Over eight months, Psho contributed to the google-ai-edge/ai-edge-quantizer and tensorflow/tensorflow repositories, building advanced quantization features and optimizing model evaluation workflows. He developed and refactored quantization algorithms, including blockwise and Hadamard rotation methods, and enhanced dequantization routines to support dynamic shapes and custom operators. Using Python and C++, Psho focused on modular code organization, robust unit testing, and performance tuning, addressing both feature expansion and bug fixes. His work improved edge model efficiency, maintainability, and test coverage, while also upgrading dependency management and refining static quantization policies to ensure reliable deployment across diverse machine learning environments.

Month: 2025-10 focused on delivering quantization improvements in google-ai-edge/ai-edge-quantizer to boost edge model efficiency and reliability. Delivered blockwise dequantization in AEQ with block-size aware uniform_dequantize, and refined static quantization policy by removing EMBEDDING_LOOKUP from the allowlist. These changes are supported by targeted tests to ensure correctness and guard against regressions.
