx</a><br/>_________________________<br/><br/>Ah, another interesting path to Hamilton-Jacobi as the classical limit is via Maslov dequantization. 2025-07-16T18:41:06Z https://yabu.me/nevent1qqsx9wt6ca6kr50cdw9kgl5j4yewzewxw6v69c8zspjj4vgealaahtszyqgl0jdr3jsxr8fy0ykwdh6l76s8day367ysg7p8tlysrzeuwezcvj2k7tn In reply to <a href='/nevent1qqsdcjhaedhuv5ufynd4pqpl676ggr4e8yak239glmt9pu6362xcfzqguehyt'>nevent1q…ehyt</a><br/>_________________________<br/><br/>I think that phrasing is ambiguous enough for anyone to paint as they like. <br/><br/>It&#39;s likely referring to using reinforcement learning instead of trying to imitate some example data, to improve coherence (and in particular, the step that went directly from the raw model that computes conditional probs of strings--which we can sample from and talk to by conditioning on a conversation prefix--based on internet data, straight to RL without adjustments to give response strings more in line with human conversational expectations). <br/><br/>I can see why the author would want to phrase it that way for a broader audience. The optimization phase has much less hand-holding direction than typical. It is kind of a misleading way to put it though. 2025-01-25T21:04:01Z https://yabu.me/nevent1qqsqhahqndxs2xlazq4z3yv4vmeyykvv73sv3tmy750kp57drkhkdyszyqgl0jdr3jsxr8fy0ykwdh6l76s8day367ysg7p8tlysrzeuwezcv93603w In reply to <a href='/nevent1qqstdj94tcszr6hkr8kqz5055ufptn0wmr86wjxfwe59jx84rgquwvcut2yl0'>nevent1q…2yl0</a><br/>_________________________<br/><br/>What are your thoughts on the recent timescape model news cycle, if you don&#39;t mind me asking. 2025-01-06T09:14:57Z https://yabu.me/nevent1qqsf8v3x32zhrf8hrsfd2vqjv4m08xxfmhqmjyhm4vude8kvfp5gzwqzyqgl0jdr3jsxr8fy0ykwdh6l76s8day367ysg7p8tlysrzeuwezcvcyfth2 In reply to <a href='/nevent1qqsdfz0am352t5n9s4mgk38cuk6hxx5dqrw9g3f3k6l8vfvhswgrc9sucnjm9'>nevent1q…njm9</a><br/>_________________________<br/><br/>Can you explain the sense in which beyond spacetime is misleading or even nonsense? I&#39;d already read the article and took it as amplituhedron based calculations don&#39;t explicitly refer to spacetime--don&#39;t incorporate space-time coordinates.
