Recommendation Systems Shift Toward Semantic Planning
_reachsumit · x · 2026-07-13
Huawei shared technical insights on the evolution of representation learning and planning in recommendation systems: how systems are shifting from raw IDs to semantic IDs, and why "semantic planning" is necessary.
The core idea is to have the system predict the intended goal of an impression before it actually occurs, and then decide how to leverage massive amounts of information accordingly. This represents a design paradigm shift from "relying solely on IDs" to "performing semantic-layer planning first."
