  • Publication number: 20260076727
    Abstract: A split-type ablation needle connected to a cryoablation device comprising a needle arranged at a distal end of the split-type ablation needle; a tube body connected to the needle, wherein two second channels used for delivering a medium to the needle and delivering the medium returned from the needle respectively, and an insulation structure circumferentially wrapping the exterior of the two second channels, are provided inside the tube body; and a second-type joint, comprising a second connector and a second cavity. The split-type ablation needle is enable to be disassembled from the cryoablation device for puncture only, thereby reducing the impact of the tail weight of the split-type ablation needle on the puncture process.

  • Patent number: 12468897
    Abstract: Aspects of the disclosure are directed to automatically selecting examples in a prompt for an LLM to demonstrate how to perform tasks. Aspects of the disclosure can select and build a set of examples from LLM zero-shot outputs via predetermined criteria that can combine consistency, diversity, and repetition. In the zero-shot setting for three different LLMs, using only LLM predictions, aspects of the disclosure can improve performance up to 15% compared to zero-shot baselines and can match or exceed few-shot base-lines for a range of reasoning tasks.

  • Publication number: 20240394545
    Abstract: Aspects of the disclosure are directed to methods, systems, and computer readable media for universal self-adaptive prompting (USP), which includes an automatic prompt design approach specifically tailored for zero-shot learning, though still compatible with few-shot learning. To achieve universal prompting, USP categorizes a natural language processing (NLP) task into one of a plurality of possible task types and then uses a corresponding selector to select the most suitable queries and zero-shot model-generated responses as pseudo-demonstrations, thereby generalizing in-context learning to the zero-shot setup in a fully automated manner.

  • Publication number: 20240311651
    Abstract: Disclosed is a method for searching for a neural network architecture ensemble model. The method includes: obtaining a dataset, where the dataset includes a sample and an annotation in a classification task; performing search by using a distributional neural network architecture search algorithm, including: determining a hyperparameter of a neural network architecture distribution; sampling a valid neural network architecture from the architecture distribution defined by the hyperparameter; training and evaluating the neural network architecture on the dataset, to obtain a performance indicator; determining, based on the performance indicator, neural network architecture distributions that share the hyperparameter, to obtain a candidate pool of base learners; and determining a surrogate model; and predicting test performance of the base learner in the candidate pool by using the surrogate model, and determining that k diverse base learners that meet a task scenario requirement form an ensemble model.

  • Publication number: 20240232575
    Abstract: A neural network obtaining method, a data processing method, and a related device are disclosed. The disclosed methods may be used in the field of automatic neural architecture search technologies in the field of artificial intelligence. An example method includes: obtaining first indication information, where the first indication information indicates a probability and/or a quantity of times that k neural network modules appear in a first neural architecture cell; generating the first neural architecture cell based on the first indication information, and generating a first neural network; obtaining a target score corresponding to the first indication information, where the target score indicates performance of the first neural network; and obtaining second indication information from a plurality of pieces of first indication information based on a plurality of target scores, and obtaining a target neural network corresponding to the second indication information.
