Abstract: A method and device for harmony-aware audio-driven motion synthesis are provided. The method includes determining a plurality of testing meter units according to an input audio, each testing meter unit corresponding to an input audio sequence of the input audio, obtaining an auditory input corresponding to each testing meter unit, obtaining an initial pose of each testing meter unit as a visual input based on a visual motion sequence synthesized for a previous testing meter unit, and automatically generating a harmony-aware motion sequence corresponding to the input audio using a generator of a generative adversarial network (GAN) model. The GAN model is trained by incorporating a hybrid loss function. The hybrid loss function includes a multi-space pose loss, a harmony loss, and a GAN loss.

Abstract: A method for cleaning an air conditioner comprises: in response to a cleaning instruction, controlling frosting on the surface of a target heat exchanger; after a frosting completion condition is met, controlling defrosting of the frost on the target heat exchanger; and after a defrosting completion condition is met, reducing the surface temperature of the target heat exchanger to a sterilization temperature, and carrying out quick cooling sterilization, wherein the temperature difference between the sterilization temperature and the defrosting temperature during defrosting meets a set temperature change sterilization condition. By means of a frosting-defrosting process, dirt such as dust on the heat exchanger may be effectively stripped and deep bacteria may be exposed, and then the quick cooling sterilization process may kill the bacteria by utilizing the sharp temperature change during switching from the defrosting process to the quick cooling process. Also disclosed is the air conditioner.

Abstract: 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. The system determines the intent of the sentence based on the confidence scores of the sentence and the modified sentence. The system performs tasks based on the determined intent and performs conversations with users based on the tasks.
