Publication number: 20240386623Abstract: Embodiments described herein provide a method of image generation. The method includes a fixed diffusion model, and a trainable diffusion model. The fixed diffusion model may be pretrained on a large training corpus. The trainable diffusion model may be used to control the image generation of the fixed diffusion model by modifying internal representations of the fixed diffusion model. A task instruction may be provided in addition to a text prompt, and the task instruction may guide the trainable diffusion model together with the visual conditions. The visual conditions may be adapted according to the task instruction. During training, a fixed number of task instructions may be used. At inference, unseen task instructions may be used by combining convolutional kernels of the visual condition adapter.Type: ApplicationFiled: September 29, 2023Publication date: November 21, 2024Inventors: Ning YU, Can QIN, Shu ZHANG, Yihao FENG, Xinyi YANG, Ran XU

Publication number: 20240303882Abstract: Embodiments described herein provide a feedback based instructional image editing framework that employs a diffusion process to follow user instruction for image editing. A diffusion model is fine-tuned using a reward model, which may be trained via human annotation. The training of the reward model may be done by having the image editing model output a number of images, which a human annotator ranks based on their alignment with the original image and a given instruction.Type: ApplicationFiled: July 12, 2023Publication date: September 12, 2024Inventors: Shu Zhang, Xinyi Yang, Yihao Feng, Ran Xu, Ning Yu, Chia-Chih Chen

Patent number: 11902221Abstract: A conversation engine performs conversations with users using chatbots customized for performing a set of tasks that can be performed using an online system. The conversation engine loads a chatbot configuration that specifies the behavior of a chatbot including the tasks that can be performed by the chatbot, the types of entities relevant to each task, and so on. The conversation may be voice based and use natural language. The conversation engine may load different chatbot configurations to implement different chatbots. The conversation engine receives a conversation engine configuration that specifies the behavior of the conversation engine across chatbots. The system may be a multi-tenant system that allows customization of the chatbots for each tenant.Type: GrantFiled: September 29, 2020Date of Patent: February 13, 2024Assignee: Salesforce, Inc.Inventors: Xinyi Yang, Tian Xie, Caiming Xiong, Wenhao Liu, Huan Wang, Kazuma Hashimoto, Jin Qu, Feihong Wu, Yingbo Zhou

Patent number: 11769013Abstract: A multi-tenant system performs custom configuration of a tenant-specific chatbot to process and act upon natural language requests. The multi-tenant system configures the tenant-specific chatbots without requiring tenant-specific training. The multi-tenant system providing a user interface for configuring a tenant-specific set of permitted actions. The multi-tenant system determines a set of example phrases for each of the selected permitted actions. The multi-tenant system receives a natural language request from a user and identifies the action that the user wants to perform. The multi-tenant system uses a neural network to compare the natural language request with example phrases to identify an example phrase that matches the natural language request. The multi-tenant system performs the action corresponding to the matching example phrase.Type: GrantFiled: November 11, 2019Date of Patent: September 26, 2023Assignee: Salesforce, Inc.Inventors: Michael Machado, James Douglas Harrison, Caiming Xiong, Xinyi Yang, Thomas Archie Cook, Roojuta Lalani, Jean-Marc Soumet, Karl Ryszard Skucha, Juan Rodriguez, Manju Vijayakumar, Vishal Motwani, Tian Xie, Bryan McCann, Nitish Shirish Keskar, Zhihao Zou, Chitra Gulabrani, Minal Khodani, Adarsha Badarinath, Rohiniben Thakar, Srikanth Kollu, Kevin Schoen, Qiong Liu, Amit Hetawal, Kevin Zhang, Kevin Zhang, Johnson Liu, Rafael Amsili

Patent number: 11763090Abstract: An online system that allows users to interact with it using expressions in natural language form includes an intent inference module allowing it to infer an intent represented by a user expression. The intent inference module has a set of possible intents, along with a small set of example natural language expressions known to represent that intent. When a user interacts with the system using a natural language expression for which the intent is not already known, the intent inference module applies a natural language inference model to compute scores indicating whether the user expression textually entails the various example natural language expressions. Based on the scores, the intent inference module determines an intent that is most applicable for the expression. If an intent cannot be determined with sufficient confidence, the intent inference module may further attempt to determine whether the various example natural language expressions textually entail the user expression.Type: GrantFiled: December 18, 2019Date of Patent: September 19, 2023Assignee: Salesforce, Inc.Inventors: Tian Xie, Kazuma Hashimoto, Xinyi Yang, Caiming Xiong

Patent number: 11651158Abstract: A system performs conversations with users using chatbots customized for performing a set of tasks. The system may be a multi-tenant system that allows customization of the chatbots for each tenant. The system receives a task configuration that maps tasks to entity types and an entity configuration that specifies methods for determining entities of a particular entity type. The system receives a user utterance and determines the intent of the user using an intent detection model, for example, a neural network. The intent represents a task that the user is requesting. The system determines one or more entities corresponding to the task. The system performs tasks based on the determined intent and the entities and performs conversations with users based on the tasks.Type: GrantFiled: August 13, 2020Date of Patent: May 16, 2023Assignee: Salesforce, Inc.Inventors: Xinyi Yang, Tian Xie, Caiming Xiong, Wenhao Liu, Huan Wang, Jin Qu, Soujanya Lanka, Chu Hong Hoi, Xugang Ye, Feihong Wu

Patent number: 11531821Abstract: A system performs conversations with users using chatbots customized for performing a set of tasks. The system may be a multi-tenant system that allows customization of the chatbots for each tenant. The system processes sentences that may include negation or coreferences. The system determines a confidence score for an input sentence using an intent detection model, for example, a neural network. The system modifies the sentence to generate a modified sentence, for example, by removing a negation or by replacing a pronoun with an entity. The system generates a confidence score for the modified sentence using the intent detection model.
