Intrinsic Motivation in Dynamical Control Systems
Stas Tiomkin, Ilya Nemenman, Daniel Polani +1
Biological systems often choose actions without an explicit reward signal, a phenomenon known as intrinsic motivation. The computational principles underlying this behavior remain…
Generative random latent features models and statistics of natural images
Philipp Fleig, Ilya Nemenman
Complex, multivariable systems are often analyzed by grouping their constituent units into components, sometimes referred to as latent features, which afford physical or biological…
Low probability states, data statistics, and entropy estimation
Damián G. Hernández, Ahmed Roman, Ilya Nemenman
A fundamental problem in analysis of complex systems is getting a reliable estimate of entropy of their probability distributions over the state space. This is difficult because un…
Multi-dimensional structure of C. elegans thermal learning
Ahmed Roman, Konstantine Palanski, Ilya Nemenman +1
Quantitative models of associative learning that explain the behavior of real animals with high precision have turned out very difficult to construct. We do this in the context of…
Ballistic deposition with memory: a new universality class of surface growth with a new scaling law
Ahmed Roman, Ruomin Zhu, Ilya Nemenman
Motivated by recent experimental studies in microbiology, we suggest a modification of the classic ballistic deposition model of surface growth, where the memory of a deposition at…
