  • 14-2eWhen new data have been collected, do you reevaluate the performance of the AI model?
    • After obtaining new data, a comparison of performance with the existing AI model is necessary to use the new data in the AI system. Even if the new data is judged by humans to be similar to the existing training data, the new data may differ from the data attributes the AI learned from the existing data. The following are examples that require reevaluation of the AI model performance after adding new data.
     Speech recognition AI model for remote elderly care service: The performance of the speech recognition AI model, which had been recognizing the speech of the previous elderly, is reevaluated to provide the same or better speech recognition service for the previous and new elderly, if additional data about the new elderly were incorporated due to changes in population distribution and the scope of defining elderly
     Face recognition AI model for tracking missing children: The result of training using new training datasets showed the same or improved performance in face recognition

    • It is necessary to conduct performance evaluation and analysis using the most representative AI algorithm of the domain for the new data. Refer to the following processes for performance evaluation due to obtaining new data.
     Acquire representative AI model and previous training model for performance evaluation and comparative analysis
     Choose appropriate performance evaluation indicators for the model and the sector of the AI
     Design tests for performance evaluation (e.g. choose a quantitative or qualitative testing method, set parameters of testing models, detailed planning of the test)
     Conduct tests and analyze results (e.g. determine the redesigning, expanding, and retraining of model if needed, or assess new data based on the results)
