AI summary

Technology as described herein provides for generating an image via a generator network, including extracting structural relationship information from a text prompt, wherein the structural relationship information includes sentence features and token features, generating encoded text features based on the sentence features and on relation-related tokens, wherein the relation-related tokens are identified based on parsing text dependency information in the token features, and generating an output image based on combining, via self attention and cross-attention layers, the encoded text features and encoded image features from an input image canvas. Embodiments further include applying a gating function to modify image features based on text features. The self attention and cross-attention layers can be applied via a cross-modality network, the gating function can be applied via a residual gating network, and the relation-related tokens can be further identified via an attention matrix.
