Unified Multi-modal Diagnostic Framework with Reconstruction Pre-training and Heterogeneity-combat Tuning

1 code implementation9 Apr 2024 Yupei Zhang, Li Pan, Qiushi Yang, Tan Li, Zhen Chen

Specifically, to enhance the representation abilities of vision and language encoders, we propose the Multi-level Reconstruction Pre-training (MR-Pretrain) strategy, including a feature-level and data-level reconstruction, which guides models to capture the semantic information from masked inputs of different modalities.

Truncated Non-Uniform Quantization for Distributed SGD

no code implementations2 Feb 2024 Guangfeng Yan, Tan Li, Yuanzhang Xiao, Congduan Li, Linqi Song

To address the communication bottleneck challenge in distributed learning, our work introduces a novel two-stage quantization strategy designed to enhance the communication efficiency of distributed Stochastic Gradient Descent (SGD).

Improved Quantization Strategies for Managing Heavy-tailed Gradients in Distributed Learning

no code implementations2 Feb 2024 Guangfeng Yan, Tan Li, Yuanzhang Xiao, Hanxu Hou, Linqi Song

We consider a general family of heavy-tail gradients that follow a power-law distribution, we aim to minimize the error resulting from quantization, thereby determining optimal values for two critical parameters: the truncation threshold and the quantization density.

Privacy-Preserving Communication-Efficient Federated Multi-Armed Bandits

no code implementations2 Nov 2021 Tan Li, Linqi Song

Our bandit learning algorithms are based on epoch-wise sub-optimal arm eliminations at each agent and agents exchange learning knowledge with the server/each other at the end of each epoch.

Distributed Thompson Sampling

no code implementations3 Dec 2020 Jing Dong, Tan Li, Shaolei Ren, Linqi Song

To further improve the performance of distributed Thompson Sampling, we propose a distributed Elimination based Thompson Sampling algorithm that allow the agents to learn collaboratively.

Federated Recommendation System via Differential Privacy

no code implementations14 May 2020 Tan Li, Linqi Song, Christina Fragouli

In this paper, we are interested in what we term the federated private bandits framework, that combines differential privacy with multi-agent bandit learning.

Quantum-enhanced least-square support vector machine: simplified quantum algorithm and sparse solutions

no code implementations5 Aug 2019 Jie Lin, Dan-Bo Zhang, Shuo Zhang, Xiang Wang, Tan Li, Wan-su Bao

We also incorporate kernel methods into the above quantum algorithms, which uses both exponential growth Hilbert space of qubits and infinite dimensionality of continuous variable for quantum feature maps.
