Speak & Improve Challenge 2025: Tasks and Baseline Systems

no code implementations16 Dec 2024 Mengjie Qian, Kate Knill, Stefano Banno, Siyuan Tang, Penny Karanasou, Mark J. F. Gales, Diane Nicholls

Linked with the challenge, the Speak & Improve (S&I) Corpus 2025 is being pre-released, a dataset of L2 learner English data with holistic scores and language error annotation, collected from open (spontaneous) speaking tests on the Speak & Improve learning platform.

LDACP: Long-Delayed Ad Conversions Prediction Model for Bidding Strategy

no code implementations25 Nov 2024 Peng Cui, Yiming Yang, Fusheng Jin, Siyuan Tang, Yunli Wang, Fukang Yang, Yalong Jia, Qingpeng Cai, Fei Pan, Changcheng Li, Peng Jiang

To alleviate the issue of discontinuity in one-hot hard labels, the Bucket Classification Module with label Smoothing method (BCMS) converts one-hot hard labels into non-normalized soft labels, then fits these soft labels by minimizing classification loss and regression loss.

Breast tumor classification based on self-supervised contrastive learning from ultrasound videos

no code implementations20 Aug 2024 Yunxin Tang, Siyuan Tang, Jian Zhang, Hao Chen

Further, we assessed the dependence of our pretrained model on the number of labeled data and revealed that <100 samples were required to achieve an AUC of 0. 901.

Learn and Don't Forget: Adding a New Language to ASR Foundation Models

no code implementations9 Jul 2024 Mengjie Qian, Siyuan Tang, Rao Ma, Kate M. Knill, Mark J. F. Gales

If only adaptation parameters are used, the language capabilities are maintained but at the cost of performance in the new language.

Cross-Lingual Transfer Learning for Speech Translation

no code implementations1 Jul 2024 Rao Ma, Mengjie Qian, Yassir Fathullah, Siyuan Tang, Mark Gales, Kate Knill

By fine-tuning the Whisper decoder with only English-to-Chinese speech translation data, improved performance for translation to Chinese can be obtained for multiple languages, in addition to English.

The Janus Interface: How Fine-Tuning in Large Language Models Amplifies the Privacy Risks

1 code implementation24 Oct 2023 Xiaoyi Chen, Siyuan Tang, Rui Zhu, Shijun Yan, Lei Jin, ZiHao Wang, Liya Su, Zhikun Zhang, XiaoFeng Wang, Haixu Tang

In our research, we propose a novel attack, Janus, which exploits the fine-tuning interface to recover forgotten PIIs from the pre-training data in LLMs.

Gradient Shaping: Enhancing Backdoor Attack Against Reverse Engineering

no code implementations29 Jan 2023 Rui Zhu, Di Tang, Siyuan Tang, Guanhong Tao, Shiqing Ma, XiaoFeng Wang, Haixu Tang

Finally, we perform both theoretical and experimental analysis, showing that the GRASP enhancement does not reduce the effectiveness of the stealthy attacks against the backdoor detection methods based on weight analysis, as well as other backdoor mitigation methods without using detection.

Selective Amnesia: On Efficient, High-Fidelity and Blind Suppression of Backdoor Effects in Trojaned Machine Learning Models

no code implementations9 Dec 2022 Rui Zhu, Di Tang, Siyuan Tang, XiaoFeng Wang, Haixu Tang

Our idea is to retrain a given DNN model on randomly labeled clean data, to induce a CF on the model, leading to a sudden forget on both primary and backdoor tasks; then we recover the primary task by retraining the randomized model on correctly labeled clean data.
