The algorithm extends the classical framework of dimensionality reduction to the case where sensory data are acquired through an embodied agent, by grounding the metric that is at the basis of the dimensionality reduction in the sensorimotor abilities of the agent. The final objective (which was ...

The 2D plot uses MDS as the dimension reduction method. Typically, a reduction in dimensionality implies a loss of information, but the glyphs include all the high-dimensional information in the data. The purpose of using MDS is to impose some regularity on the variation in the data, so that...
Our proposed methodology consists of three main parts: (1)\ndata reparameterization via dimensionality reduction, wherein the data are\nmapped into a space where standard techniques can be used for density\nestimation and simulation; (2) inverse mapping, in which simulated points are\nmapped back...

Autoencoders fordimensionality reductionare used to compress the input into the smallest representation possible to reproduce the input with the smallest loss. "In this case, the goal is not necessarily to reproduce the input, but instead to use the smaller representation from the encoder ...
