Assessing the Performance Gain on Retail Article Categorization at the Expense of Explainability and Resource Efficiency

Current state-of-the-art methods for text classification rely on large deep neural networks. For use cases such as product cataloging, their required computational resources and lack of explainability may be problematic: not every online shop can afford a vast IT infrastructure to guarantee low latency in their web applications and some of them require sensitive categories not to be confused. This motivates alternative methods that can perform close to the mentioned methods while being explainable and less resource-demanding. In this work, we evaluate an explainable framework consisting of a representation learning model for article descriptions and a similarity-based classifier. We contrast its results with those obtained by DistilBERT, a solid low-resource baseline for deep learning-based models, on two different retail article categorization datasets; and we finally discuss the suitability of the different presented …
