<p>The Department of Defense struggles to develop and maintain cutting-edge software through the Defense Acquisition System. The pace of improvements in machine learning algorithms and software suggests the organization will fail to rapidly develop systems incorporating the latest innovations to meet its intelligence-related media analysis needs. In contrast, the trend of industry and academia releasing algorithms and software under permissive licenses bestows defense organizations with an opportunity. These groups can potentially overcome resource shortfalls and long acquisition timelines by implementing machine learning solutions with open-source software.We test this hypothesis by employing an open-source software library to evaluate publicly available deep learning algorithms on three prior defense-related datasets. We then compare performance of deep convolutional neural networks to past methods for detecting AK-47s, ships, and screenshots in images. Applying proven algorithms through the software framework, we test three object detectors that exceed or match classification performance for all three experiments in a third of the development time available to designers of the previous algorithms. We relate these tests to defense scenarios in order to provide a logical argument and empirical measure of the utility of open-source machine learning frameworks to meet the Department of Defense's intelligence-related media analysis needs.
