3 NumPy Tricks for Numerical Performance - KDnuggets
In this article, we will cover three essential NumPy tricks to optimize your code: vectorization and broadcasting, in-place operations, and leveraging memory views instead of copies.
To optimize, you must write code using native universal functions (ufuncs) and broadcasting.
When working with very large arrays (e.g. millions of entries), allocating and garbage-collecting these temporary intermediate arrays creates substantial overhead.
