Duality between low-rank decoding and low-rank functional identification. Duality between low-rank decoding of a stimulus encoded by a population of complex cells and low-rank functional identification of complex cells. (A) The low-rank decoding algorithm assumes that the encoded stimulus can be written as \(u_{2}(t_{1};t_{2})=u_{1}(t_{1})u _{1}(t_{2})\). (B) Functional identification of a complex cell assumes that the structure of the DSP is low rank, that is, \(\mathcal{P}_{2}h _{2}(t_{1};t_{2}) = \sum_{n=1}^{N} \mathcal{P}_{1}g^{n}_{1}(t_{1}) \mathcal{P}_{1}g^{n}_{1}(t_{2})\)
