Message definition (Diffusion Models Are Real-Time Game Engines)

where <math>T = {\{ o_{i \leq n},a_{i \leq n}\}} \sim \mathcal{T}_{agent}</math>, <math>x_{0} = {\phi{(o_{n})}}</math>, <math>t \sim {\mathcal{U}{(0,1)}}</math>, <math>\epsilon \sim {\mathcal{N}{(0,\mathbf{I})}}</math>, <math>x_{t} = {{\sqrt{{\overline{\alpha}}_{t}}x_{0}} + {\sqrt{1 - {\overline{\alpha}}_{t}}\epsilon}}</math>, <math>{v{(\epsilon,x_{0},t)}} = {{\sqrt{{\overline{\alpha}}_{t}}\epsilon} - {\sqrt{1 - {\overline{\alpha}}_{t}}x_{0}}}</math>, and <math>v_{\theta^{\prime}}</math> is the v-prediction output of the model <math>f_{\theta}</math>. The noise schedule <math>{\overline{\alpha}}_{t}</math> is linear, similarly to Rombach et al. ([https://arxiv.org/html/2408.14837v1#bib.bib26 2022]).

其中 Failed to parse (syntax error): {\displaystyle T = {\{ o_{i \leq n},a_{i \leq n}\}} \sim \mathcal{T}_{代理}} ， $x_{0}=\phi {(o_{n})}$ ， $t\sim {\mathcal {U}}{(0,1)}$ ， $\epsilon \sim {\mathcal {N}}{(0,\mathbf {I} )}$ ， $x_{t}={{\sqrt {{\overline {\alpha }}_{t}}}x_{0}+{\sqrt {1-{\overline {\alpha }}_{t}}}\epsilon }$ ， $v{(\epsilon ,x_{0},t)}={{\sqrt {{\overline {\alpha }}_{t}}}\epsilon -{\sqrt {1-{\overline {\alpha }}_{t}}}x_{0}}$ ，而 $v_{\theta ^{\prime }}$ 是模型 $f_{\theta }$ 的 v预测输出。噪声调度 ${\overline {\alpha }}_{t}$ 是线性的，与 Rombach 等（2022）类似。
