Mannequin Structure

The fashions use the diffusion transformer structure with self-attention, cross-attention, and feedforward layers for denoising video within the latent house. It’s attainable for the mannequin to situation on textual content enter as a result of cross-attention, and the time data is embedded utilizing adaptive layer normalization. Inputs of picture or video are added by concatenating their latent frames with the generated frames.

The mannequin follows a Transformer-based Diffusion Mannequin method for video denoising in latent house. Right here’s a step-by-step breakdown:

Tokenization and Latent Area Processing

• The enter video is first encoded utilizing Cosmos-1.0-Tokenizer-CV8x8x8, changing it right into a set of latent tokens.
• These tokens are then corrupted with Gaussian noise, making them partially degraded.
• A 3D Patchification step processes these tokens into non-overlapping 3D cubes, which function the enter for the transformer community.

Transformer-Primarily based Denoising Community

The mannequin applies N blocks of:

• Self-Consideration (for intra-frame and inter-frame relationships)
• Cross-Consideration (to situation on textual content enter)
• Feedforward MLP layers (to refine the denoising course of)

Every block is modulated utilizing adaptive layer normalization (AdaLN-LoRA), which helps stabilize coaching and enhance effectivity.

a. Self-Consideration (Understanding Spatiotemporal Relations)

• Self-attention is utilized to the spatiotemporal latent tokens.
• It helps the mannequin perceive relationships between totally different video patches (each inside frames and throughout frames).
• This ensures that objects and movement stay constant throughout time.

b. Cross-Consideration (Conditioning on Textual content Prompts)

• Cross-attention layers combine the T5-XXL textual content embeddings as keys and values.
• This enables the mannequin to align the generated video with the textual content description, making certain semantic relevance.

c. Question-Key Normalization

• The paper mentions query-key normalization utilizing RMSNorm.
• This helps forestall coaching instability the place consideration logits explode, making certain easy coaching.

d. MLP (Feedforward) Layers for Characteristic Refinement

• The MLP layers refine the denoised tokens.
• They apply extra transformations to enhance readability, texture particulars, and take away high-frequency noise.

Positional Embeddings for Temporal Consciousness

The mannequin makes use of 3D Rotary Place Embedding (3D RoPE) to embed positional data throughout:

• Temporal axis (time steps)
• Peak axis (spatial dimension)
• Width axis (spatial dimension)

FPS-aware scaling is utilized, making certain the mannequin generalizes to totally different body charges.

Low-Rank Adaptation (AdaLN-LoRA)

• The mannequin applies LoRA (Low-Rank Adaptation) to adaptive layer normalization (AdaLN).
• This considerably reduces mannequin parameters (from 11B to 7B) whereas sustaining efficiency.

Ultimate Reconstruction

• After N transformer layers, the denoised latent tokens are handed to the decoder of Cosmos-1.0-Tokenizer-CV8x8x8.
• The decoder converts the denoised tokens again right into a video.

Enter and Output

• Text2World Enter: A textual content string (beneath 300 phrases) describing the specified scene, objects, actions, and background.
• Text2World Output: A 5-second MP4 video visualizing the textual content description.
• Video2World Enter: A textual content string (beneath 300 phrases) and a picture (or the primary 9 frames of a video) with a decision of 1280×704.
• Video2World Output: A 5-second MP4 video, utilizing the offered picture/video as a place to begin and visualizing the textual content description for the following frames.
