Relational Generative Topographic Map

The generative topographic mapping (GTM) has been proposed as a statistical model to represent high dimensional data by means of a sparse lattice of points in latent space, such that visualization, compression, and data inspection become possible. Original GTM is restricted to Euclidean data points in a vector space. Often, data are not explicitly embedded in a Euclidean vector space, rather pa...

Maximum Likelihood Topographic Map Formation

We introduce a new unsupervised learning algorithm for kernel-based topographic map formation of heteroscedastic gaussian mixtures that allows for a unified account of distortion error (vector quantization), log-likelihood, and Kullback-Leibler divergence.

Texture based recognition of topographic map symbols

This paper introduces a method that is able to assign the symbols of vectorized maps into polygon attributes. It reduces the required storage space of the database by removing the corresponding polygons from the vectorized data model. This procedure is presented with optimized pattern matching on the raster image source of the map, where the symbols are handled as special textures. This method ...

Synaptic Rewiring for Topographic Map Formation

A model of topographic map development is presented which combines both weight plasticity and the formation and elimination of synapses as well as both activity-dependent and -independent processes. We statistically address the question of whether an activity-dependent process can refine a mapping created by an activity-independent process. A new method of evaluating the quality of topographic ...
