PROFILE
Hyukjin Jeong
Over eight months, Jeong contributed to the Samsung/ONE repository by developing and optimizing quantization workflows, data type support, and model transformation passes. He engineered axis-aware MX quantization across the stack, enhanced resource management, and improved test automation for quantized models. Using C++ and Protocol Buffers, Jeong refactored quantization propagation in the Luci compiler to a phase-based model, enabling more reliable and maintainable quantized inference. His work included extending schema definitions, implementing robust data generation for uint4 paths, and ensuring correctness in shape and quantization transformations. These efforts improved model reliability, diagnostics, and cross-component interoperability within embedded and machine learning systems.
