What is the difference between multithreading and multiprocessing in AI?

Multithreading involves multiple threads within a single process, sharing the same memory space, while multiprocessing uses multiple processes, each with its own memory space. This can affect performance and resource management in AI applications.

Which one is better for AI tasks?

It depends on the task. Multithreading is often better for I/O-bound tasks, while multiprocessing is more suitable for CPU-bound tasks due to its ability to utilize multiple cores.

Can you give examples of when to use each?

Sure! Use multithreading for tasks like data fetching or network requests, where waiting is involved. Use multiprocessing for tasks like training machine learning models, where heavy computations are needed.

Are there any downsides to using multiprocessing?

Yes, multiprocessing can have higher overhead due to the need for inter-process communication and can consume more memory since each process has its own memory space.
