Abstract:

Machine learning algorithms are playing an increasingly important role in medical detection
and diagnosis, especially for breast tumor classification, detection and diagnosis. We
evaluate these machine learning methods based on criterions including accuracy,
sensitivity, specificity and efficiency. We then summarize the characteristics of different
classifiers according to the experimental results of different breast tumor databases: all
of the classifiers can achieve relatively ideal performance in terms of testing efficiency.
The linear discriminant analysis and the extreme learning machine have excellent
classification performance and high training efficiency while the support vector machine
has average classification performance and a long training time, and the artificial neural
network has relatively low sensitivity but an extremely high specificity.
 

Key words: breast tumor, machine learning, performance comparison
