Applied Marketing Analytics (AMA)2023Video ads are increasingly popular in digital marketing, but advertisers are unsure about how much 8 they improve performance over static ads and which consumer response, such as unmuting or 9 watching through the end, matters most. Using data from the online retail site Amazon.com, we 10 apply causal inference methods to both a monthlong and yearlong time horizon and find support 11 for our hypotheses.

ACL Findings 2023, NeurIPS 2022 Workshop on SyntheticData4ML2023There has been increasing interest in synthesizing data to improve downstream text-to-SQL tasks. In this paper, we examined the existing synthesized datasets and discovered that state-of-the-art text-to-SQL algorithms did not further improve on popular benchmarks when trained with augmented synthetic data. We observed two shortcomings: illogical synthetic SQL queries from independent column sampling and

ACL 20232023Recent works show the effectiveness of cache-based neural coreference resolution models on long documents. These models incrementally process a long document from left to right and extract relations between mentions and entities in a cache, resulting in much lower memory and computation cost compared to computing all mentions in parallel. However, they do not handle cache misses when high-quality entities

ACL Findings 20232023Answering complex questions often requires reasoning over knowledge graphs (KGs). State-of-the-art methods often utilize entities in questions to retrieve local subgraphs, which are then fed into KG encoder, e.g. graph neural networks (GNNs), to model their local structures and integrated into language models for question answering. However, this paradigm constrains retrieved knowledge in local subgraphs

KDD 20232023Pre-trained language models (PLMs) such as BERT, RoBERTa, and DeBERTa have achieved state-of-the-art performance on various downstream tasks. The enormous sizes of PLMs hinder their deployment in resource-constrained scenarios, e.g., on edge and mobile devices. To address this issue, many model compression approaches have been proposed to reduce the number of model parameters. This paper focuses on compressing
