Adversarial Speech Generation and Natural Speech Recovery for Speech Content Protection

no code implementations LREC 2022 Sheng Li, Jiyi Li, Qianying Liu, Zhuo Gong

Moreover, based on the speech collection, we proposed a neural network-based frame-by-frame mapping method to recover the speech content by converting from the adversarial speech to the human speech.

Multi-task Peer-Review Score Prediction

no code implementations EMNLP (sdp) 2020 Jiyi Li, Ayaka Sato, Kazuya Shimura, Fumiyo Fukumoto

To handle the small size of published datasets on the target aspect of scores, we propose a multi-task approach to leverage additional information from other aspects of scores for improving the performance of the target.

CaDRec: Contextualized and Debiased Recommender Model

1 code implementation10 Apr 2024 Xinfeng Wang, Fumiyo Fukumoto, Jin Cui, Yoshimi Suzuki, Jiyi Li, Dongjin Yu

To tackle the skewed distribution, we propose two strategies for disentangling interactions: (1) modeling individual biases to learn unbiased item embeddings, and (2) incorporating item popularity with positional encoding.

Enhanced Coherence-Aware Network with Hierarchical Disentanglement for Aspect-Category Sentiment Analysis

no code implementations15 Mar 2024 Jin Cui, Fumiyo Fukumoto, Xinfeng Wang, Yoshimi Suzuki, Jiyi Li, Noriko Tomuro, Wanzeng Kong

To address the issue of multiple aspect categories and sentiment entanglement, we propose a hierarchical disentanglement module to extract distinct categories and sentiment features.

A Comparative Study on Annotation Quality of Crowdsourcing and LLM via Label Aggregation

no code implementations18 Jan 2024 Jiyi Li

Whether Large Language Models (LLMs) can outperform crowdsourcing on the data annotation task is attracting interest recently.

GhostVec: A New Threat to Speaker Privacy of End-to-End Speech Recognition System

no code implementations17 Nov 2023 Xiaojiao Chen, Sheng Li, Jiyi Li, Hao Huang, Yang Cao, Liang He

This paper demonstrates that an attacker can extract speaker information by querying speaker-adapted speech recognition (ASR) systems.

Reprogramming Self-supervised Learning-based Speech Representations for Speaker Anonymization

no code implementations17 Nov 2023 Xiaojiao Chen, Sheng Li, Jiyi Li, Hao Huang, Yang Cao, Liang He

Current speaker anonymization methods, especially with self-supervised learning (SSL) models, require massive computational resources when hiding speaker identity.

Abstract, Rationale, Stance: A Joint Model for Scientific Claim Verification

1 code implementation EMNLP 2021 Zhiwei Zhang, Jiyi Li, Fumiyo Fukumoto, Yanming Ye

In addition, we enhance the information exchanges and constraints among tasks by proposing a regularization term between the sentence attention scores of abstract retrieval and the estimated outputs of rational selection.

Learning from Multiple Annotators by Incorporating Instance Features

no code implementations29 Jun 2021 Jingzheng Li, Hailong Sun, Jiyi Li, Zhijun Chen, Renshuai Tao, Yufei Ge

Learning from multiple annotators aims to induce a high-quality classifier from training instances, where each of them is associated with a set of possibly noisy labels provided by multiple annotators under the influence of their varying abilities and own biases.

A Neural Local Coherence Analysis Model for Clarity Text Scoring

no code implementations COLING 2020 Panitan Muangkammuen, Sheng Xu, Fumiyo Fukumoto, Kanda Runapongsa Saikaew, Jiyi Li

Local coherence relation between two phrases/sentences such as cause-effect and contrast gives a strong influence of whether a text is well-structured or not.

CrowDEA: Multi-view Idea Prioritization with Crowds

no code implementations1 Aug 2020 Yukino Baba, Jiyi Li, Hisashi Kashima

We propose an approach, called CrowDEA, which estimates the embeddings of the ideas in the multiple-criteria preference space, the best viewpoint for each idea, and preference criterion for each evaluator, to obtain a set of frontier ideas.

A Dataset of Crowdsourced Word Sequences: Collections and Answer Aggregation for Ground Truth Creation

no code implementations WS 2019 Jiyi Li, Fumiyo Fukumoto

To ensure the quality of the crowdsourced data, people can assign multiple workers to one question and then aggregate the multiple answers with diverse quality into a golden one.
