Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of data processing, in particular to an image noise label feature selection method, system, storage medium and computer. BACKGROUND

[0002] With the rapid development of large-scale multimedia data and computer vision technology, automatic annotation of image data has become a key task in practical applications. Due to the dependence on crowd-sourced annotation, online scraping or weakly supervised information to generate labels, there are often problems such as omission, error or redundancy in the labels of image data, forming a significant noise label phenomenon. Especially in the task of bird image recognition and classification, due to the large number of bird species, high similarity in appearance and complex habitat, the bird image labels obtained through the crowd-sourcing platform often have noise problems such as species mislabeling, subspecies confusion and juvenile bird label errors. These noise labels can interfere with the training process of classification, retrieval and other models, and affect the accuracy of applications such as bird protection, ecological monitoring and intelligent bird watching. Therefore, how to extract accurate and effective label information from noisy bird image data is a technical problem that needs to be solved in the field of weakly supervised learning.

[0003] To reduce the negative impact of noise labels on bird image learning tasks, one of the key technical problems is to perform effective feature selection on noisy bird image data. By extracting high-dimensional features from the original bird image data and then selecting the most relevant discriminative features to the true semantics using a feature selection method, the performance of subsequent visual tasks such as classification, retrieval or target detection can be significantly improved. However, existing bird image feature selection methods often rely on a single correlation measure or assume that the labels are completely accurate, making it difficult to adapt to the feature-label dependence distortion and label confusion problems caused by label noise.

[0004] At the same time, image data itself usually has complex nonlinear distribution characteristics and multi-level local structure characteristics. Traditional feature selection methods often ignore the local consistency and structure information between samples, resulting in insufficient resistance of the selected features to noise labels, thereby affecting the generalization ability of the model. Therefore, how to combine multi-level granular structure evolution and fuzzy label representation, fully utilize the topological properties and local stability of image data, and perform robust feature selection on noisy bird image samples has become a core technical difficulty that needs to be broken through in the field of image noise label learning.

[0087] Embodiment one

[0088] Please refer to Figure 1 , which shows the image noise label feature selection method in the first embodiment of the present application, which specifically includes steps S1 to S6:

[0089] S1: obtaining the image noise label data set to be processed, wherein the image noise label data set contains both feature space and label space;

[0090] In specific implementation, the frame diagram of the bird image noise label feature selection method provided in the present embodiment is as shown in Figure 2 The pre-trained ResNet network is used to extract deep features of the bird image, and the image data is converted into a structured multi-dimensional feature vector, forming a data set that covers both image feature space and candidate label space;

[0091] Specifically, let Examples of a sample set in a feature space, let denote a label space containing possible labels. For a given noisy-labeled bird image dataset where is the embedding vector of the th sample in the feature space, is the candidate label set associated with the sample. The candidate label set can be mixed with true labels and noise labels, typically characterized by label uncertainty. For any candidate label , if , it indicates that the label is a candidate label for the sample ; if , it indicates that the label is irrelevant to the sample .

[0092] S2: Embed the sample set in the image noisy-labeled dataset into multi-granularity fuzzy cluster groups using an adaptive multi-kernel fusion and dynamic parameter optimization mechanism to construct a dynamic fuzzy membership evaluation matrix and determine the multi-dimensional fuzzy mapping relationship between the quantized sample-cluster and sample-class;

[0093] In specific implementation, this step faces the distribution characteristics of bird image features (such as feather texture details, feather color texture details, beak contour, background environment, etc.), and uses an adaptive multi-kernel fusion and dynamic parameter optimization mechanism to perform prior subspace division on the sample set, thereby constructing multiple original semantic cluster centers. This mechanism can automatically adjust the kernel function parameters according to the nonlinear distribution of bird images in the feature space, effectively capturing feature differences caused by changes in lighting, differences in posture, occlusion, and background diversity. Subsequently, through the fusion of fuzzy set theory, a soft attachment relationship between samples and cluster centers is realized, so that the gradual aggregation of true species semantics can still be maintained in the presence of label noise. The step S2 specifically includes:

[0094] Step S21: In the multi-kernel framework, a dynamic weight is given to each kernel function, and an entropy regularization term is introduced into the objective function to constrain the weight distribution:

[0095] ;

[0096] wherein, denotes the overall objective function of multi-kernel fuzzy clustering, which is used to simultaneously optimize the clustering quality and the rationality of kernel weight distribution, wherein, denotes the membership matrix, denotes the cluster center matrix, denotes the kernel weight distribution vector; denotes the preset number of clustering clusters; denotes the total number of samples in the data set; denotes the total number of kernel functions in the multi-kernel framework; in the fuzzy clustering process, denotes the original sample (bird image sample) the fuzzy membership of the first cluster, the value is between 0 and 1, and satisfies the normalization constraint condition , is a fuzzy index, usually greater than 1, used to control the fuzziness of the cluster boundary;

[0097] In the multi-kernel mapping mechanism, denotes the dynamic weight coefficient of the first kernel function, and the weight satisfies and constraint condition; denotes the feature vector obtained after the first kernel function maps the original sample (bird image sample) to a high-dimensional feature space; denotes the cluster center of the first cluster in the feature space induced by the first kernel function; the distance term calculates the Euclidean distance square of the sample in the specific kernel space and the corresponding cluster center, which is used to measure the similarity between the sample and the cluster center;

[0098] In the bird image with noisy labels, different kernel functions are designed to capture different types of visual features: color kernel extracts feather color distribution, eye circle color, etc. Features are used to distinguish species with significant color differences; texture kernel captures feather texture, wing spot details, etc. Information should be used to deal with the situation where the feather color is similar but the texture is obviously different; shape kernel analyzes the beak shape geometry, body contour and wing shape, etc. Used to distinguish species with large differences in body characteristics; multi-scale kernel captures detailed features under different shooting distances, poses and scales.

[0099] The second part of the objective function introduces an entropy regularization mechanism, where is a regularization parameter used to control the uniformity of the kernel weight distribution; the entropy term as a constraint term, the greater the negative value of this term when the kernel weight distribution is more uniform, thereby preventing the algorithm from degenerating into a single kernel function, ensuring the effectiveness of multi-kernel fusion. The whole objective function realizes the optimization of sample clustering in multi-kernel space and the adaptive adjustment of kernel weight by minimizing the weighted clustering error and maximizing the entropy constraint term;

[0100] Step S22: By dynamically adjusting the degree of membership of each cluster to the sample, the rationality of fuzzy division is ensured:

[0101] ;

[0102] wherein, denotes the cluster center of the i-th cluster in the feature space induced by the j-th kernel function;

[0103] Step S23: The kernel weight update formula dynamically allocates the importance of different kernel functions through the entropy regularization term. The allocation of the weight is based on the contribution of the current kernel function in the cluster, and the regularization parameter controls the uniformity of the weight distribution:

[0104] ;

[0105] wherein, denotes the cluster center of the i-th cluster in the feature space induced by the j-th kernel function;

[0106] Step S24: In the kernel space, the cluster center cannot be explicitly expressed and needs to be implicitly calculated through the kernel matrix. The membership degree weighted kernel mapping data mean is used to update the cluster center, ensuring the feasibility of the algorithm in the feature space:

[0107] ;

[0108] This process can make the cluster centers of bird images in multiple feature modalities closer to the visual feature distribution of real species;

[0109] Step S25: After updating, the new membership matrix and the deviation between the previous membership matrix and the new center and the previous center are calculated in turn. If the deviation is less than the preset threshold , the algorithm terminates; otherwise, return to step S21 and repeat execution until the stop condition is met:

[0110] or ;

[0111] wherein, and denote the set of all cluster centers generated in the i-th iteration, and denote the set of all cluster centers generated in the i-th iteration, ​​​​​​The preset convergence threshold is set according to the complexity of the bird image feature distribution (such as species diversity and background interference intensity).

[0112] S3: Based on the global spectrum feature mapping mechanism, a macro coarse-grained granule skeleton is constructed, the granules with insufficient marking isomorphism or structural entropy exceeding the threshold are fused into a quality measurement model for joint evaluation, and a multi-level high-precision sub-granule cluster is dynamically evolved through a progressive self-organizing fission algorithm.

[0113] In specific implementation, this step is based on the distribution characteristics of bird image features in high-dimensional space (for example, the appearance difference of the same species under different postures, light, and habitat environment) to quickly generate an initial macro granule based on full data spectrum information, and a double-mode evaluation mechanism is embedded for real-time screening of granules containing high-noise labels or mixed species. Through a progressive self-organizing fission algorithm, complex granules are gradually decomposed into high-purity sub-granules that can distinguish fine-grained species characteristics, thereby improving the ability to distinguish subspecies differences and gender differences. The specific steps include:

[0114] Step S31: The data set is divided into two initial granules and by performing a binary clustering algorithm on the data set Step S32: The radius of each granule is calculated according to the following formula: wherein, the calculation formula of the center of each granule is as follows:

[0115] ;

[0116] wherein, n is the number of samples in the granule, and

[0117] Step S32: The radius of each granule is calculated according to the following formula:

[0118] ;

[0119] Step S33: Check whether the above granules meet the threshold value requirement:

[0120] ;

[0121] wherein, n is the number of samples in the granule, and ​​​​​​​​​​The purity value is a set of markers. The formula measures the concentration of the marker distribution by calculating the maximum frequency of each marker in the sample within the sphere. The higher the purity value, the more consistent the marker distribution of the samples within the sphere. For example, when most images in the same sphere are labeled as "light-vented bulbul" and have consistent feather features, the purity is high. Indicates granules The information entropy is used to measure the uncertainty of the markings inside the granule, where... Indicates a marker In granules The probability of occurrence within a granule is calculated using this formula, which measures the degree of uncertainty in the distribution of markers within the granule. For example, when different species with similar plumage (Grey-headed Bulbul and White-headed Bulbul) are mixed in the same granule, the entropy value is higher. A higher entropy value indicates a more complex and chaotic distribution of markers within the granule. The parameter adjusts the weight ratio of purity and entropy, when When the value is lower than the preset threshold, it indicates that the labeling consistency of the granule is insufficient or the topology is too complex, and further splitting is required to improve the quality of the granule.

[0122] If the purity of a particle is lower than a preset threshold, binary clustering is performed to split it into two more consistent sub-particles. This process is recursively repeated until the purity of all particles meets the threshold, thus completing particle construction. This process is iterated until the purity of all particles meets the threshold requirement, at which point the splitting process terminates, completing adaptive particle construction.

[0123] S4: Within each fine sphere, weight-driven sphere calculation and fuzzy inference are integrated. Weights are automatically assigned based on the sample-sphere center distance, and a category-cluster coupling association matrix is ​​constructed. Through fuzzy synthesis operation, the cluster membership is optimized into category membership, and finally a highly recognizable label distribution is obtained.

[0124] In specific implementation, within each level of the granular sphere, based on the granular sphere geometric posture of bird image features, a multi-source weight-triggered distance metric strategy (such as color difference, texture difference, and shape difference) is fused to construct a cluster-class tensor mapping framework. This achieves adaptive mapping and fusion of sample-cluster membership to sample-class membership, thereby optimizing label disambiguation in species identification. Step S4 specifically includes:

[0125] Step S41: Based on the core idea of ​​multi-source weight triggering, and combined with the ideas of manifold learning and adaptive feature weighting, a hybrid distance metric algorithm that integrates local geometric structure and dynamic feature importance is constructed to obtain the weight information of samples. By introducing a third-order nonlinear control mechanism, the scene adaptability of the distance metric is significantly improved.

[0128] Step S42: On the basis of having obtained the fuzzy membership matrix and the sample weight , a category-cluster association matrix is constructed:

[0129] ;

[0130] wherein the initial value of the matrix A is a zero matrix, and the dimension is , is the number of categories, is the number of clusters, and the element in the matrix represents the association strength of the th category and the th cluster. By using the fuzzy logic reasoning method, the association matrix is subjected to fuzzy composition operation with the sample membership of each cluster, so as to realize the conversion of the sample membership of the cluster to the membership of the category, thereby reducing the marking confusion between the species with similar colors. S5: A rough perception feature evaluation framework based on granule topology driving is constructed, the adaptive neighborhood is defined according to the granule geometric characteristics, the local neighborhood which is cohesive and non-overlapping is dynamically divided, the decision equivalent class is extracted by combining the rough set upper and lower approximation and the extended positive region model, the contribution degree of each feature to the decision system is determined by fusing the multi-granule decision boundary information based on the dependence quantification model;

[0132] In specific implementation, a coarse perception feature evaluation framework based on particle topology was constructed. Relying on the geometric topological information of the particles, an adaptive neighborhood for each sample was dynamically defined, achieving multi-dimensional partitioning of the label distribution space. Using extended upper and lower approximate boundaries and a positive domain extension model, a refined characterization of decision equivalence classes was completed. Based on a dynamic dependency measurement model, the dependency of each feature in different decision classes was calculated in real time, thereby accurately identifying and ranking discriminative features. Step S5 specifically includes:

[0133] Step S51: Let the complete sample set be The complete set of features is Select a subset of attributes as .right The particle sphere calculation is applied to obtain the set of particles in the characteristic space. For any sample Define it in the feature subset The adaptive neighborhood is as follows:

[0134] ;

[0135] in, and It is a pellet. The center and radius, For feature subset The distance below, defined by the center and radius of the sphere, dynamically divides the sample into “cohesive” and “non-overlapping” local neighborhoods, avoiding the rigidity of fixed radius neighborhoods and ensuring that samples within the neighborhood maintain a high degree of consistency in species characteristics;

[0136] Step S52: Construct a dynamic labeled spheroid group set, and use an adaptive spheroid splitting algorithm to split the real labeled global domain. Multi-scale nonlinear spatial reconstruction is performed to form an optimal granular topological partition with optimal coverage of the entire domain:

[0137] ;

[0138] Each This represents a single marked sphere that collectively covers the entire marked space, with each sphere achieving optimal purity and coverage.

[0139] Step S53: In the given decision system In the middle, decision attributes Divide the samples into equivalence classes, using feature subsets The generated set of spheres Define upper and lower approximate sets:

[0140] , ;

[0141] wherein, , by granular ball and the non-empty intersection relation of equivalence class , determine the coverage boundary of the decision class;

[0142] ;

[0143] by granular ball and the total inclusion relation of equivalence class , extract the core support domain of the decision class. In the bird application, the upper approximation set usually contains typical samples with completely consistent feather color, texture and morphological characteristics, such as high-definition photos of adult male birds; the lower approximation set contains boundary samples that are easy to be confused with other species, such as juvenile birds, intermediate individuals with feather color, or photos with partial occlusion;

[0144] Step S54: Because the label space of the multi-label data set itself has inherent ambiguity, it is difficult to clearly segment the decision boundary, and the lower approximation set alone cannot fully reflect the contribution of boundary samples to the decision. Therefore, samples outside the lower approximation set but still have "weak association" or "partial overlap" with a certain decision class are also included in the measurement of the positive domain, so as to more comprehensively characterize the multi-label decision boundary. An extended positive region dependence quantification model for image noise label decision system is constructed:

[0145] ;

[0146] wherein, is the sample that belongs to and , and represents the sample set in but not in , is the distance from the sample to the center of the granular ball, is the distance from the sample to the center of the granular ball;

[0147] Step S55: Through the dynamic multi-granularity collaborative feature importance quantification algorithm, the rough set theory and the granular ball calculation framework are fused to realize the accurate evaluation of the features:

[0148] .

[0149] Specifically, the multi-granularity decision boundary information is fused to output a ranking of the contribution of each feature to the classification of birds. In actual deployment, the ranking result can be used to prioritize the features with the highest contribution to species discrimination and the least sensitivity to environmental changes for model training and updating of an automatic bird recognition system in the wild. S6: A particle ball structure consistency verification mechanism is introduced to measure the expression stability of the features in the local domain of the particle ball from the perspective of structure preservation, and the importance of the features is evaluated at multiple levels through dependency and consistency.

[0150] In specific implementation, the conditional attribute subset from the training sample set The generated particle ball set A similarity quantification method based on the consistency of the internal sample structure of the particle ball is introduced to measure the similarity of the particle ball samples, specifically as follows:

[0151] Step S61: A similarity quantification algorithm based on the consistency of the internal sample structure of the particle ball is used to measure the similarity of the particle ball samples:

[0152] ;

[0153] wherein, indicates the cardinality of the particle ball set, The greater the value, the more consistent the feature distribution of the particle ball is, the higher the similarity between them is, and the clearer the boundary between different particle balls is, proving that the current feature subset has strong discrimination ability and expression effectiveness;

[0154] Step S62: Based on the additional feature importance evaluation mechanism, the discrimination contribution of the features is quantified by measuring the degree of change in the particle ball structure before and after the features are removed:

[0155] ;

[0156] Step S63: By constructing a feature dependency matrix and a particle ball internal sample consistency matrix, a multi-source dual-modal dependency-consistency joint evaluation method is used to evaluate the feature weight, realizing the fine quantification and ranking of the key features in high-dimensional data:

[0157] .

[0158] In summary, the image noise label feature selection method in the above embodiments of the present application adopts a sample soft partition mechanism driven by fuzzy membership, initializes fuzzy clusters, and on this basis introduces a quality-driven granular ball evolution strategy to construct a multi-granularity granular ball system from coarse to fine, and realizes dynamic disambiguation and noise interference suppression of the label space through progressive self-organizing fission; fusion of granular ball geometric topology and rough set approximation theory, define adaptive neighborhood range, use upper and lower approximation set and extended positive domain model to depict the boundary of decision equivalence class, and based on the dependence measurement model of multi-granular ball boundary fusion, realize high-precision quantitative evaluation of feature importance; construct a granular ball structure stability verification mechanism, evaluate the expression consistency and generalization ability of the selected features at different granularity levels from the two dimensions of sample similarity and feature disturbance response in the granular ball, and improve the robustness and reliability of feature selection; design a hierarchical weight integration strategy to weight and fuse the feature ranking results at multiple granularities, and finally obtain an optimal feature subset with strong noise resistance and high discrimination ability, providing stable and efficient input support for subsequent image noise label learning model.
