DDPM adopts the sinusoidal positional encoding from the Transformer, converting the time step t into a high-dimensional vector, then mapping it through two fully connected layers to a dimension matching the number of feature map channels, and finally modulating the features of each layer by element-wise addition or FiLM.

UnverifiedIn the diffusion model, the time step t is converted into a vector via sine-cosine encoding similar to Transformer positional encoding, and then fused with the image features.70% similarVerifiedThe autoregressive generation characteristic of LLMs determines that their output is streamed token by token, stemming from the decoding strategy of the Transformer architecture.66% similarVerifiedModern time series foundation models typically adopt improved Transformer architectures, modeling temporal and variable dimension dependencies separately through decoupled attention mechanisms or channel mixing modules66% similarUnverifiedThe second stage of NCM uses a Transformer to predict the discrete codes at each level in parallel, and the prediction at each level is conditioned on the previous level.66% similarUnverifiedThe original DDPM sets the variance of the reverse process to a fixed value, but later improved versions allow the variance to be learned as well.65% similar
