Abstract—Breast Cancer is the most widespread cancer
amongst women in the world. An increase in the density of
breast may lead to an increase in the risk of breast cancer. For
the accurate diagnosis of breast cancer, these days Machine
learning-based computer-aided diagnosis systems are widely
used to assist the radiologists. However, there is still a scope of
improvement in the computer-aided diagnosis system for the
feature selection problem, which is considered as an
optimization problem. Optimization techniques are the
methods where the finest solution to a problem is found by
using random search mechanism. Grey wolf optimization is one
of the most recent optimization algorithms. This paper presents
an enhanced version of Grey Wolf Optimization algorithm and
tests the performance of the proposed version of the algorithm
on thirteen different benchmark functions and the binary
version of the proposed algorithm is used for selecting optimal
number of features for breast density classification problem.
Index Terms—Breast density classification, feature selection grey wolf optimization, opposition based learning.
