KDD 2021 Workshop on Data-Efficient Machine Learning2021In a large-scale Spoken Language Understanding system, Natural Language Understanding (NLU) models are typically decoupled, i.e, trained and updated independently, from the upstream Automatic Speech Recognition (ASR) system that provides textual hypotheses for the user’s voice signal as input to NLU. Such ASR hypotheses often contain errors causing severe performance degradation as the downstream NLU models

CIKM 20212021Seasonality is an important dimension for relevance in e-commerce search. For example, a query jacket has a different set of relevant documents in winter than summer. For an optimal user experience, the e-commerce search engines should incorporate seasonality in product search. In this paper, we formally introduce the concept of seasonal relevance, define it and quantify using data from a major e-commerce

ArabWIC 20212021The recent rapid progress of deep learning algorithms in generating realistic images, especially in Generative Adversarial Networks (GAN) and Variational Auto-Encoders (VAE), has helped advance new applications. Examples of such applications range from generating and manipulating new synthetic data for self-driving cars, to building/urban architectures, to interior design, and gaming. Furthermore, several

ICCV 2021 Workshop and Challenge on Chalearn Face Anti-spoofing2021In this paper, we focus on improving the online face liveness detection system to enhance the security of the downstream face recognition system. Most of the existing framebased methods are suffering from the prediction inconsistency across time. To address the issue, a simple yet effective solution based on temporal consistency is proposed. Specifically, in the training stage, to integrate the temporal

ICCV 20212021We propose a new method to detect deepfake images using the cue of the source feature inconsistency within the forged images. It is based on the hypothesis that images’ distinct source features can be preserved and extracted after going through state-of-the-art deepfake generation processes. We introduce a novel representation learning approach, called pair-wise self-consistency learning (PCL),for training
