... goal, including ran- dom initialization (Fred and Jain, 2002), feature ex- traction based onrandom projection (Fern andBrod- ley, 2003) and the combination of sets of “weak” partitions (Topchy et ... 1990). Dimensional reduc- tion maps data in a high-dimensional space into a low-dimensional space, and improves both cluster- ing accuracy and speed. NMF is a dimensional reduction method (Xu ....

... solutions for all values of k from 1 N , and then determines the mean and standard deviation of the criterion function. Then, a score is computed for each value of k by sub- tracting the mean from ... from the criterion function, and dividing by the standard deviation. We adapt this technique by using the H2 criterion function, and limit k from 1 deltaK: P K1(k) = H2(k) − mean(H2[1 deltaK]) s...

Thus, ... similar meanings are often used in similar contexts. As it was men- tioned, we can treat a meaning of a metaphoric usage of an expression as an additional, not com- mon for the expressi...
