A growing self-organizing map (GSOM) is a growing variant of the popular self-organizing map (SOM). The GSOM was developed to address the issue of identifying a suitable map size in the SOM. It starts with a minimal number of nodes (usually 4) and grows new nodes on the boundary based on a heuristic. By using the value called Spread Factor (SF), the data analyst has the ability to control the growth of the GSOM.
All the starting nodes of the GSOM are boundary nodes, i.e. each node has the freedom to grow in its own direction at the beginning. (Fig. 1) New Nodes are grown from the boundary nodes. Once a node is selected for growing all its free neighboring positions will be grown new nodes. The figure shows the three possible node growth options for a rectangular GSOM.
The GSOM process is as follows:

You see inside
You see inside
You read my mind
You read my mind
You survived a hellish dream
Now the light can mend the seams
But your will wraps tight around
Watch the sky come crashing down
You breathe
Believe
You touch
Won't face I need you so much
Embrace
Encase
I fear
Your love for me is so clear
You survived a hellish dream
Now the light can mend the seams
But your will wraps tight around
Watch the sky come crashing down
I arrived on foreign land
With no one to hold my hand
But my guide came shining through
From the fog alone stood you
A love that's so defined
You'll never wake the newness that can be
A happiness so kind
Mistaken for seductive falsity
You breathe
Believe
You touch
Won't face I need you so much
Embrace
Encase
I fear
Your love for me is so clear
A love that's so defined
You'll never wake the newness that can be
A happiness so kind
Mistaken for seductive falsity
Just knowing that you're mine
Erases all reverse complexity
The emptiness unwinds
An unexpected flexibility
You survived a hellish dream
Now the light can mend the seams
But your will wraps tight around
