Symphony Generation with Permutation Invariant Language Model

1 code implementation10 May 2022 Jiafeng Liu, Yuanliang Dong, Zehua Cheng, Xinran Zhang, Xiaobing Li, Feng Yu, Maosong Sun

In this work, we propose a permutation invariant language model, SymphonyNet, as a solution for symbolic symphony music generation.

CWS-PResUNet: Music Source Separation with Channel-wise Subband Phase-aware ResUNet

1 code implementation9 Dec 2021 Haohe Liu, Qiuqiang Kong, Jiafeng Liu

On the MUSDB18HQ test set, we propose a 276-layer CWS-PResUNet and achieve state-of-the-art (SoTA) performance on vocals with an 8. 92 signal-to-distortion ratio (SDR) score.

Lingxi: A Diversity-aware Chinese Modern Poetry Generation System

no code implementations27 Aug 2021 Xinran Zhang, Maosong Sun, Jiafeng Liu, Xiaobing Li

We propose nucleus sampling with randomized head (NS-RH) algorithm, which randomizes the high frequency part ("head") of the predicted distribution, in order to emphasize on the "comparatively low frequency" words.

Optimal Embedding Calibration for Symbolic Music Similarity

no code implementations13 Mar 2021 Xinran Zhang, Maosong Sun, Jiafeng Liu, Xiaobing Li

In natural language processing (NLP), the semantic similarity task requires large-scale, high-quality human-annotated labels for fine-tuning or evaluation.

Improving Diversity of Neural Text Generation via Inverse Probability Weighting

no code implementations13 Mar 2021 Xinran Zhang, Maosong Sun, Jiafeng Liu, Xiaobing Li

Traditional stochastic sampling methods only focus on truncating the unreliable "tail" of the distribution, and do not address the "head" part, which we show might contain tedious or even repetitive candidates with high probability that lead to repetition loops.
