  • Patent number: 11989941
    Abstract: Embodiments described a method of video-text pre-learning to effectively learn cross-modal representations from sparse video frames and text. Specifically, an align and prompt framework provides a video and language pre-training framework that encodes the frames and text independently using a transformer-based video encoder and a text encoder. A multi-modal encoder is then employed to capture cross-modal interaction between a plurality of video frames and a plurality of texts. The pre-training includes a prompting entity modeling that enables the model to capture fine-grained region-entity alignment.

  • Publication number: 20240161369
    Abstract: Embodiments described herein provide systems and methods of subject-driven image generation. In at least one embodiment, a system receives, via a data interface, an image containing a subject, a text description of the subject in the image, and a text prompt relating to a different rendition of the subject. The system encodes, via an image encoder, the image into an image feature vector. The system encodes, via a text encoder, the text description int a text feature vector. The system generates, by a multimodal encoder, a vector representation of the subject based on the image feature vector and the text feature vector. The system generates, by a neural network based image generation model, an output image based on an input combining the text prompt and the vector representation.

  • Publication number: 20240105821
    Abstract: A structure of a two-dimensional material-based device having an air-gap and a method for preparing same comprises a substrate, a gate, an dielectric, a two-dimensional material-based film, and source and drain electrodes; the air-gap is formed between the two-dimensional material-based film and the side wall of the dielectric on the gate, or the air-gap is formed between the dielectric and the gate; two-dimensional material-based devices of the above structure utilize the ductility and flexibility of two-dimensional materials to reduce the coupling between the gate and the source/drain electrodes, thereby reducing the parasitic capacitance and the circuit delay; also, the structure ensures that a part of the contact region of the source and drain electrodes with the two-dimensional material can be controlled by the gate, and can thus avoid the reduction in electrical properties and keep a low resistance of the device.
