AI Technical Summary

Problems solved by technology

However, deep learning models are very vulnerable to human-crafted input perturbations, i.e. adversarial attacks
The pervasiveness of this deep learning vulnerability has drawn widespread attention because the perturbation is imperceptible to humans, yet highly damaging to today's artificial intelligence systems

Abstract

The invention provides a method and device for generating an adversarial sample, electronic equipment and a medium, and relates to the technical field of artificial intelligence, in particular to the technical field of behavior recognition, adversarial defense training and the like. According to the implementation scheme, a first human skeleton formed by connecting a plurality of joint nodes and corresponding skeleton data are obtained, and the skeleton data comprise first rectangular coordinate representation of the first human skeleton in a preset rectangular coordinate system; determining a rectangular coordinate value of a root node in the plurality of joint nodes based on the first rectangular coordinate representation; constructing a spherical coordinate system based on the first human skeleton; determining a spherical coordinate value corresponding to each joint node in other joint nodes except the root node in the plurality of joint nodes in a spherical coordinate system; and applying an interference value to the angle of the bone in the first human skeleton, and determining an adversarial sample based on the applied interference value and the corresponding spherical coordinate value of each of the other joint nodes in the spherical coordinate system.

Description

Technical field [0001] This openness involves the field of artificial intelligence technology, especially involving technological fields such as behavior recognition and confrontation with defense training. It specifically involves a method, device, electronic equipment, computer readable storage medium and computer program products that generate against samples. Background technique [0002] Artificial intelligence is a discipline that enables some thinking processes and intelligent behaviors (such as learning, reasoning, thinking, planning, etc.) to simulate computers. It has both hardware -level technology and software -level technologies. Artificial intelligence hardware technology generally includes technologies such as sensors, special artificial intelligence chips, cloud computing, distributed storage, and big data processing. Artificial intelligence software technology mainly includes computer vision technology, voice recognition technology, natural language processing te...
