Rewards with Negative Examples for Reinforced Topic-Focused Abstractive Summarization

no code implementations EMNLP (newsum) 2021 Khalil Mrini, Can Liu, Markus Dreyer

We introduce a deep reinforcement learning approach to topic-focused abstractive summarization, trained on rewards with a novel negative example baseline.

RAF-GI: Towards Robust, Accurate and Fast-Convergent Gradient Inversion Attack in Federated Learning

1 code implementation13 Mar 2024 Can Liu, Jin Wang, Dongyang Yu

Yet, FL users are susceptible to the gradient inversion (GI) attack which can reconstruct ground-truth training data such as images based on model gradients.

1D-Touch: NLP-Assisted Coarse Text Selection via a Semi-Direct Gesture

no code implementations26 Oct 2023 Peiling Jiang, Li Feng, Fuling Sun, Parakrant Sarkar, Haijun Xia, Can Liu

We introduce 1D-Touch, a novel text selection method that complements the carets-based sub-word selection by facilitating the selection of semantic units of words and above.

ONNXExplainer: an ONNX Based Generic Framework to Explain Neural Networks Using Shapley Values

no code implementations29 Sep 2023 Yong Zhao, Runxin He, Nicholas Kersting, Can Liu, Shubham Agrawal, Chiranjeet Chetia, Yu Gu

SHAP package is a leading implementation of Shapley values to explain neural networks implemented in TensorFlow or PyTorch but lacks cross-platform support, one-shot deployment and is highly inefficient.

On Conditional and Compositional Language Model Differentiable Prompting

no code implementations4 Jul 2023 Jonathan Pilault, Can Liu, Mohit Bansal, Markus Dreyer

Prompts have been shown to be an effective method to adapt a frozen Pretrained Language Model (PLM) to perform well on downstream tasks.

MedAug: Contrastive learning leveraging patient metadata improves representations for chest X-ray interpretation

no code implementations21 Feb 2021 Yen Nhi Truong Vu, Richard Wang, Niranjan Balachandar, Can Liu, Andrew Y. Ng, Pranav Rajpurkar

Our controlled experiments show that the keys to improving downstream performance on disease classification are (1) using patient metadata to appropriately create positive pairs from different images with the same underlying pathologies, and (2) maximizing the number of different images used in query pairing.

Quantifying the Security of Recognition Passwords: Gestures and Signatures

no code implementations21 Dec 2018 Can Liu, Shridatt Sugrim, Gradeigh D. Clark, Janne Lindqvist

We use a partial guessing metric, which demonstrates how many guesses an attacker needs to crack a percentage of the entire space, to compare the security of the distributions for gestures, signatures, and Android unlock patterns.
