In this paper, a novel Optimal Transport based Graph Neural Network (OT-GNN) is proposed to overcome the oversmoothing problem in unsupervised GNNs by imposing the equal-sized clustering constraints to the obtained node embeddings.

There are two well-defined clusters R. Rojas: Neural Networks, Springer-Verlag, Berlin, 1996 106 5 Unsupervised Learning and Clustering Algorithms –10 1 centered at −1 and 1 respectively. This clustering must be identified by the networkshown in Figure 5.4, which consists oftwo units, eachwith one weight. A possible solution is α= −1 and β= 1.

A good example of Unsupervised Learning is clustering, where we find clusters within the data set based on the underlying data itself. The field ...

Here we develop a spiking neural network model for neuromorphic hardware that uses spike timing-dependent plasticity and lateral inhibition to perform unsupervised clustering.

Neural networks are widely used in unsupervised learning in order to learn better representations of the input data. For example, given a set of text ...

However, to use these systems in applications, we need "neuromorphic algorithms" that can run on them. Here we develop a spiking neural network model for neuromorphic hardware that uses spike timing-dependent plasticity and lateral inhibition to perform unsupervised clustering.

03.03.2015 · A SOM is a NN that has a set of neurons connected to form a topological grid (usually rectangular). When some pattern is presented to an SOM, the neuron with closest weight vector is considered a winner and its weights are adapted to the pattern, as well as the weights of its neighbourhood. In this way an SOM naturally finds data clusters.

Among neural network models, the self-organizing map (SOM) and adaptive resonance theory (ART) are commonly used in unsupervised ...

Generally, unsupervised learning or self-organized learning finds regularities in the data represented by the examples. Clustering methods such as ...

Next, unsupervised graph neural networks are elaborated. Finally, exiting methods, which combine clustering and embedding, are introduced. Graph Neural Networks: Graph Neural Networks (GNNs) [1], [2] aim at applying the expressive representation power of deep learning to irregular data, i.e, graphs.

These properties are often easily achieved analytically but are harder to enforce when working in a stochastic optimization (e.g. neural network) ...
