    Summary

    A new hybrid Ant-Cuckoo Colony Optimization method improves breast cancer detection from digital mammograms. This technique efficiently selects crucial features, enhancing classification accuracy for early diagnosis.

    Area of Science:

    • Medical Imaging
    • Artificial Intelligence
    • Computational Biology

    Background:

    • Digital mammography is vital for breast cancer screening.
    • Gray Level Co-occurrence Matrix (GLCM) extracts textural features, but not all are essential for accurate detection.
    • Effective feature selection is crucial for improving classifier performance.

    Purpose of the Study:

    • To propose a novel hybrid metaheuristic algorithm, Ant-Cuckoo Colony Optimization (ACCO), for feature selection in digital mammograms.
    • To enhance the accuracy and efficiency of breast cancer detection through optimized feature selection.
    • To address the limitations of traditional Ant Colony Optimization (ACO) by integrating Cuckoo Search (CS) for improved local search capabilities.

    Main Methods:

    • Extraction of Gray Level Co-occurrence Matrix (GLCM) textural features from digital mammograms.

  • Development and application of the hybrid Ant-Cuckoo Colony Optimization (ACCO) algorithm for feature selection.
  • Classification of mammograms using Support Vector Machine (SVM) with Radial Basis Kernel Function (RBF).

    • Main Results:

    • The proposed hybrid Ant-Cuckoo Colony Optimization (ACCO) algorithm demonstrated superior accuracy in feature selection compared to standard ACO and Particle Swarm Optimization (PSO).
    • The ACCO algorithm effectively identified relevant features, leading to improved classification rates for distinguishing normal from abnormal mammograms.
    • Integration of Cuckoo Search (CS) into ACO enhanced the local search efficiency, overcoming the slow convergence issues of traditional ACO.

    Conclusions:

    • The hybrid Ant-Cuckoo Colony Optimization (ACCO) algorithm represents a significant advancement in feature selection for digital mammogram analysis.
    • This method offers a more accurate and efficient approach to breast cancer detection, potentially improving early diagnosis rates.
    • The study highlights the potential of hybrid metaheuristic approaches in medical image analysis and classification tasks.
