Advanced Equalization in 112 Gb/s Upstream PON Using a Novel Fourier Convolution-based Network

no code implementations4 May 2024 Chen Shao, Elias Giacoumidis, Patrick Matalla, Jialei Li, Shi Li, Sebastian Randel, Andre Richter, Michael Faerber, Tobias Kaefer

We experimentally demonstrate a novel, low-complexity Fourier Convolution-based Network (FConvNet) based equalizer for 112 Gb/s upstream PAM4-PON.

A Novel Machine Learning-based Equalizer for a Downstream 100G PAM-4 PON

no code implementations25 Apr 2024 Chen Shao, Elias Giacoumidis, Shi Li, Jialei Li, Michael Faerber, Tobias Kaefer, Andre Richter

A frequency-calibrated SCINet (FC-SCINet) equalizer is proposed for down-stream 100G PON with 28. 7 dB path loss.

56 GBaud PAM-4 100 km Transmission System with Photonic Processing Schemes

no code implementations17 May 2021 Irene Estébanez, Shi Li, Janek Schwind, Ingo Fischer, Stephan Pachnicke, Apostolos Argyris

In this work, we show that the effectiveness of the internal fading memory depends significantly on the properties of the signal to be processed.

Estimating Stochastic Linear Combination of Non-linear Regressions Efficiently and Scalably

no code implementations19 Oct 2020 Di Wang, Xiangyu Guo, Chaowen Guan, Shi Li, Jinhui Xu

To the best of our knowledge, this is the first work that studies and provides theoretical guarantees for the stochastic linear combination of non-linear regressions model.

Robust High Dimensional Expectation Maximization Algorithm via Trimmed Hard Thresholding

no code implementations19 Oct 2020 Di Wang, Xiangyu Guo, Shi Li, Jinhui Xu

In this paper, we study the problem of estimating latent variable models with arbitrarily corrupted samples in high dimensional space ({\em i. e.,} $d\gg n$) where the underlying parameter is assumed to be sparse.

Consistent $k$-Median: Simpler, Better and Robust

1 code implementation13 Aug 2020 Xiangyu Guo, Janardhan Kulkarni, Shi Li, Jiayi Xian

In this paper we introduce and study the online consistent $k$-clustering with outliers problem, generalizing the non-outlier version of the problem studied in [Lattanzi-Vassilvitskii, ICML17].

Facility Location Problem in Differential Privacy Model Revisited

no code implementations NeurIPS 2019 Yunus Esencayi, Marco Gaboardi, Shi Li, Di Wang

On the negative side, we show that the approximation ratio of any $\epsilon$-DP algorithm is lower bounded by $\Omega(\frac{1}{\sqrt{\epsilon}})$, even for instances on HST metrics with uniform facility cost, under the super-set output setting.

Distributed k-Clustering for Data with Heavy Noise

no code implementations NeurIPS 2018 Shi Li, Xiangyu Guo

In this paper, we improve the number of outliers to the best possible $(1+\epsilon)z$, while maintaining the $O(1)$-approximation ratio and independence of communication cost on $z$.
