CIKM 20232023Predicting the click-through rate (CTR) of an item is a fundamental task in online advertising and recommender systems. CTR prediction models are typically trained on user click data from traffic logs. However, users are more likely to interact with items that were shown prominently on a website. CTR models often overestimate the value of such items and show them more often, at the expense of items of higher

SPIE 2023 Applications of Digital Image Processing XLVI2023Super-resolution video coding describes the process of coding video at lower resolution and upsampling the result. This process is included in the AV1 standard, which ensures the same super-resolution process is employed on all receiving devices. Regrettably, the design is limited to horizontal scaling with a maximum scale factor of two. In this paper, we analyze the benefit of enabling two-dimensional

CIKM 20232023Identifying similar products in e-commerce is useful in discovering relationships between products, making recommendations, and in-creasing diversity in search results. Product representation learning is the first step to define a generalized product similarity metric for search. The second step is to extend similarity search to a large scale (e.g., e-commerce catalog scale) without sacrificing quality.

CIKM 2023 Industry Day2023In industrial settings, it is often necessary to achieve language-level accuracy targets. For example, Amazon business teams need to build multilingual product classifiers that operate accurately in all European languages. It is unacceptable for the accuracy of product classification to meet the target in one language (e.g, English), while falling below the target in other languages (e.g, Portuguese). To

CIKM 20232023Traditionally, catalog relationship problems in e-commerce stores have been handled as pairwise classification tasks, which limit the ability of machine learning models to learn from the diverse relationships among different entities in the catalog. In this paper, we leverage heterogeneous graphs and Graph Neural Networks (GNNs) for improving catalog relationship inference. We start from investigating how
