Robust Diffusion Models for Adversarial Purification

no code implementations24 Mar 2024 Guang Lin, Zerui Tao, Jianhai Zhang, Toshihisa Tanaka, Qibin Zhao

We propose a novel robust reverse process with adversarial guidance, which is independent of given pre-trained DMs and avoids retraining or fine-tuning the DMs.

Efficient Nonparametric Tensor Decomposition for Binary and Count Data

1 code implementation15 Jan 2024 Zerui Tao, Toshihisa Tanaka, Qibin Zhao

Finally, to address the computational issue of GPs, we enhance the model by incorporating sparse orthogonal variational inference of inducing points, which offers a more effective covariance approximation within GPs and stochastic natural gradient updates for nonparametric models.

EpilepsyLLM: Domain-Specific Large Language Model Fine-tuned with Epilepsy Medical Knowledge

no code implementations11 Jan 2024 Xuyang Zhao, Qibin Zhao, Toshihisa Tanaka

Based on those powerful LLMs, the model fine-tuned with domain-specific datasets posseses more specialized knowledge and thus is more practical like medical LLMs.

YuruGAN: Yuru-Chara Mascot Generator Using Generative Adversarial Networks With Clustering Small Dataset

no code implementations17 Apr 2020 Yuki Hagiwara, Toshihisa Tanaka

However, it is difficult to apply class conditional GANs when the amount of original data is small and when a clear class is not given, such as a yuruchara image.

Generalized Gaussian Kernel Adaptive Filtering

no code implementations25 Apr 2018 Tomoya Wada, Kosuke Fukumori, Toshihisa Tanaka, Simone Fiori

The present paper proposes generalized Gaussian kernel adaptive filtering, where the kernel parameters are adaptive and data-driven.
