Embodiment 1
[0068] Embodiment 1 of the present invention provides an image labeling method based on multi-label learning. The purpose of multi-label learning is to define a classification model f l :x→R(l=1,2,...,L). f l A larger value means that the instance is more likely to have y l Label. The ranking function rank(·,·) can be transformed from the function f(·): For any y k ∈Y,y j ∈Y(k≠j), if f k (x i ) > f j (x i ), then rank(x i ,y k )i ,y j ). Given a threshold σ, we can define a classifier h:x→2 based on f( ) y , for an instance x i ∈ x, if f k (x i )>σ, then y j ∈h(x i ),otherwise
[0069] Such as figure 1 As shown, it is a schematic flow chart of the image labeling method based on multi-label learning described in Embodiment 1 of the present invention, and the method may include the following steps:
[0070] S100: Extract all the labels of the instance, and calculate the label importance degree of each label corresponding to each instance in the multi-label ...
Embodiment 2
[0150] The present invention also provides an image tagging terminal device based on multi-label learning, including a memory, a processor, and a computer program stored in the memory and operable on the processor, and the processor executes the computer program The steps in the above method embodiment of Embodiment 1 of the present invention are realized at the same time.
