Connections in Math: deriving the SVD from scratch

Hi all, I have been now just writing things to consolidate some basic applied math. This is nothing advanced but just a good way to put things out and to learn by writing.

One of the things I try to do is to build things more intuitively instead of the traditional math book approach of starting from the final formalized result and giving a few formalized hints on how that object came from.

pynear 2.3 is out 🚀

pynear is a fast KNN library that doesn't make you choose between exact answers and production speed. Drop-in for scikit-learn. SIMD-accelerated. Up to 257× faster than Faiss on binary descriptors at 100% recall.

• cosine indices (exact + approximate)

• drop-in for scikit-learn (metric='cosine')

• Incredibly fast approximate IndexBinaryMultiHash with high recall (beats Faiss in some contexts)

pip install -U pynear
