Could you build this?
No This is novel algorithmic research and specialized low-level systems programming implementing an exact gradient Connectionist Temporal Classification (CTC) loss kernel.
What it would actually take: Implementing this requires writing custom PyTorch C++/CUDA extensions with manual forward and backward autodiff passes to optimize GPU register and shared memory allocation. The primary challenge is deriving the exact mathematical formulation for loss and gradient equivalence under dynamic vocabulary pruning while preventing linear activation memory scaling. It demands deep expertise in GPU architecture, high-performance computing, and speech recognition loss algorithms.
