This paper discusses an alternative to conditioning that may be used when the prob-<lb>ability distribution is not fully specified. It does not require any assumptions (such<lb>as CAR: coarsening at random) on the unknown distribution. The well-known Monty<lb>Hall problem is the simplest scenario where neither naive conditioning nor the CAR<lb>assumption… (More)

Decision makers must often base their decisions on incomplete (coarse) data. Recent research has shown that in a wide variety of coarse data problems, minimax optimal strategies can be recognized using a simple probabilistic condition. This paper develops a computational method to find such strategies in special cases, and shows what difficulties may arise… (More)

Methods for combining predictions from different models in a supervised learning setting must somehow estimate/predict the quality of a model’s predictions at unknown future inputs. Many of these methods (often implicitly) make the assumption that the test inputs are identical to the training inputs, which is seldom reasonable. By failing to take into… (More)

Despite their popularity, many questions about the algebraic constraints imposed by linear structural equation models remain open problems. For causal discovery, two of these problems are especially important: the enumeration of the constraints imposed by a model, and deciding whether two graphs define the same statistical model. We show how the half-trek… (More)

An important goal in both transfer learning and causal inference is to make accurate predictions when the distribution of the test set and the training set(s) differ. Such a distribution shift may happen as a result of an external intervention on the data generating process, causing certain aspects of the distribution to change, and others to remain… (More)
