Circuits with broken fibration symmetries perform core logic computations in biological networks

no code implementations23 Jun 2020 Ian Leifer, Flaviano Morone, Saulo D. S. Reis, Jose S. Andrade Jr., Mariano Sigman, Hernan A. Makse

We show that logic computational circuits in gene regulatory networks arise from a fibration symmetry breaking in the network structure.

Fading of collective attention shapes the evolution of linguistic variants

no code implementations20 Nov 2018 Diego E Shalom, Mariano Sigman, Gabriel Mindlin, Marcos A Trevisan

In the case of the Spanish past subjunctive, the spontaneous evolution of its two competing forms (ended in -ra and -se) was perturbed by the appearance of the Royal Spanish Academy in 1713, which enforced the spelling of both forms as perfectly interchangeable variants (4), at a moment in which the -ra form was dominant (5).

Towards a more flexible Language of Thought: Bayesian grammar updates after each concept exposure

no code implementations17 May 2018 Pablo Tano, Sergio Romano, Mariano Sigman, Alejo Salles, Santiago Figueira

Recent approaches to human concept learning have successfully combined the power of symbolic, infinitely productive rule systems and statistical learning to explain our ability to learn new concepts from just a few examples.

Corpus specificity in LSA and Word2vec: the role of out-of-domain documents

no code implementations WS 2018 Edgar Altszyler, Mariano Sigman, Diego Fernandez Slezak

In the present article we investigate whether LSA and Word2vec capacity to identify relevant semantic dimensions increases with size of corpus.

The ontogeny of discourse structure mimics the development of literature

no code implementations27 Dec 2016 Natalia Bezerra Mota, Sylvia Pinheiro, Mariano Sigman, Diego Fernandez Slezak, Guillermo Cecchi, Mauro Copelli, Sidarta Ribeiro

In literature, monotonic asymptotic changes over time were remarkable: While lexical diversity, long-range recurrence and graph size increased away from near-randomness, short-range recurrence declined, from above to below random levels.
