The invention discloses a complex three-dimensional scene twinborn modeling method guided by a geographic knowledge map, belongs to the technical field of digital twinborn, and solves the problems that the existing twinborn scene modeling method mostly focuses on single space dimension fusion and does not consider the multi-dimension fusion requirement, such as the synergistic effect of objects, attributes and the whole scene is not considered, and the modeling effect is poor. The model precision is reduced, and the adaptability is insufficient. The method comprises the following steps: constructing a scene-feature-transition complex three-dimensional scene geographic knowledge graph based on obtained dynamic and static data of each geographic scene in a complex three-dimensional twinborn scene physical space, and updating in real time; and carrying out dynamic fusion modeling on the complex three-dimensional scene through progressive guidance layer by layer from an object level, an attribute level to a scene level by adopting a geographic knowledge graph of the complex three-dimensional scene. The method is used for complex three-dimensional scene twin modeling.

The application discloses a clustering-guided infrared small target hierarchical structure texture fusion segmentation method, which comprises the following steps: constructing an infrared small target segmentation data set; constructing an initial infrared small target segmentation network model; inputting a training set into the model for training to obtain an infrared small target segmentation network model; inputting a test set or an infrared small target image to be segmented into the infrared small target segmentation network model to output an infrared small target segmentation result, and the like. The application provides a small target segmentation deep learning method for an infrared small target image, which combines image clustering results to perform a composition strategy, integrates image prior structure information in an initial composition stage, effectively extracts infrared image structure information through a graph feature learning module, learns a global-local hierarchical structure relationship of the image, effectively fuses infrared image structure information and texture information through feature pyramid fusion, deepens overall scene cognition of the infrared image, and makes the algorithm more robust.

The invention relates to the technical field of application of artificial intelligence in assisted reproduction technology, and discloses an assisted reproduction multi-node clinical decision-making method based on machine learning. The method comprises the following steps: collecting sample data, obtaining sample features, and carrying out conversion and interpolation on the sample features; performing predictive variable screening on the sample features by using a Spearman correlation coefficient; dividing the data of the complete sample into a training set, a test set and a verification set according to a sample proportion of 8: 1: 1, taking a predicted variable obtained by screening as an independent variable in the training set, and taking accumulated live birth within 2 years after single egg taking as a dependent variable; respectively constructing prediction models in different decisions of four stages of a controlled ovarian stimulation scheme, a gonadotropin initiation amount and the like, and correcting to obtain prediction values; and carrying out hyper-parameter adjustment by using the test set, and comparing live birth outcomes of the crowds which accord with and do not accord with the recommendation by using the verification set. According to the method, corresponding cumulative live yield prediction can be provided for various feasible schemes, and a single optimal path is not recommended.

A dangerous water flow simulation device includes a first ramp and a first observation box, with the height difference at the outlet creating a tumbling flow. A second ramp and the second observation box are equipped with baffles, which generate vortex flows upon impact. Various obstacles are placed on the ramp, including triangular obstacles, cylindrical obstacles, left and right obstacles, angled and flat obstacles, and bottom obstacles. The triangular obstacles create an inverted V-shaped flow, the cylindrical obstacles create a smiling flow, the gap between the left and right obstacles creates a positive V-shaped flow, the angled and flat obstacles create a frowning flow, and the bottom obstacles generate bubbles. This invention simulates various dangerous water flows through the observation box, ramp, and obstacles, allowing firefighters to visually observe flow characteristics in a safe environment, improving rescue judgment and emergency response capabilities. It is suitable for water rescue training and educational demonstrations.
