abstract = "Semi-supervised Learning with Graphs can achieve good results in
classification tasks even in difficult conditions. Unfortunately,
it can be slow and use a lot of memory. The first important step
of the graph-based semi-supervised learning approaches is the
construction of the graph from the data, where each data-point
usually becomes a vertex in the graph a potential problem with
large amounts of data. In this paper, we present a graph
construction method that uses an unsupervised neural network
called growing neural gas (GNG). The GNG instance presents a
intelligent stopping criteria that determines when the final
network configuration maps correctly the input- data points. With
that in mind, we use the final trained network as a reduced input
graph for the semi-supervised classification algorithm,
associating original data-points to the neurons they have
activated in the unsupervised training process.",
