In this phase, we evolved an artificial life population with a new brain architecture. The agents have sufficient intelligence to discover patterns in data and to make survival decisions based on those patterns. The species uses diploid reproduction, Hebbian learning, and Kohonen self-organizing maps, in combination with novel techniques such as using pattern-rich data as the environment and framing the data analysis as a survival problem for artificial life. The first generation of agents mastered the pattern discovery task well enough to thrive. Evolution further adapted the agents to their environment by making them a little more pessimistic, and also by making their brains more efficient.<\/jats:p>","DOI":"10.1162\/artl_a_00074","type":"journal-article","created":{"date-parts":[[2012,9,1]],"date-time":"2012-09-01T19:07:24Z","timestamp":1346526444000},"page":"399-423","source":"Crossref","is-referenced-by-count":4,"title":["Wains: A Pattern-Seeking Artificial Life Species"],"prefix":"10.1162","volume":"18","author":[{"given":"Amy","family":"de Buitl\u00e9ir","sequence":"first","affiliation":[{"name":"Athlone Institute of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Russell","sequence":"additional","affiliation":[{"name":"Athlone Institute of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark","family":"Daly","sequence":"additional","affiliation":[{"name":"Athlone Institute of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"281","reference":[{"key":"R1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-34956-3"},{"key":"R2","doi-asserted-by":"publisher","DOI":"10.1126\/science.3898363"},{"key":"R3","doi-asserted-by":"crossref","DOI":"10.1093\/oso\/9780195131581.001.0001","volume-title":"Swarm intelligence: From natural to artificial systems.","author":"Bonabeau E.","year":"1999"},{"key":"R4","doi-asserted-by":"publisher","DOI":"10.1007\/BF00426023"},{"key":"R5","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4419-0522-2"},{"key":"R7","volume-title":"Positive feedback as a search strategy","author":"Dorigo M.","year":"1991"},{"key":"R8","doi-asserted-by":"publisher","DOI":"10.1086\/412317"},{"key":"R9","doi-asserted-by":"publisher","DOI":"10.1007\/s10994-009-5156-0"},{"key":"R10","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-19721-5"},{"key":"R11","volume-title":"Creation: Life and how to make it.","author":"Grand S.","year":"2001"},{"issue":"1","key":"R12","doi-asserted-by":"crossref","first-page":"39","DOI":"10.1023\/A:1010042522104","volume":"1","author":"Grand S.","year":"1997","journal-title":"Autonomous Agents and Multi-Agent Systems"},{"key":"R14","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.87.9.3566"},{"key":"R15","volume-title":"Data mining: Concepts and techniques.","author":"Han J.","year":"2011"},{"key":"R16","volume-title":"The organization of behavior: A neuropsychological theory.","author":"Hebb D.
