Description

Hello, I found a performance issue in the definition of encode, tensorflow_model_optimization/python/core/internal/tensor_encoding/stages/research/kashin.py, tf.cast will be calculated repeatedly during program execution, resulting in reduced efficiency. I think it should be created before the loop in encode.

Looking forward to your reply. Btw, I am very glad to create a PR to fix it if you are too busy.

Research direction

Start in tensorflow_model_optimization/python/core/internal/tensor_encoding/stages/research/kashin.py at the encode definition and inspect the tf.cast call around line 201 and its surrounding loop. Confirm how often the cast is evaluated, then verify the change with the relevant existing tests or execution path. Done means the cast is created before the loop without changing encode's behavior.
