Top School

Bryan Perozzi is a researcher-practitioner who builds scalable neural methods for learning expressive representations of social relationships and natural language, with 11 years of industry experience and a strong academic track record of 20+ peer-reviewed papers at top ML and data mining venues. He designs algorithms used for prediction, pattern discovery, and anomaly detection on large graph-structured data and has translated that research into production-grade systems. Bryan is an active open-source contributor—most notably enhancing the influential DeepWalk project for graph embeddings and improving graph sampling and RDF support in TensorFlow GNN—demonstrating a focus on usability and scalability. Based in New York, he blends academic rigor with practical engineering, having worked in data science before the term was mainstream. He favors solutions that scale in memory and compute, evidenced by work on parallelized walk generation and optimized sampling pipelines. Bryan brings a rare combination of deep theoretical insight and hands-on system-building to complex networked-data problems.

TensorFlow GNN is a library to build Graph Neural Networks on the TensorFlow platform.

Role in this project:

ML Engineer

Contributions:21 commits, 1 push, 15 comments in 1 year 2 months

Contributions summary:Bryan primarily contributed to the TensorFlow GNN library by modifying the graph sampling components. Their work involved implementing a uniform random sampling strategy, enhancing existing sampling methods, and improving the validation checks and error messages related to feature sizes. The changes also included updates to the sampling spec proto definition and adjustments to the schema augmentations, demonstrating a focus on improving the flexibility and user-friendliness of the sampling pipeline. The user also added a triple converter for RDF-style input.
