Если вы ознакомились с процессом обучения для оператора FP-Growth в RapidMiner (перейдите по ссылке в тексте справки), вы можете найти подробный пример процесса.Данные уже очень похожи на ваш пример [1]
Получить такие структурированные данные в RapidMiner легко.Либо воспользуйтесь кнопкой «Импорт данных», либо загрузите и подготовьте свои данные с помощью вспомогательного инструмента «Turbo Prep».
[1] просто введите & xml в окно разработки процесса:
