The Self-Organizing Map (SOM) is a famous algorithm for the unsupervised learning and visualization introduced by Teuvo Kohonen.
This study proposes the Lazy Self-Organizing Map (LSOM) algorithm
which reflects the world of worker ants.
In LSOM, three kinds of neurons exist: worker neurons, lazy neurons and indecisive neurons.
We apply LSOM to various input data set
and confirm that LSOM can obtain a more effective map reflecting the distribution state of the input data
than the conventional SOM. |
