Cool stuff. I'm probably missing this, but where in the code are you ensuring that all feature vectors have the same number of dimensions (i.e., length)? From what I can tell, for a text value from sqlite, the code converts each char to a float and stores those bits in the vector. This could work if the hamming distance accounts for different length vectors, but that function appears to assume they are the same. Thanks for the clarification.

Internally vectors (at least float vectors) get converted to float * arrays, where the vectors lengths are manually checked. If you provide a vector in JSON form, then it parses that JSON into a float * array. Vectors must be the same length for distance operations.
