IndexBinary backed by a float Index.
Supports adding vertices and searching them.
All queries are symmetric because there is no distinction between codes and vectors.

Add n vectors of dimension d to the index.
Vectors are implicitly assigned labels ntotal .. ntotal + n - 1
| x | input matrix, size n * d / 8 |
Implements faiss::IndexBinary.
Definition at line 35 of file IndexBinaryFromFloat.cpp.

overridevirtual |
Query n vectors of dimension d to the index.
return at most k vectors. If there are not enough results for a query, the result array is padded with -1s.
| x | input vectors to search, size n * d / 8 |
| labels | output labels of the NNs, size n*k |
| distances | output pairwise distances, size n*k |
Implements faiss::IndexBinary.

overridevirtual |
Perform training on a representative set of vectors.
| n | nb of training vectors |
| x | training vecors, size n * d / 8 |
