# Evidence: Memory, rematerialization, and optimization tradeoffs

Copy this template into your own portfolio and fill it after running your modified exercise.

## Evidence required

Keep the plain/rematerialized gradient and HVP comparisons, saved-residual counts, compiler-memory observations and synchronized timings. Explain why fewer residuals do not guarantee lower measured memory.
