Abstract

The invention requests to protect a picture classification method based on deep transfer learning. wherein the domain adaptation at least comprises data of two domains; wherein the domains are respectively a source domain and a target domain; wherein the source domain data is marked sample data, and the source domain data is marked sample data. The method comprises the following steps: 1) a data preparation stage: preparing source domain data and target domain data, The method comprises the steps of (1) establishing a target category set, (2) establishing a feature extraction model, (3) establishing a basic feature extraction model by using ResNet and a self-attention network, (4) establishing a domain confrontation model, and (5) predicting a sample category and a sample domain by using the domain confrontation model. Wherein domain marking is conducted on a source domain sample and a target domain sample, and a loss function based on the sample migration weight is set, and 5, prediction is conducted on target domain data, a category prediction result serves as a final result, the marking cost is reduced, and the purpose of knowledge migration is achieved.

Description

technical field [0001] The invention belongs to the technical field of computer information processing, and specifically relates to the related fields of artificial intelligence and big data processing. Background technique [0002] With the increasing data scale and computing resources, big data processing technology is also experiencing rapid development. As one of the effective tools of big data processing technology, machine learning plays a key role in big data processing technology. Supervised learning is the An important branch of learning, which is characterized by learning that includes label information. In real life, labels for certain tasks are often difficult to obtain, such as image data, which requires a lot of manpower to label. The largest existing label The image data set is ImageNet, which contains 15 million labeled image data. Its labeling task was completed by 48,940 workers from 167 countries in 2 years. Therefore, how to reduce the labeling cost is a ...
