Small experiments with self-organizing map (SOM) in Torch7.
Let SOM use a 2D-grid in order to find a tour in the travelling salesman problem.
Consider the following species in lexical order:
antelop
ape
bat
bear
beetle
butterfly
camel
cat
crocodile
dog
dragonfly
duck
elephant
frog
giraffe
grasshopper
horse
housefly
hyena
kangaroo
lion
moskito
ostrich
pelican
penguin
pig
rabbit
rat
seaturtle
skunk
spider
walrus
Let SOM assign a natural order to objects characterized by a large number of attributes:
grasshopper
beetle
dragonfly
butterfly
moskito
housefly
spider
duck
pelican
penguin
ostrich
frog
seaturtle
crocodile
walrus
bear
hyena
dog
lion
cat
ape
skunk
rat
bat
elephant
kangaroo
rabbit
antelop
horse
pig
camel
giraffe
Note for example that the insects are now sorted close together.
