Интро¶
Компании электронной коммерции, такие как AMazon, ozon и др используют различные системы рекомендаций, чтобы предлагать клиентам предложения. Amazon в настоящее время использует совместную фильтрацию элемент-элемент, которая масштабируется до массивных наборов данных и создает высококачественную систему рекомендаций в режиме реального времени. Эта система является своего рода системой фильтрации информации, которая пытается предсказать «рейтинг» или предпочтения, которые интересуют пользователя.

Рекомендация по популярности¶
Система рекомендаций на основе популярности работает с трендом. В основном она использует предметы, которые сейчас в тренде. Например, если есть какой-либо продукт, который обычно покупает каждый новый пользователь, есть вероятность, что он может предложить этот элемент только что зарегистрировавшемуся пользователю.
Проблема с системой рекомендаций, основанной на популярности, заключается в том, что при этом методе персонализация недоступна, то есть, даже если вы знаете поведение пользователя, вы не можете рекомендовать элементы соответственно.
