• Authors: Jonte R. Hance and Sabine Hossenfelder
• Abstract summary: Daley et al claim that some superdeterministic models are disfavoured against standard quantum mechanics. We argue that overfitting, while better as a measure of finetuning than other measures given in the literature, does not necessarily indicate a model is universally bad.

• Abstract: In a recent paper (Phys. Rev. A 105, 042220 (2022)), Daley et al claim that some superdeterministic models are disfavoured against standard quantum mechanics, because such models overfit the statistics of a Bell-type experiment which the authors conducted. We add to the discussion by providing additional context about how few superdeterministic models fall into the category they analyse, and by emphasising that overfitting, while better as a measure of finetuning than other measures given in the literature, does not necessarily indicate a model is universally bad.

• A view on model misspecification in uncertainty quantification [17.17262672213263]
  Estimating uncertainty of machine learning models is essential to assess the quality of the predictions that these models provide. Model misspecification always exists as models are mere simplifications or approximations to reality. This paper argues that model misspecification should receive more attention, by providing thought experiments and contextualizing these with relevant literature.

• Experimentally adjudicating between different causal accounts of Bell inequality violations via statistical model selection [0.0]
  Bell inequalities follow from a set of seemingly natural assumptions about how to provide a causal model of a Bell experiment. Two types of causal models that modify some of these assumptions have been proposed. We seek to adjudicate between these alternatives based on their predictive power.

We provide tractable algorithms to compute the range of attainable group-level predictive disparities. We extend our framework to address the empirically relevant challenge of selectively labelled data.

  This paper addresses whether an is-a relationship exists between words (x, y) with the help of large textual corpora. Recent studies suggest that pattern-based ones are superior, if large-scale Hearst pairs are extracted and fed, with the sparsity of unseen (x, y) pairs relieved. For the first time, this paper quantifies the non-negligible existence of those specific cases. We also demonstrate that distributional methods are ideal to make up for pattern-based ones in such cases.
