Part 9/12:
Applying jit compiles functions just-in-time, yielding massive performance improvements. For example, a baseline softmax operation took around 14 milliseconds, but after JIT compilation, it dropped to under 8 milliseconds—a 50% boost. Such gains are invaluable in training large models.
Automatic Vectorization (vmap)
Transforming a loop-based implementation into a vectorized operation is made effortless with vmap. Instead of manually rewriting code to handle batching, vmap automates this process, boosting efficiency by factors of hundreds in some cases.
