While limited to one ABM, this work fills a critical gap in the ABM calibration literature, providing the first structured comparison of DA and LBI for latent state inference.

Kudos to Marco, Corrado, and Gianmarco for such a wonderful collaboration!

Hope you enjoy it

Comparing Data Assimilation and Likelihood-Based Inference on Latent State Estimation in Agent-Based Models

In this paper, we present the first systematic comparison of Data Assimilation (DA) and Likelihood-Based Inference (LBI) in the context of Agent-Based Models (ABMs). These models generate observable t...

Almost back from #ic2s2 (thanks Lufthansa). The most positively-surprising impression from the conference, almost a decade after the first edition, is how much the discipline has coalesced. In 2016, it was easy to distinguish a paper authored by computer scientists vs sociologists. Not so easy now!

Gianmarco De Francisci Morales @gdfm.bsky.social · Jul 23

Agreed. And to do so we need to stop using tools that were developed to measure human concepts.

FOMO for #ic2s2 is hitting hard---especially for Francesco, who is bravely pretending he’s totally fine without me.

🚨Are moral judgements biased by the gender of the subject?
We find *no* direct effect when looking at Reddit!

Our causal study design is based on carefully matching similar situations that people with different genders experience (and share).
