Abstract: The present disclosure provides a method and device for constructing an autism spectrum disorder (ASD) risk prediction model. The method includes: establishing a first data table and a second data table based on case information of a sample set, obtaining a first grouped table set and a second grouped table set according to a preset characteristic arrangement rule and marker grouping rule, training data based on a random forest machine learning algorithm, and importing test data to obtain a first best characteristic combination and a second characteristic combination; and obtaining a first model based on the first best characteristic combination, stratified sampling of the first data table, and the random forest machine learning algorithm, obtaining a second model based on the second best characteristic combination, stratified sampling of the second data table, and the random forest machine learning algorithm, and performing combination to construct an ASD risk prediction model.

Abstract: An unmanned aerial vehicle aerial vehicle and a localization method for an unmanned aerial vehicle aerial vehicle are described. In an embodiment, an unmanned aerial vehicle comprises: a first ultra-wide band node; a second ultra-wide band node; and a localization processor configured to use signals received at the first ultra-wide band node and the second ultra-wide band node from a plurality of anchor nodes located within an environment to estimate a pose state of the unmanned aerial vehicle, wherein the first ultra-wide band node and the second ultra-wide band node are arranged on the unmanned aerial vehicle at positions offset from one another.

Abstract: This invention comprises a control device and a communication port device applied to drone, and a drone using such devices. The control device comprises a carrier board and a main control board that is detachably configured on the carrier board, said main control board is electrically connected with the carrier board, and the carrier board is configured with an interface device in which connections between a plurality of kinds of external devices with said carrier board are established. The carrier board is mainly used for connection with other external electronic devices and power distribution, and the main control board is responsible for processing sensor data and delivering control information. The main control board and the carrier board are connected through a single interface to enable a data transmission. The communication port device is configured on the drone flight controller.
