Explicit Feedback
Preference signals that users actively express in recommendation systems, such as likes, saves and added topics. The intent is clear, but acquisition costs are high and the volume of data is small.
Timeline (last 90 days)
Recommender systems usually rely on two types of user signals: implicit feedback (such as dwell time and swipe speed) and explicit feedback (such as likes, saves and directly adding topics).
The advantage of explicit feedback is clear intent and low noise, while the disadvantage is high acquisition cost and a data volume far smaller than implicit behavior; implicit feedback signals are noisy and prone to misjudgment.
