An Embedding-Based Grocery Search Model at Instacart. (arXiv:2209.05555v1 [cs.CL])

The key to e-commerce search is how to best utilize the large yet noisy log
data. In this paper, we present our embedding-based model for grocery search at
Instacart. The system learns query and product representations with a two-tower
transformer-based encoder architecture. To tackle the cold-start problem, we
focus on content-based features. To train the model efficiently on noisy data,
we propose a self-adversarial learning method and a cascade training method.
AccOn an offline human evaluation dataset, we achieve 10% …
