  • Patent number: 12705433
    Abstract: Methods, systems, apparatuses, devices, and computer program products are described. A flow generation service may receive a natural language input that indicates instructions for automating a task according to a first process flow. Using a large language model (LLM), the flow generation service may decompose the natural language input into a set of elements (e.g., logical actions) and connectors, where the LLM may be trained on first metadata corresponding to a second process flow that is created manually by a user. In addition, using the LLM, the flow generation service may generate second metadata corresponding to each of the set of elements based on decomposing the natural language input. The flow generation service may sequence and merge the set of elements to generate the first process flow. In some examples, the flow generation service may send, for display to a user interface of a user device, the first process flow.

  • Publication number: 20260141697
    Abstract: A training framework includes a transparent and unbiased dataset generation pipeline to generate unbiased multi-modal training data for training a multi-modal LLM. Specifically, one or more images may be annotated using image recognition models, e.g., for object detection, attributes, relations, segmentation, etc. Then, the generated annotations are used to generate scene graph. A scene graph is a data structure that represents objects with attributes in an image as nodes and relationships between objects in an image as edges. Several computer programs are then used to systematically generate question-answer pairs. Because the computer programs include a set of known rules, how the data is generated is known explicitly and thus transparent. The question-answer pairs may be of several types, e.g., a type associated with each of the types of image recognition models. The question-answer pairs may be included in a training dataset and used to train a multimodal LLM.

  • Patent number: 12585919
    Abstract: Embodiments described herein provide a mechanism for replacing existing text encoders in text-to-image generation models with more powerful pre-trained language models. Specifically, a translation network is trained to map features from the pre-trained language model output into the space of the target text encoder. The training preserves the rich structure of the pre-trained language model while allowing it to operate within the text-to-image generation model. The resulting modularized text-to-image model receives prompt and generates an image representing the features contained in the prompt.

  • Publication number: 20260044993
    Abstract: Embodiments described herein provide a generation model comprising a video-specific variational auto-encoder (VAE) for effective compression of video pixel information with reduced spatial and temporal dimensions and a video diffusion transformer (vDiT) to generate latent representations of frames. Specifically, the VAE may, instead of encoding each frame independently, incorporate both temporal and spatial compression. This significantly decreases the token length, improves the computational cost of training and inference, and facilitates the generation of long videos. The encoded training video, in the form of latent representations from a VAE encoder may then be passed to the vDiT to reconstruct the latent representations during training. The trained vDiT may then generate latent representations of a video in response to a text input, and the latent representations may be converted to a video output by a VAE decoder.

  • Patent number: 12547946
    Abstract: Embodiments described a field extraction system that does not require field-level annotations for training. Specifically, the training process is bootstrapped by mining pseudo-labels from unlabeled forms using simple rules. Then, a transformer-based structure is used to model interactions between text tokens in the input form and predict a field tag for each token accordingly. The pseudo-labels are used to supervise the transformer training. As the pseudo-labels are noisy, a refinement module that contains a sequence of branches is used to refine the pseudo-labels. Each of the refinement branches conducts field tagging and generates refined labels. At each stage, a branch is optimized by the labels ensembled from all previous branches to reduce label noise.
