Direct Large Language Model Alignment Through Self-Rewarding Contrastive Prompt Distillation

no code implementations19 Feb 2024 Aiwei Liu, Haoping Bai, Zhiyun Lu, Xiang Kong, Simon Wang, Jiulong Shan, Meng Cao, Lijie Wen

In this paper, we propose a method to evaluate the response preference by using the output probabilities of response pairs under contrastive prompt pairs, which could achieve better performance on LLaMA2-7B and LLaMA2-13B compared to RLAIF.

RGI: robust GAN-inversion for mask-free image inpainting and unsupervised pixel-wise anomaly detection

no code implementations24 Feb 2023 Shancong Mou, Xiaoyi Gu, Meng Cao, Haoping Bai, Ping Huang, Jiulong Shan, Jianjun Shi

In this paper, we propose a Robust GAN-inversion (RGI) method with a provable robustness guarantee to achieve image restoration under unknown \textit{gross} corruptions, where a small fraction of pixels are completely corrupted.

BatchQuant: Quantized-for-all Architecture Search with Robust Quantizer

no code implementations NeurIPS 2021 Haoping Bai, Meng Cao, Ping Huang, Jiulong Shan

While single-shot quantized neural architecture search enjoys flexibility in both model architecture and quantization policy, the combined search space comes with many challenges, including instability when training the weight-sharing supernet and difficulty in navigating the exponentially growing search space.
