Compress Polyphone Pronunciation Prediction Model with Shared Labels

no code implementations CCL 2020 Pengfei Chen, Lina Wang, Hui Di, Kazushige Ouchi, Lvhong Wang

In contrast to existing quantization with low precision data format and projection layer, we propose a novel method based on shared labels, which focuses on compressing the fully-connected layer before Softmax for models with a huge number of labels in TTS polyphone selection.

Let Real Images be as a Judger, Spotting Fake Images Synthesized with Generative Models

no code implementations25 Mar 2024 Ziyou Liang, Run Wang, Weifeng Liu, Yuyang Zhang, Wenyuan Yang, Lina Wang, Xingkai Wang

Unfortunately, the artifact patterns in fake images synthesized by different generative models are inconsistent, leading to the failure of previous research that relied on spotting subtle differences between real and fake.

Analyzing Adversarial Robustness of Deep Neural Networks in Pixel Space: a Semantic Perspective

no code implementations18 Jun 2021 Lina Wang, Xingshu Chen, Yulong Wang, Yawei Yue, Yi Zhu, Xuemei Zeng, Wei Wang

Previous works study the adversarial robustness of image classifiers on image level and use all the pixel information in an image indiscriminately, lacking of exploration of regions with different semantic meanings in the pixel space of an image.

Using contrastive learning to improve the performance of steganalysis schemes

no code implementations1 Mar 2021 Yanzhen Ren, YiWen Liu, Lina Wang

To decrease the computing complexity of the contrastive loss in supervised learning, we design a novel Steganalysis Contrastive Loss (StegCL) based on the equivalence and transitivity of similarity.

Combination of window-sliding and prediction range method based on LSTM model for predicting cryptocurrency

no code implementations9 Feb 2021 Yifan Yao, Lina Wang

The present study aims to establish the model of the cryptocurrency price trend based on financial theory using the LSTM model with multiple combinations between the window length and the predicting horizons, the random walk model is also applied with different parameter settings.

Towards a Robust Deep Neural Network in Texts: A Survey

no code implementations12 Feb 2019 Wenqi Wang, Run Wang, Lina Wang, Zhibo Wang, Aoshuang Ye

Recently, studies have revealed adversarial examples in the text domain, which could effectively evade various DNN-based text analyzers and further bring the threats of the proliferation of disinformation.
