ACM Transactions on Recommender Systems2022Modern recommender systems are often modelled under the sequential decision-making paradigm, where the system decides which recommendations to show in order to maximise some notion of either imminent or long-term reward. Such methods often require an explicit model of the reward a certain context-action pair will yield – for example, the probability of a click on a recommendation. This common machine learning

KDD 2022 Workshop on Deep Learning Practice and Theory for High-Dimensional Sparse and Imbalanced Data (DLP)2022In this paper, we introduce a targeted data enrichment framework to mitigate the problem of biased training data distribution. In real world applications, it is often observed that the training data distribution differs from the online live traffic data due to multiple reasons such as topic changes, seasonalities, the nature of users. Our targeted data augmentation techniques generate samples that are most

ICDM 2022 Workshop on Foundation Models for Vision and Language2022To solve video-and-language grounding tasks, the key is for the network to understand the connection between the two modalities. For a pair of video and language description, their semantic relation is reflected by their encodings’ similarity. A good multi-modality encoder should be able to well capture both inputs’ semantics and encode them in the shared feature space where embedding distance gets properly

SLT 20222022In the last several years, end-to-end (E2E) ASR models have mostly surpassed the performance of hybrid ASR models. E2E is particularly well suited to multilingual approaches because it doesn’t require language-specific phone alignments for training. Recent work has improved multilingual E2E modeling over naive data pooling on up to several dozen languages by using both language-specific and language-universal

IEEE International Conference on Knowledge Graph (ICKG 2022)2022The development of both the theory and the practice of neural network models has been significant in the last decade. Novel solutions including Dropout and Batch Normalization (BN) have been proposed and pervasively adopted to overcome issues like over-fitting and to improve the convergence of the models. Despite of their remarkable success, in this paper we show that Dropout and BN can make the model biased
