SA-GS: Scale-Adaptive Gaussian Splatting for Training-Free Anti-Aliasing

1 code implementation28 Mar 2024 Xiaowei Song, Jv Zheng, Shiran Yuan, Huan-ang Gao, Jingwei Zhao, Xiang He, Weihao Gu, Hao Zhao

This integration is actually a limiting case of super-sampling, which significantly improves anti-aliasing performance over vanilla Gaussian Splatting.

AccoMontage-3: Full-Band Accompaniment Arrangement via Sequential Style Transfer and Multi-Track Function Prior

1 code implementation25 Oct 2023 Jingwei Zhao, Gus Xia, Ye Wang

The first component is a piano arranger that generates piano accompaniment for the lead sheet by transferring texture styles to the chords using latent chord-texture disentanglement and heuristic retrieval of texture donors.

Polyffusion: A Diffusion Model for Polyphonic Score Generation with Internal and External Controls

1 code implementation19 Jul 2023 Lejun Min, Junyan Jiang, Gus Xia, Jingwei Zhao

We propose Polyffusion, a diffusion model that generates polyphonic music scores by regarding music as image-like piano roll representations.

Noise against noise: stochastic label noise helps combat inherent label noise

no code implementations ICLR 2021 Pengfei Chen, Guangyong Chen, Junjie Ye, Jingwei Zhao, Pheng-Ann Heng

The noise in stochastic gradient descent (SGD) provides a crucial implicit regularization effect, previously studied in optimization by analyzing the dynamics of parameter updates.

Beyond Class-Conditional Assumption: A Primary Attempt to Combat Instance-Dependent Label Noise

1 code implementation10 Dec 2020 Pengfei Chen, Junjie Ye, Guangyong Chen, Jingwei Zhao, Pheng-Ann Heng

In this work, we present a theoretical hypothesis testing and prove that noise in real-world dataset is unlikely to be CCN, which confirms that label noise should depend on the instance and justifies the urgent need to go beyond the CCN assumption. The theoretical results motivate us to study the more general and practical-relevant instance-dependent noise (IDN).

Robustness of Accuracy Metric and its Inspirations in Learning with Noisy Labels

1 code implementation8 Dec 2020 Pengfei Chen, Junjie Ye, Guangyong Chen, Jingwei Zhao, Pheng-Ann Heng

For validation, we prove that a noisy validation set is reliable, addressing the critical demand of model selection in scenarios like hyperparameter-tuning and early stopping.
