We constructed filtered simplicial complexes using α as a filtration parameter (scaled by deviation from w*). Persistent homology reveals topological holes, which we interpret as structural signatures of complementary information distribution 🕸️

Persistence barcodes for the simplicial complexes in each season, including the simplices of individual core ranges formed by decreasingly redundant interactions.

We found that in some cases, the observed w values closely follow the predicted convex decreasing function of set size n. Smaller sets (2-6 individuals) show higher variance, suggesting this range is most dynamic for knowledge complementarity.

Scaling relationship between the number of individual core ranges and its intersection/union ratio, w. Each dot corresponds to a particular set of a given number of individuals. The solid black line corresponds to the scaling relationship.

We derived an optimal intersection/union ratio (w*) that maximizes information transfer between n individuals: w* = 1/(n+1) This balances redundant overlap (coincidence opportunities) with unique knowledge (areas known exclusively by subsets).

Conceptual illustration of the degree of redundancy and uniqueness shown by four hypothetical overlapping individual core ranges.

We estimated individual core ranges (60% utilization distributions) from 6 years of location data in Yucatan, Mexico. We assumed that these core ranges represent an individual's spatial knowledge for a given season, while partial overlaps create opportunities for information transfer.

Two sets of overlapping core ranges showing both redundant and unique areas

Always uniquely funny and inspiring. Here at one of the first conferences I attended as a grad student, the Animal Social Complexity and Intelligence conference in Chicago, in 2000. Thank you Jane Goodall.

Very happy to host @estebanmoro.bsky.social at UNAM. He'll be giving a talk at IIMAS' coloquium and participating in an urban mobility and social network discussion at C3-UNAM. More information: www.iimas.unam.mx/event/market... c3.unam.mx/conferencias...

We show that collective learning about the best foraging sites is enhanced by agents foraging widely (using Lévy movement strategies) and exchanging some information about the best sites with other agents. Collaboration with Andrea Falcón, Max Aldana and Denis Boyer. dx.plos.org/10.1371/jour...

I kind of like this one, lately (from doi.org/10.1111/cogs...)

“Fringe” is in the eye of the beholder. Realigning interaction-centered approaches from across disparate fields can fuel a figure-ground reversal in the cognitive sciences, here illustrated with an assortment of subfields around the classic hexagon: 1 interactional linguistics (Clift, 2016; Schegloff, Ochs, & Thompson, 1996); 2 grammars of language use (Ameka & Terkourafi, 2019; Gregoromichelaki et al., 2022); 3 cognitive ethnography (Hutchins, 1995); 4 situated action (Suchman, 2007); 5 social and second person neuroscience (Schilbach et al., 2013; Wheatley, Boncz, Toni, & Stolk, 2019); 6 joint action (Shockley, Richardson, & Dale, 2009; Vesper, Butterfill, Knoblich, & Sebanz, 2010); 7 dialogue modeling (Schlangen & Skantze, 2011); 8 embodied interaction (Bennett et al., 2021); 9 discursive psychology (Edwards, 1997); 10 ecological psychology (Rączaszek-Leonardi, Nomikou, Rohlf

And one year after that, in 1946, J.L. Borges published the same idea in "On exactitude in science" kwarc.info/teaching/TDM/Borges.pdf (De Viajes de Varones Prudentes de Suarez Miranda, libro IV, cap. XIV, Lérida, 1658. Citado por Jorge Luis Borges, Historia Universal de la infamia «etc».)

A jewel of a paper by Rosenblueth, Wiener and Bigelow. Contains lots of insight into purpose and prediction. Hard to believe it was published in 1943. www.jstor.org/stable/pdf/184878.pdf

Just spent an incredible time at the Diverse Intelligences Summer Institute in beautiful St. Andrews, Scotland. Such an inspiring and free exchange of ideas!
