Embodiment Construction

[0057] Such as figure 1 , 2 As shown, the method for small sample image recognition based on deep learning of the present invention includes the following steps: 1. Divide the training set; 2. Generate noisy images; 3. Pre-train the prototype space discrimination network; 4. Train the deception image generation network; 5. , Training the prototype space discriminant network; 6. Repeat steps 4 and 5 for cross iteration training until the preset number of iterations is reached or the accuracy is no longer improved; 7. Image category recognition.

[0058] One, divide the training set

[0059] The sample images in the training set are randomly divided into support set S and query set Q. The number of sample images in each category in the training set is generally not less than 600; among them, the support set Indicates that the support set S contains sample images of n categories, where To support the collection of sample images belonging to category k in the set S, Is the mth sampl...

Abstract

The invention relates to a small sample image recognition method based on deep learning. The method comprises the following steps of 1, dividing a training set; 2, generating a noise image; 3, pre-training a prototype space discrimination network; 4, training a deception image generation network; 5, training a prototype space discrimination network; 6, repeating the step 4 and the step 5 for crossiteration training until preset iteration times are reached or the accuracy is not improved any more; 7, performing image category recognition. According to the method, on the premise that a trainedmodel is not changed, by means of a few labeled samples of each class, through generalization of the rare classes, new classes which are not seen in the training process are recognized, extra trainingis not needed, and the image recognition accuracy is high.

Description

Technical field [0001] The invention belongs to the technical field of image recognition, and relates to a small sample image recognition method based on deep learning. More specifically, the present invention relates to a deep learning small sample image recognition method based on the idea of ​​generating confrontation networks and prototypes. Background technique [0002] Deep learning has been widely used in various fields to solve various problems, such as image recognition problems, which can often achieve high accuracy. However, deep learning is a "data-hungry" technology that requires a large number of labeled samples to function. But in reality, many problems are that there are not so many annotated images, and the cost of obtaining annotated images is also very high, such as in the medical field and security field. With the emergence of more application scenarios, we are increasingly facing the problem of insufficient sample numbers. Therefore, when the amount of anno...
