Embodiment Construction

[0046] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] The invention provides a fine-grained classification method. refer to figure 1 As shown, it is a schematic flowchart of a fine-grained classification method provided by an embodiment of the present invention. The method may be performed by a device, and the device may be implemented by software and / or hardware.

[0048] In this embodiment, the fine-grained classification method includes:

[0049] S110: Construct an initial model and acquire an original image, and perform preprocessing on the original image to form training data for training the initial model.

[0050] Specifically, the process of preprocessing the original image to form the training data for training the initial model includes:

[0051] First, the original image is fed into the initial model to obtain the saliency matrix corresponding to th...

Abstract

The invention relates to artificial intelligence, and discloses a fine-grained classification method, which comprises the following steps of creating an initial model, acquiring an original image, andpreprocessing the original image to form training data for training the initial model; acquiring loss data corresponding to the original image based on the initial model and the training data; performing random gradient descent back propagation based on the loss data until the initial model is converged within a preset range to form classification model training; and performing classification prediction on the to-be-processed image through the classification model. The invention also relates to a blockchain technology, and the original image is stored in the blockchain. According to the method, the local feature region can be adaptively selected, and the classification prediction accuracy is improved.

Description

technical field [0001] The present invention relates to artificial intelligence, in particular to a fine-grained classification method, device, electronic equipment and computer-readable storage medium. Background technique [0002] Fine-grained classification mainly refers to dividing the basic categories into finer subcategories, such as distinguishing the types of birds and the styles of cars. Currently, it has a wide range of business needs and application scenarios in the industry and in real life. [0003] Currently, fine-grained classification methods mainly include two categories. One is to classify by locating local feature regions and extracting these image features that can distinguish between different categories of regions. However, since there is no location labeling information of local key regions, most algorithms use pre-set size windows to select local feature regions. It can be seen that this method cannot automatically adapt to the size of the feature a...
