MurmurHash3 https://code.google.com/p/smhasher/

Project description

murmurhash is a fast hash function ::
>>> import featurehash
    >>> featurehash.hash("abc")  #return the hashcode of the string "abc"
            -1277324294
    >>> featurehash.transform_feature("abc")   #return the code and the sign of hashcode;the code is equal to "hashcode mod 8388608(2^23) + 1"
            (2255879, -1.0)
    >>> featurehash.transform_features(["abc","edf","efd","123","efd"]) #pass a sequence to the function,return the sorted unique feature code.
            [124, 2255879, 3759816, 8023169]
    >>> featurehash.transform_features(["abc","edf","efd","123","efd"],8388607) #pass a sequence and upper_bound;upper_bound default 8388608(2^23)
    [124, 2256031, 3760024, 8023393]
    >>> featurehash.transform_features(["abc","edf","efd","123","efd"],8388607,0) #pass a sequence , upper_bound and min value; min value default 1;
    [123, 2256030, 3760023, 8023392]
    >>> featurehash.transform_features(["abc","edf","efd","123","efd"],8388607,1,1) #pass a sequence , upper_bound, min value and seed; seed value default 0;the same application must must the same seed,ensure the consistent value.
