Learning and Strongly Truthful Multi-Task Peer Prediction: A Variational Approach [article]

Grant Schoenebeck, Fang-Yi Yu
2020 arXiv   pre-print
We design a family of mechanisms with a scoring function that maps a pair of reports to a score.  ...  Peer prediction mechanisms incentivize agents to truthfully report their signals even in the absence of verification by comparing agents' reports with those of their peers.  ...  inequality: Theorem A.1 (Young-Fenchel inequality).  ...

New Optimisation Methods for Machine Learning [article]

Aaron Defazio
2016 arXiv   pre-print
Specifically, for the combined approach, we introduce a new method for encouraging graph structures with the "scale-free" property.  ...  For the structure learning problem, we establish SHORTCUT, a O(n^2.5) expected time approximate structure learning method for Gaussian graphical models.  ...  Fenchel-Young Inequality Given a dual point u and a primal point x, it holds that: f (x) + f * (u) ≥ x, u .  ...

Uncertainty quantification in unfolding elementary particle spectra at the Large Hadron Collider

Mikael Johan Kuusela
We demonstrate that basing the uncertainties on the variability of the bias-corrected point estimator provides significantly improved coverage with only a modest increase in the length of the confidence  ...  The first approach applies to situations where the unfolded spectrum is expected to be a smooth function and consists in using an iterative bias-correction technique for debiasing the unfolded point estimator  ...  The decision-theoretic justification for the MAP estimator is that it arises as the limit of decisions minimizing the posterior expected loss for the 0-1 loss function where l (β; y) = log p(y|β) is the  ...
