Abstract |

内容記述 |
In recent years, convolutional neural networks (CNN) have found active application in the field of computer-aided diagnosis (CAD). Typically, general-purpose, high performance detectors are designed by conducting machine learning provided with comprehensive sets of case images having different kinds of variations. The reasoning behind this is that images not included in learning are not expected to be successfully detected. In fact, a comparison of CNN trained using only relatively typical cases and CNN trained using a comprehensive set of cases showed superior performance by the latter. Such is also expected to be the case in the commercial release of CAD. This is because the cases used in development may not encompass the cases at the medical facilities that will actually operate the system. In response to this situation, this paper proposes a self-evolving CAD system that incorporates a relearning function. It is not possible to upgrade the detectors of previous CAD systems following their commercial release. As a remedy, we propose a mechanism for upgrading the detector, accomplished by endowing the CAD system with a misrecognition correction function that uses interpretation report information (i.e., electronic medical records), and performing relearning after certain data is applied. This function provided improved performance compared to when relearning is not performed. Moreover, multiple relearning resulted in gradual improvements, demonstrating a process by which the system evolved into a CAD system matched to the involved medical facility. |
