Abstract

The embodiment of the invention discloses a target recognition model training method and device, equipment and a storage medium, and relates to the technical field of artificial intelligence. One specific embodiment of the method comprises the steps: acquiring a training sample set, wherein training samples in the training sample set are labeled target sample images; constructing a first deep convolutional neural network and a second deep convolutional neural network which are different; performing positive and negative sample sampling on the training sample set by using a first deep convolutional neural network and a second deep convolutional neural network to obtain a positive sample set and a negative sample set respectively; and performing cross training on the first deep convolutionalneural network and the second deep convolutional neural network based on the positive sample set and the negative sample set to obtain a target recognition model. According to the embodiment, a weaksupervision target recognition technology based on positive and negative learning is provided, weak supervision learning can be carried out by fully utilizing error annotation samples, and the robustness of the model is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of computers, and specifically to the technical field of artificial intelligence. Background technique [0002] Object recognition technology refers to the technology of identifying or comparing objects from images or videos. With the development of artificial intelligence, target recognition is a popular direction of computer vision and digital image processing, which is widely used in many fields such as finance, security, automatic driving, robot navigation, intelligent video surveillance, etc., which greatly facilitates people's life. [0003] Industrial-grade face recognition technology often relies on supervised learning, among which the more mainstream supervised learning methods are supervised learning methods based on softmax and cross-entropy loss functions and their variants, including AM-softmax, L2-softmax, sphereface, arcface, etc. Supervised learning needs to label...
