Examples of pkann

Classify input image input.tif with an Artificial Neural Network using one hidden layer with 5 neurons. A training sample that is provided as an OGR vector dataset. It contains all features (same dimensionality as input.tif) in its fields (please check pkextract on how to obtain such a file from a "clean" vector file containing locations only). A two-fold cross validation (cv) is performed (output on screen).

pkann -i input.tif -t training.sqlite -o output.tif --nneuron 5 -cv 2

Same example as above, but use two hidden layers with 15 and 5 neurons respectively

pkann -i input.tif -t training.sqlite -o output.tif --nneuron 15 --neuron 5 -cv 2
