October 25-27, 2013
The Case Studies of Causal Discovery with Model Search Workshop is focused on applications of causal model search to science. It will include sessions on model search in Genetics, Biology, fMRI, Educational Research, Economics, and other disciplines.
Dates: October 25-27, 2013 (Friday-Sunday)
Location: Carnegie Mellon University, Pittsburgh, PA
The Friday sessions will take place in Rangos Hall (2nd floor, University Center)
The Saturday and Sunday sessions will take place in Baker Hall A53
Computer scientists, statisticians, and philosophers have created a precise mathematical framework for representing causal systems called "Graphical Causal Models." This framework has supported the rigorous description of causal model spaces and the notion of empirical indistinguishability/equivalence within such spaces, which has in turn enabled computer scientists to develop asymptotically reliable model search algorithms for efficiently searching these spaces. The conditions under which these methods are practically useful in applied science is the topic of this workshop. The workshop will bring together scholars from genetics, biology, economics, fMRI-based cognitive neuroscience, climate research, education research, and several other disciplines, all of whom have successfully applied computerized search for causal models toward a scientifically challenging problem. The goals for the workshop are to: (1) to identify strategies for applying causal model search to diverse domain-specific scientific questions; (2) to identify and discuss methodological challenges that arise when applying causal model search to real-world scientific problems; and (3) to take concrete steps toward creating an interdisciplinary community of researchers interested in applied causal model search. We welcome junior scholars and graduate students, and we will host a free introductory tutorial on model search the first morning of the workshop.

Workshop on the Logic of Simplicity
June 7-9 2013
Rationale: Ockham's razor is the characteristic bias toward simple hypotheses that has characterized scientific inquiry since Copernicus. But what is it, exactly? This workshop aims to revisit that question from a fresh logical perspective. Potential candidates for the simplicity order include dimensionality, Kolmogorov complexity, and VC dimension. Candidates for Ockham's razor, itself, include logical theories for revising belief in light of such an order in the deterministic case and a host of model selection methods on the side of statistics and machine learning. This interdisciplinary workshop will begin to explore a number of new and interesting logical questions at the interface of logic and scientific method. Which orders are simplicity orders? Is simplicity relative to questions or subject to other framing effects? How should a simplicity order be modified in light of new information? What may one believe in light of a simplicity order and given information? What should one do if the simplicity order branches? Are the essential features of a simplicity order preserved by the associated belief revision rule? Are standard belief revision principles descriptively plausible in scientific applications? Is simplicity absolute or relative to framing effects? Is there any normative reason to revise according to simplicity rather than some other principle? Addressing these fundamental questions promises both to sharpen our conception of scientific method and to broaden our ideas about the logic of belief revision.

Workshop on the Foundations of Ockham's Razor
June 22-24, 2012,
Scientific theory choice is guided by judgments of simplicity, a bias frequently referred to as "Ockham's Razor". But what is simplicity and how, if at all, does it help science find the truth? Should we view simple theories as means for obtaining accurate predictions, as classical statistics and machine learning urge? Or should we believe the theories themselves, as Bayesian methods seem to justify? The aim of this workshop is to re-examine the foundations of Ockham's razor, with a firm focus on the connections, if any, between simplicity and truth.

Commemorative Collection for Horacio Arlo-Costa. To honor Horacio Arlo-Costa's memory and influence on all of us in the community, Jeffrey Helzner, Vincent F. Hendricks, Paul Pedersen and Gregory Wheeler will be editing a book with essays on his philosophy, his intellectual biography, his official obituary, words of remembrance from his friends and colleagues, his unpublished manuscripts and notes, and other relevant communications from or about Horacio. If you have words of remembrance, please feel welcome to post them at Choice and Inference under the entry In Memory of Horacio Arlo-Costa, as we will, with your permission, use your words of remembrance for the volume. Please send all other material (correspondences, notes, etc.) to any one of the editors:
In Memoriam: Horacio Arlo-Costa (1956-2011). We deeply regret the sudden passing of CFE Associate Director Horacio Arlo-Costa. The Center's ambitious schedule of six events in its first year of operation was due in large part to Horacio's indefatigable dedication. His stature in formal epistemology is familiar. His tireless enthusiasm, his widespread connections in the field and his renowned, encyclopedic knowledge of the literature and the contributions of others made him an indespensable partner in the wild adventure that constituted the Center's crucial first year of operation. He will be missed sorely. In spite of his many other duties and concerns, Horacio reveled in the CFE's rapid expansion . To vindicate his commitment, the CFE will redouble its efforts to facilitate the cause of formal philosophy in the coming years.
The Commemorative Colloquium for CFE Associate Director Horacio Arlo-Costa was held on November 19-20, 2011. Thanks to all the speakers for making the Colloquium a great success! Here is the schedule of talks.

The Episteme annual conference on Social Epistemology was held at the CFE on June 24-26, 2011 in coordination with Alvin Goldmanand Christian List. Here is the revised schedule and a link to arrangements.
There was a joint CSLI-CFE-San Francisco State workshop on Logic and Formal Epistemology at CSLI, Stanford on May 14 and 15, 2011, organized by Johan van Benthem, Bas van Fraassen, and Kevin van Kelly. The topics will be learning in epistemic logic and a re-examination of norms in empirical reasoning. Local organizers Peter Hawke, Wes Holliday, Tomohiro Hoshi, and Thomas Icard at Stanford did a fantastic job and the workshop was supported mainly by the generosity of Patrick Suppes and the Department of Philosophy at Stanford. We hope this is the beginning of a long tradition.
On March 16, 12:00-4:00 there was a symposium on uncertain acceptance involving Hannes Leitgeb, Horacio Arlo-Costa, Kevin Kelly, Paul Pedersen, and Hanti Lin in DH. The symposium compared notes on three new but distinct approaches to the subject.
The workshop on Experience,
Heuristics, and Choice: Prospects for Bounded Rationality on
Dec 1, 2010 was a great
success. Thanks to all who participated.
