Ok-Topk
November 27, 2021 – December 10, 2022
Ok-Topk is a scheme for distributed training with sparse gradients. Ok-Topk integrates a novel sparse allreduce algorithm (less than 6k communication volume which is asymptotically optimal) with the decentralized parallel Stochastic Gradient Descent (SGD) optimizer, and its convergence is proved theoretically and empirically.

Eager-SGD is a decentralized asynchronous SGD. It utilizes novel partial collectives operations to accumulate the gradients across all the processes.
View ProjectCultural Fit Analysis
The candidate's projects are heavily focused on deep learning infrastructure, distributed training, and performance optimization, which aligns well with a research-heavy Data Scientist role. However, the projects are all personal, and there is only one current work experience listed with a future start date, which limits the assessment of collaborative work in a professional setting. The breadth of application domains for data science is also limited to deep learning performance, rather than diverse analytical or modeling tasks.
Soft Skills & Operational Fit
Insufficient data to assess soft skills or operational fit. No psychometric or English test scores are available.
