CIKM 20222022E-commerce marketplaces protect shopper experience and trust at scale by deploying deep learning models trained on human annotated moderation data, for the identification and removal of advert imagery that does not comply with moderation policies (a.k.a. defective images). However, human moderation labels can be hard to source for smaller advert programs that target specific device types with separate formats

ECCV 2022 Workshop on TiE2022The topics of confidence and trust in modern scene-text recognition (STR) models have been rarely investigated in spite of their prevalent use within critical user-facing applications. We analyze confidence estimation for STR models and find that they tend towards overconfidence thus leading to overestimation of trust in the predicted outcome by users. To overcome this phenomenon we propose a word-level

CIKM 20222022Cold start is a challenge in product search. Profuse literature addresses related problems such as bias and diversity in search, and cold start is a classic topic in recommender systems research. While search cold start might be seen conceptually as a particular case in such areas, we find that available solutions fail to specifically and practically solve the cold-start problem in product search. The problem

CIKM 20222022In this paper, we study how to capture explicit periodicity to boost the accuracy of deep models in univariate time series forecasting. Recent advanced deep learning models such as recurrent neural networks (RNNs) and transformers have reached new heights in terms of modeling sequential data, such as natural languages, due to their powerful expressiveness. However, real-world time series are often more

CIKM 20222022Interleaving is an online evaluation technique that has shown to be orders of magnitude more sensitive than traditional A/B tests. It presents users with a single merged result of the compared rankings and then attributes user actions back to the evaluated rankers. Different interleaving methods in the literature have their advantages and limitations with respect to unbiasedness, sensitivity, preservation
