We first performed hierarchical stability analysis of the Chaotic Neural Network model (CNN) according to the structure of invariant subspaces. Irregular transition between two attractor ruins with positive maximum Lyapunov exponent was triggered by the blowout bifurcation of the attractor spaces, and was associated with riddled basins structure. We secondly modeled two autonomous learnings, Hebbian learning and spike-timing-dependent plasticity (STDP) rule, and simulated the effect on the chaotic itinerancy state of CNN. Hebbian learning increased the residence time on attractor ruins, and produced novel attractors in the minimum higher-dimensional subspace. It also augmented the neuronal synchrony and established the uniform modularity in chaotic itinerancy. STDP rule reduced the residence time on attractor ruins, and brought a wide range of periodicity in emerged attractors, possibly including strange attractors. Both learning rules selectively destroyed and preserved the specific invariant subspaces, depending on the neuron synchrony of the subspace where the orbits are situated. Computational rationale of the autonomous learning is discussed in connectionist perspective.<\/jats:p>","DOI":"10.1142\/s0218127415500546","type":"journal-article","created":{"date-parts":[[2015,5,4]],"date-time":"2015-05-04T06:52:15Z","timestamp":1430722335000},"page":"1550054","source":"Crossref","is-referenced-by-count":7,"title":["Synthetic Modeling of Autonomous Learning with a Chaotic Neural Network"],"prefix":"10.1142","volume":"25","author":[{"given":"Masatoshi","family":"Funabashi","sequence":"first","affiliation":[{"name":"Sony Computer Science Laboratories, Inc., 3-14-13 Higashi-Gotanda, Shinagawa-ku, Tokyo 141-0022, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2015,5,3]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1016\/S0893-6080(96)00061-5"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5193(84)80005-3"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1016\/0375-9601(85)90256-7"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1016\/0375-9601(90)90136-C"},{"key":"rf6","doi-asserted-by":"publisher","DOI":"10.1207\/s15327647jcd0501_6"},{"key":"rf7","unstructured":"K.
