Summary

Click-through rate (CTR) prediction is crucial in online advertising, and embedding techniques have improved CTR prediction accuracies. However, these techniques are data demanding and struggle with new ads that have little logging data, known as the cold-start problem. To address this, a meta-learning approach called Meta-Embedding is proposed, which learns to generate initial embeddings for new ad IDs. The method trains an embedding generator using previously learned ads and gradient-based meta-learning, allowing it to learn how to learn better embeddings. Experimental results on three real-world datasets show that Meta-Embedding significantly improves both cold-start and warm-up performances for six existing CTR prediction models.
