    The process of data analysis in machine learning involves several steps. An essential part is feature extraction, where important attributes or patterns are drawn from raw data for further analysis. Key elements include:

    • Normalization: Adjusting data to a common scale without distorting differences in values.
    • Dimensionality Reduction: Techniques such as Principal Component Analysis (PCA) help reduce data volume while retaining essential information.
    • Feature Selection: Choosing the most informative features to improve the model's performance.
    These steps ensure that the algorithms are efficient and accurate in detecting pathological indicators from datasets.

    For example, in analyzing radiological images to detect fractures, machine learning models extract features like bone thickness, texture, and edges, enhancing the ability to identify abnormalities.

    Applications in Clinical Practice

    Machine learning-powered pathology detection is reshaping clinical practice by offering a range of applications:
