One of the easiest ways to construct an LSH family is by bit sampling. This approach works for the Hamming distance over d-dimensional vectors . Here, the family of hash functions is simply the family of all the projections of points on one of the coordinates, i.e., , where is the th coordinate of . A random function from simply selects a random bit from the input point. This family has the following parameters: , .
