Deep learning for non-parameterized MEMS structural design

no code implementations Nature 2022 Ruiqi Guo, Fanping Sui, Wei Yue, Zekai Wang, Sedat Pala, Kunying Li, Renxiao Xu, Liwei Lin

With reasonable training, our deep learning neural network becomes a high-speed, high-accuracy calculator: it can identify the flexural mode frequency and the quality factor 4. 6 × 10 times and 2. 6 × 10 times faster, respectively, than conventional numerical simulation packages, with good accuracies of 98. 8 ± 1. 6% and 96. 8 ± 3. 1%, respectively.

A Unified Model for Zero-shot Music Source Separation, Transcription and Synthesis

1 code implementation7 Aug 2021 Liwei Lin, Qiuqiang Kong, Junyan Jiang, Gus Xia

We propose a unified model for three inter-related tasks: 1) to \textit{separate} individual sound sources from a mixed music audio, 2) to \textit{transcribe} each sound source to MIDI notes, and 3) to\textit{ synthesize} new pieces based on the timbre of separated sources.

Guided learning for weakly-labeled semi-supervised sound event detection

1 code implementation6 Jun 2019 Liwei Lin, Xiangdong Wang, Hong Liu, Yueliang Qian

Instead of designing a single model by considering a trade-off between the two sub-targets, we design a teacher model aiming at audio tagging to guide a student model aiming at boundary detection to learn using the unlabeled data.

Specialized Decision Surface and Disentangled Feature for Weakly-Supervised Polyphonic Sound Event Detection

1 code implementation24 May 2019 Liwei Lin, Xiangdong Wang, Hong Liu, Yueliang Qian

In this paper, a special decision surface for the weakly-supervised sound event detection (SED) and a disentangled feature (DF) for the multi-label problem in polyphonic SED are proposed.

A Novel Fuzzy Search Approach over Encrypted Data with Improved Accuracy and Efficiency

no code implementations27 Apr 2019 Jinkun Cao, Jinhao Zhu, Liwei Lin, Zhengui Xue, Ruhui Ma, Haibing Guan

To avoid privacy leaks, outsourced data usually is encrypted before being sent to cloud servers, which disables traditional search schemes for plain text.
