"Slow Feature Analysis (SFA) is an efficient algorithm for \nlearning input-output functions that extract the most slowly varying features from a quickly varying signal. It \nhas been successfully applied to the unsupervised learning \nof translation-, rotation-, and other invariances in a \nmodel of the visual system, to the learning of complex cell\nreceptive fields, and, combined with a sparseness \nobjective, to the self-organized formation of place cells \nin a model of the hippocampus.\n\nIn order to arrive at a biologically more plausible implementation of this learning rule, we consider analytically how SFA could be realized in simple linear continuous and spiking model neurons. It turns out that for the continuous model neuron SFA can be implemented by means of a modified version of standard Hebbian learning. In this framework we provide a connection to the trace learning rule for invariance learning. We then show that for Poisson neurons spike-timing-dependent plasticity (STDP) with a specific learning window can learn the same weight distribution as SFA. Surprisingly, we find that the appropriate learning rule reproduces the typical STDP learning window. The shape as well as the timescale are in good agreement with what has been measured experimentally. This offers a completely novel interpretation for the functional role of spike-timing-dependent plasticity in physiological neurons. "^^ . "2006-12" . . . . . . . . . . . . . . "Christian"^^ .
