Study reveals methods to enhance daily item embedding compatibility for CTR prediction

A new study on arXiv explores methods to improve the compatibility of daily item embeddings, which are crucial for predicting user behavior like click-through rates (CTR). The research compares Word2Vec with an adaptation of XSimGCL, evaluating various techniques such as initialization, alignment, and scale management. Key findings indicate that interventions like ID-init and orthogonal alignment significantly boost embedding compatibility and CTR, while daily global rescaling effectively manages accumulated scale over time. The study also demonstrates that dimensionality-reducing encoders can further adapt embeddings to residual drift, suggesting a combination of upstream stabilization, scale management, and downstream task learning is beneficial for industrial applications.

    Cross-Day Compatibility of Daily Item Embeddings: An Empirical Study of Alignment, Scale Management, and CTR Adaptation

    Daily item co-occurrence embeddings are paired with next-day behavior without future-behavior leakage. Multi-day click-through rate (CTR) training therefore mixes versions whose directions and norms may differ for the same item. We compare Word2Vec and an item-graph XSimGCL adapt…
