Multi-Objective Ranking for Live-Streaming: Balancing Fresh and Delayed Signals with Segment-Aware Targeting

arXiv:2608. 04455v1 Announce Type: cross Abstract: One of the most challenging problems entertainment live-streaming services face in recommendation systems is that user behaviors are sparse and delayed, and interaction data exhibits bias for different user segments.

The Price of Isolation: Estimating the Ecosystem Cost of Symmetric Two-Sided A/B Testing

arXiv:2608. 04432v1 Announce Type: cross Abstract: On two-sided content platforms, symmetric two-sided isolation (assigning matched fractions of creators and viewers to isolated treatment and control submarkets) is widely used for creator-side and cold-start experiments because it removes cross-arm marketplace interference.

Incremental Recommendation via Causal Models

The paper proposes an incremental recommendation approach that uses a causal model built from existing holdback data to avoid delivering redundant recommendations. By applying a dual‑threshold targeting policy, the system only recommends content when the likelihood of a treated stream is high and the likelihood of an organic stream is low, thereby reducing recommendation impressions by 7% without hurting overall consumption. Joint training with holdback data also improves the calibration of the treated head, suggesting that causal models capture more generalisable representations than purely observational models.

From Leakage to Fidelity: Reliable Benchmarking for Temporal Cascade Prediction

The paper critiques current temporal cascade prediction benchmarks for relying on leakage-prone random splits, limited datasets, and unexamined protocol effects. It proposes a fidelity-aware benchmarking suite featuring the Full Temporal protocol, overlap-based leakage diagnostics, and analyses of performance inflation and temporal drift. Additionally, it introduces the Taoke e‑commerce dataset with rich features and purchase conversions, and presents CasTemp as a lightweight reference method for scalable evaluation.
