Ecological networks of viable species with degree-dependent interaction
Hae Seong Lee, Deok-Sun Lee, Sang Hoon Lee +2
The generalized Lotka-Volterra (GLV) framework, recently advanced by dynamical mean-field theory, enables the systematic analysis of large ecological networks. When combined with s…
Reinforcement Learning for Graph Generation under a Hard Assortativity Constraint
Hoyun Choi, Junghyo Jo, Deok-Sun Lee
Generating graph ensembles with precisely controlled structural properties is central to investigating how network structure shapes function. Canonical ensembles impose constraints…
Distribution Matching Distillation without Fake Score Network
Youngjoong Kim, Deokyeong Lee, Jaesik Park
Distribution Matching Distillation (DMD) provides an effective distribution-level correction for few-step generation, while relying on an auxiliary fake-score network to track the…
Watch your neighbors: Training statistically accurate chaotic systems with local phase space information
Joon-Hyuk Ko, Andrus Giraldo, Deok-Sun Lee
Chaotic systems pose fundamental challenges for data-driven dynamics discovery, as small modeling errors lead to exponentially growing trajectory discrepancies. Since exact long-te…
Discontinuous Wealth-Gradient Transition Driving Cooperation
Hyun Gyu Lee, Hyeong-Chai Jeong, Deok-Sun Lee
The universal prevalence of cooperation is puzzling, as defection typically yields higher payoffs than cooperation, motivating searches for hidden pathways to cooperation. Here we…
Competition between group interactions and nonlinearity in voter dynamics on hypergraphs
Jihye Kim, Deok-Sun Lee, Byungjoon Min +3
Social dynamics are often driven by both pairwise (i.e., dyadic) relationships and higher-order (i.e., polyadic) group relationships, which one can describe using hypergraphs. To g…
Bifurcations and multistability in empirical mutualistic networks
Andrus Giraldo, Deok-Sun Lee
Individual species may experience diverse outcomes, from prosperity to extinction, in an ecological community subject to external and internal variations. Despite the wealth of the…
Incorporating Heterogeneous Interactions for Ecological Biodiversity
Jong Il Park, Deok-Sun Lee, Sang Hoon Lee +1
Understanding the behaviors of ecological systems is challenging given their multi-faceted complexity. To proceed, theoretical models such as Lotka-Volterra dynamics with random in…
