本文介绍了一种名为视觉自回归建模(Visual AutoRegressive modeling,简称VAR)的新型图像生成框架。VAR模型重新定义了图像上的自回归学习,采用从粗到细的“下一尺度预测”方法,与传统的“下一标记预测”方法相比,VAR在图像生成任务上取得了显著的性能提升。VAR模型在ImageNet 256×256基准测试中,不仅在Fréchet inception...
Visual Autoregressive Modeling (VAR) 是一种全新的视觉生成模式,它创造性地调整了图像上的自回归学习 (AR) 预测模式,即从分区标记改为全局下一尺度 (next-scale),这种简单直观的方法使得自回归变换器能够快速学习图像的视觉分布并良好泛化。通过实验比较,这种类 GPT 风格的图像生成自回归模型的效果完全超越了当下流...

For the case of autoregressive modeling, the intention is to determine an all-pole IIR filter, that when excited with white noise produces a signal with the same statistics as the autoregressive process that we are trying to model. Generate an AR Signal using an All-Pole Filter with White No...
The combination of Kalman filtering in estimating AR parameters produces the methodology of Adaptive Autoregressive (AAR) modeling. EEG signals have been modeled for BCI by the AAR process whose parameters are extracted using the Kalman filter [184]. However, since the EEG signal is noisy and ...

We will now turn our attention toautoregressive models—a family of models that simplify the generative modeling problem by treating it as a sequential process. Autoregressive models condition predictions on previous values in the sequence, rather than on a latent random variable. Therefore, they atte...
