Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] figure 1 A schematic diagram of the domain-adaptive deep learning training process of the embodiment of the present invention is given. The method mainly includes the following steps:

[0022] Step 1: Rotate and transform the target domain image to obtain a self-supervised learning training sample set;

[0023] Step 2: Jointly train the converted self-supervised learning training sample set and source domain training samples to obtain a deep learning model.

[0024] Step 3: Use the model obtained from the above joint training for the vision task T on the target domain.

[0025] In step 1, the target domain image is rotated and transformed to obtain a training sample set for self-supervised learning. The process first rotates the target domain image by 0°, 90° and 180° respectively, and the three rotation angles correspond to category labels 0, 1 an...

Abstract

The invention discloses a domain self-adaptive deep learning method, which comprises the following steps of: carrying out rotation transformation on a target domain image to obtain a self-supervised learning training sample set; And carrying out joint training on the converted self-supervised learning training sample set and the source domain training sample set to obtain a domain adaptive deep learning model used for a visual task on a target domain. According to the method, a target domain sample does not need to be labeled, the feature representation of the target domain can be effectivelylearned, and the performance of a computer vision task on the target domain is improved. The invention further discloses a domain self-adaptive deep learning readable storage medium which also has theabove beneficial effects.

Description

technical field [0001] The invention relates to the field of domain-adaptive deep learning, in particular to a domain-adaptive deep learning method and a readable storage medium for computer vision tasks. Background technique [0002] Models such as image classification, image semantic segmentation, object recognition, and object detection in computer vision tasks are usually obtained through supervised learning training. Supervised learning, especially supervised learning based on deep neural networks, usually requires a large number of labeled training samples. The labeling of these samples requires a lot of manpower and material resources. For example, image segmentation requires pixel-by-pixel semantic labeling, which is very difficult and costly. After the model is trained on the labeled data, it is applied to the test data. Supervised learning is a very effective method when the test data has the same distribution as the training data. However, in practical applicat...
