Training neural network with PARTITION=2 (random
sets) option. Functional scheme of partition procedure and process of neural network
training. Updated from article Tetko
et al., 1998.
The gray circles and left-most rectangle represent data samples (HPLC data
in original article).
There are 12 data samples in he initial training set, each sample is identified
by its position in the rectangles. Each sample can belong only to a learning
or validation set (designated by empty or black circles, respectively)
for a given neural network. Because of random partitioning between the
learning and validation sets, each sample on average participates an equal
number of times to both these sets. After ensemble learning, results are
calculated for each sample both to learning and validation sets. The leave-one-out
results for the whole data set are also calculated as proposed in Tetko
et al., 1995.The trained networks can be used to predict the test set (if available)
or the calculated models can be saved using MODELS=1
option and further retrieved to predict new data.
