PROFILE
Anup Kumar Singh
Worked on the Xilinx/onnx-mlir repository to enhance ONNX-MLIR’s optimization and transformation capabilities, focusing on compiler design and performance optimization using C++ and MLIR. Developed and consolidated optimization passes, expanded transformation templates for tensor operations, and improved test coverage to ensure correctness and maintainability. Introduced new features such as 5D transpose transforms, 1D-to-2D pooling conversions, and depthwise convolution optimizations, while refining pass management for more efficient compilation. Addressed diverse data layouts by supporting channel-last resizing and robust 4D shape handling. Emphasized code quality through linting, formatting, and build system improvements, contributing to a more stable and reliable codebase.
