Detect Profane Language in Streaming Services to Protect Young Audiences

no code implementations ACL (ECNLP) 2021 Jingxiang Chen, Kai Wei, Xiang Hao

With the rapid growth of online video streaming, recent years have seen increasing concerns about profane language in their content.

Toward Equitable Access: Leveraging Crowdsourced Reviews to Investigate Public Perceptions of Health Resource Accessibility

no code implementations15 Feb 2025 Zhaoqian Xue, Guanhong Liu, Kai Wei, Chong Zhang, Qingcheng Zeng, Songhua Hu, Wenyue Hua, Lizhou Fan, Yongfeng Zhang, Lingyao Li

Our findings reveal that public perceptions of health resource accessibility varied significantly across the U. S., with disparities peaking during the pandemic and slightly easing post-crisis.

Towards Single-Lens Controllable Depth-of-Field Imaging via Depth-Aware Point Spread Functions

1 code implementation15 Sep 2024 Xiaolong Qian, Qi Jiang, Yao Gao, Shaohua Gao, Zhonghua Yi, Lei Sun, Kai Wei, Haifeng Li, Kailun Yang, Kaiwei Wang, Jian Bai

A Depth-aware Controllable DoF Imaging (DCDI) framework is proposed equipped with All-in-Focus (AiF) aberration correction and monocular depth estimation, where the recovered image and corresponding depth map are utilized to produce imaging results under diverse DoFs of any high-end lens via patch-wise convolution.

End-to-end spoken language understanding using joint CTC loss and self-supervised, pretrained acoustic encoders

no code implementations4 May 2023 Jixuan Wang, Martin Radfar, Kai Wei, Clement Chung

It is challenging to extract semantic meanings directly from audio signals in spoken language understanding (SLU), due to the lack of textual information.

Dialog act guided contextual adapter for personalized speech recognition

no code implementations31 Mar 2023 Feng-Ju Chang, Thejaswi Muniyappa, Kanthashree Mysore Sathyendra, Kai Wei, Grant P. Strimel, Ross McGowan

Specifically, it leverages dialog acts to select the most relevant user catalogs and creates queries based on both -- the audio as well as the semantic relationship between the carrier phrase and user catalogs to better guide the contextual biasing.

Multi-task RNN-T with Semantic Decoder for Streamable Spoken Language Understanding

no code implementations1 Apr 2022 Xuandi Fu, Feng-Ju Chang, Martin Radfar, Kai Wei, Jing Liu, Grant P. Strimel, Kanthashree Mysore Sathyendra

In addition, the NLU model in the two-stage system is not streamable, as it must wait for the audio segments to complete processing, which ultimately impacts the latency of the SLU system.

Mixed Robust/Average Submodular Partitioning: Fast Algorithms, Guarantees, and Applications

no code implementations NeurIPS 2015 Kai Wei, Rishabh K. Iyer, Shengjie Wang, Wenruo Bai, Jeff A. Bilmes

In the present paper, we bridge this gap, by proposing several new algorithms (including greedy, majorization-minimization, minorization-maximization, and relaxation algorithms) that not only scale to large datasets but that also achieve theoretical approximation guarantees comparable to the state-of-the-art.

Mixed Robust/Average Submodular Partitioning: Fast Algorithms, Guarantees, and Applications to Parallel Machine Learning and Multi-Label Image Segmentation

no code implementations NeurIPS 2015 Kai Wei, Rishabh Iyer, Shengjie Wang, Wenruo Bai, Jeff Bilmes

While the robust versions have been studied in the theory community, existing work has focused on tight approximation guarantees, and the resultant algorithms are not, in general, scalable to very large real-world applications.
