Issues With Existing Clustering Techniques
- Current clustering techniques do not address all the requirements adequately.
- Dealing with large number of dimensions and large number of data items can be problematic because of time complexity;
- Effectiveness of the method depends on the definition of “distance” (for distance based clustering)
- If an obvious distance measure doesn’t exist we must “define” it, which is not always easy, especially in multidimensional spaces.
- The result of the clustering algorithm (that in many cases can be arbitrary itself) can be interpreted in different ways.

Famous quotes containing the words issues, existing and/or techniques:
“The current flows fast and furious. It issues in a spate of words from the loudspeakers and the politicians. Every day they tell us that we are a free people fighting to defend freedom. That is the current that has whirled the young airman up into the sky and keeps him circulating there among the clouds. Down here, with a roof to cover us and a gasmask handy, it is our business to puncture gasbags and discover the seeds of truth.”
—Virginia Woolf (18821941)
“The history of all hitherto existing society is the history of class struggles.”
—Karl Marx (18181883)
“It is easy to lose confidence in our natural ability to raise children. The true techniques for raising children are simple: Be with them, play with them, talk to them. You are not squandering their time no matter what the latest child development books say about purposeful play and cognitive learning skills.”
—Neil Kurshan (20th century)
