"If you read only one book on the philosophy of statistics, make it this one. Otsuka’s compact yet comprehensive treatment (under 190 pages) provides a uniquely integrated view of the major statistical frameworks that shape modern data science and AI."

Our process causation paper is published in Synthese! We propose that process causation (a la Salmon, Dowe, MDC new mechanists) can be modeled using a category-theoretic framework.

In Sendai where our fantastic host @junotk.bsky.social opens up the meeting of the Japanese Phil of Science Association (ita founding members include physicist Yukawa, I am told) and to these days includes lots of logicians and scientists alike. Excellent opening talk by @terumiyake.bsky.social

Packed day at the Japanese Phil Scie Association with brilliant talks by @junotk.bsky.social on rethinking the ontology associated with statistical models and Hanti Lin on realism and machine learning. Huge thanks to @junotk.bsky.social for stellar organisation and unrivalled hospitality. 💫

It was such a great honor to host Prof. Michela Massimi’s @michelamassimi.bsky.social special lecture at the Japanese Philosophy of Science Association. Her talk was truly inspiring for thinking about a more human-centered form of science—something much needed today.

This perspective leads to rich and intriguing implications—for example, the importance of diversity in science, and Kuhnian paradigm shifts as phase transitions in Bayesian updating with singular models.
I really enjoyed working on this project with such an inspiring team of scientists! (3/n, n=3)

The central idea is that the scientific community can be viewed as a Metropolis–Hastings algorithm that approximates the posterior probability. (2/n)

New paper out in Royal Society Open Science!
In this paper, we propose a novel Bayesian framework to model scientific practice as a whole, based on Taniguchi's theory of Collective Predictive Coding. (1/n)

Collective predictive coding as model of science: formalizing scientific activities towards generative science | Royal Society Open Science

This article proposes a new conceptual framework called collective predictive coding as a model of science (CPC-MS) to formalize and understand scientific activities. Building on the idea of CPC originally developed to explain symbol emergence, CPC-MS ...

New preprint out! We use string diagrams to quantitatively model process causality (à la Salmon) and tackle issues like the Principle of Common Cause, explanatory irrelevance, and more—turns out process causation might be cooler than you thought.
