4results about How to "High fine-tuning precision" patented technology

The invention relates to the technical field of artificial intelligence, and discloses a model fine tuning method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a knowledge document of a target domain; extracting question and answer pairs in the knowledge document to obtain a question and answer pair set in the knowledge document; determining a quality score of each question and answer pair according to the text information of each question and answer pair in the question and answer pair set; according to the quality score of each question and answer pair, screening a target question and answer pair from the question and answer pair set, and taking the target question and answer pair as a fine tuning training sample of the to-be-fine-tuned model; and based on the fine tuning training sample, performing fine tuning optimization on the to-be-fine-tuned model to obtain a target model. According to the method provided by the scheme, the domain classification is performed on the knowledge document, and the target question and answer pair which can be used as the fine tuning training sample is screened according to the quality score of the question and answer pair, so that the quality of the fine tuning training sample is improved, deviation of the model in the fine tuning process is avoided, and the fine tuning precision of the model is improved.

The invention discloses an anesthesia puncture outfit for a surgical patient, and relates to the technical field of anesthesia puncture outfit, the anesthesia puncture outfit comprises a puncture handpiece, the puncture handpiece is provided with a puncture needle sheath; an anesthesia administration part is mounted on the puncture handpiece; the anesthesia administration part is used for sliding on the puncture needle sheath piece; the puncture needle sheath piece is used for guiding the anesthesia administration part; a bubble removing guide piece is mounted on the puncture handpiece; the bubble removing guide piece is used for exhausting; a sampling sealing piece is mounted on the defoaming guide piece; the anesthesia administration part can be matched with a puncture needle sheath piece, a doctor can conveniently and rapidly conduct puncture anesthesia work, the structure is easy to operate, the doctor can more conveniently locate the arachnoid, the accuracy of medicine injection of the subarachnoid space is guaranteed, and the problems that an existing anesthesia puncture outfit for a surgical patient is inconvenient to prompt the doctor to penetrate through the subarachnoid space, and the working efficiency is high are solved. And excessive puncture is easily caused.

The application provides a precision calibration detection instrument, which comprises a test table, a sleeve spindle, a height adjustment assembly in threaded transmission connection with the upper end of the sleeve spindle, and a swing fine adjustment assembly in eccentric lever mode hinged in the sleeve spindle; the swing fine adjustment assembly forms a non-equal force arm lever structure with the pivot as a fulcrum, and converts the linear adjustment displacement of the upper end into the micron-level angular displacement fine adjustment of the test table of the lower end, so that the technical problem that the existing devices mostly adopt direct translation type fine adjustment, the adjustment precision can only reach 0.01mm level, and the sub-micron level precision measurement requirement cannot be met is solved.

The utility model belongs to the technical field of detection, and discloses a height and rotation angle adjustable electron microscope sample clamp which comprises a support, a base connected to the support, a spherical groove formed in the base, a spherical connecting block connected in the spherical groove in a spherical mode, and a first threaded sleeve connected in the spherical connecting block in a penetrating mode. According to the scheme, the base is provided with the spherical groove and the spherical connecting block to form an adjustable spherical connecting mechanism, and the adjustable spherical connecting mechanism is matched with the first threaded sleeve penetrating through the sphere center and the adjusting rod extending long, so that precise adjustment of the height and the rotating angle of the objective table is achieved, and the fine adjustment precision is improved through the leverage effect of the adjusting rod; the problem of unstable adjustment caused by too short lever arm of a traditional structure is effectively solved; meanwhile, the adjusting rod with anti-skid lines at the bottom end and the liftable positioning block facilitate rapid positioning and resetting, the whole clamp is compact in structure and convenient and fast to operate, and the requirements for multiple angles, height fine adjustment and high stability of sample morphology observation and energy spectrum analysis under the electron microscope can be met.
