同样地,本文对adaLN block的设计做了同样的处理,除了回归 \gamma 和\beta 外,DiT还回归了维度缩放参数 \alpha ,这些参数应用在DiT block内的残差连接之前。 1.3 Transformer decoder 经过最后一个DiT block之后,需要将向量序列解码成噪声预测和协方差预测,这里使用了一个线性解码器来完成这一操作,将每一个向量变为...
a text-to-image model based on the earlier results of PixArt-α (Alpha) andPixArt-δ (Delta), which offers improved image quality, prompt accuracy and efficiency in handling training data. Its unique feature is the superior resolution of the images generated by the ...
In this paper, we introduce PixArt - Σ \\Sigma , a Diffusion Transformer model(DiT) capable of directly generating images at 4K resolution. PixArt - Σ \\Sigma represents a significant advancement over its predecessor, PixArt - α \\alpha , offering images of markedly higher fidelity and ...
