CAD Re-parameterization active

Our goal is to build a tool for automatically reparameterizing 3D CAD models to facilitate seamless design exploration. We employ a neurosymbolic approach, leveraging foundational language and diffusion models to generate compelling and valid variations of the input model, and symbolic analysis to discover geometric constraints that hold across the shape class.

Pitchfork inactive

Pitchfork is an instruction selection system for high-performance fixed-point computing, centered around a new fixed-point IR (FPIR). Pitchfork uses a set of term-rewriting systems to lift the input code to FPIR before lowering it to target fixed-point instructions. Offline synthesis is used to infer new rules that enable cheap semantic reasoning at compile time.

Rake inactive

Rake is a new tool that uses program-synthesis to transform lower-level DSL IRs to complex high-level instruction sets found in modern hardware, such as the Hexagon HVX ISA.

Dexter inactive

Dexter is a new tool to automatically translate image processing functions from a low-level language to a high-level domain-specific language (DSL), allowing such functions to leverage the cross-platform optimizations enabled by DSLs. This project is an outcome of my internship at Adobe and is done in collaboration with Shoaib Kamil and Jonathan Ragan-Kelley.
