WebFeb 15, 2014 · Hashing using division method means h(k) = k mod m . I read that . m should not be power of 2. This is because if m = 2^p, h becomes just the p lowest-order bits of k. Usually we choose m to be a prime number not too close to a power of 2. Could someone explain with a small example the lowest order bits part? WebFeb 26, 2012 · 2. This is my first question on stackflow. As you can tell, I am new to learning algorithms and data structure. When using the division method for create a hash function (i.e. h (k) = k mod m), one is advised (e.g. by CLRS) to use a prime number not too close to a power of 2 for the divisor m. http://www.idata8.com/rpackage/FeatureHashing/hashed.model.matrix.html frankl logotherapy
