Project Experience

Hardware [Main Skill]

Sep. 2016 - March. 2018 GNA: Reconfigurable and efficient architecture for generative network acceleration

• This study aims to accelerate a generative network, which includes CONV layers, DeCONV layers and residual blocks. It achieves an energy efficiency of 2.05 TOPS/W with 61% higher PE utilization than traditional methods in generative network acceleration.

• GNA is my first study toward a deep learning accelerator.

• Published in TCAD (IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems), 2018 (First Author).

April. 2018 - Jul. 2019 Survey: Research on low-power neural network computing accelerator

• This study aims to propose a reconfigurable hardware architecture to meet the flexibility requirements of a neural network.

• This study is rewarded as one of the excellent scientific papers in the field of electronic information (2021) by the Chinese Institute of Electronics. Publish in SCIENTIA SINICA Informationis, 2019 (First Author)

• It is collaborative work with Prof. Yuan Xie.

Spet. 2022 - May. 2023 Sparse-Sparse Matrix Multiplication Accelerator

• This study proposes a Disperse-Merge Product (DMP) SpMSpM dataflow and a DMP-based SpMSpM accelerator (DMSA) architecture. The DMP divides the workload into balanced flows, generates partial matrices based on these flows, and merges the partial results in a parallel and pipelined manner.

• Deployed on the Xilinx Zynq-UltraScale ZCU106, it achieves a speedup of 4.8X compared to the latest SpMSpM accelerators with similar resources on the same FPGA platform.

• Results are published on ASP-DAC’23, IEEE ICCE’23. We are also considering extending this work to further IEEE Trans journals!

May. 2023 - Aug. 2024 Graph Neural Network Accelerator

• I am doing a high-performance GNN accelerator, which includes how to accelerate SpMM/GeMM computations. It is accepted by ISCA’25.

Algorithm [Sub-skill]

Sep. 2021 - Sep.2022: TT-MLP: Tensor Train Decomposition on Deep MLPs

• This study aims to combine tensor-train decomposition with deep MLPs.

• In the evaluation, the proposed method showed a better trade-off than conventional TTD methods on ImageNet-1K and achieved a 0.56% higher inference accuracy with a 15.44% memory reduction on Cifar-10.

• This study is my first try at deep learning algorithms, especially when doing a remote study under a serious Covid-19 situation.

• Results are published in IEEE CoolChip’23 (won the Best Poster) and IEEE Access’23.

May.2022 - April.2023: Strong Lottery Tickets(SLT) on Graph neural networks(GNNs)

• The Strong Lottery Ticket Hypothesis (SLTH) demonstrates the existence of high-performing subnetworks within a randomly initialized model, discoverable through pruning a convolutional neural network (CNN) without any weight training. This work extended SLTH from CNNs to GNNs.

• This work utilizes Multicoated Supermasks (M-Sup), a scalar pruning mask method, and implements it in GNNs by proposing a strategy for setting its pruning thresholds adaptively. In the context of deep GNNs, this research uncovers the existence of untrained recurrent networks, which exhibit performance on par with their trained feed-forward counterparts.

• Through the evaluation of various datasets, including the Open Graph Benchmark (OGB), this work establishes a triple-win scenario for SLTH-based GNNs: by achieving high sparsity, competitive performance, and high memory efficiency with up to 98.7% reduction, it demonstrates suitability for energy-efficient graph processing.

April.2023 - Prensent: Graph-Transformer

• The Graph-Transformer is a prominent topic in recent GNN research. I am currently conducting surveys on this subject.
