Transfer Learning for Classification under Decision Rule Drift with Application to Optimal Individualized Treatment Rule Estimation
In this paper, we extend the transfer learning classification framework from regression function-based methods to decision rules. We propose a novel methodology for modeling posterior drift through Bayes decision rules. By exploiting the geometric transformation of the Bayes decision boundary, our method reformulates the problem as a low-dimensional empirical risk minimization problem. Under mild regularity conditions, we establish the consistency of our estimators and derive the risk bounds. M…

Theoretically, a specific federal court could say the feds can’t kill me, or you, or anyone, where we stand for saying “trump is a weak child.”
And such restriction on federal use of force might only apply within that federal circuit.
We cross a boundary, an injunction against our summary execution may not hold.
That’s the illogical but real conclusion of scotus’ bad decision this week as I understand it.
Can the dead file suit against their already-carried out ex…

Inverse Chance Constrained Optimal Power Flow
The chance constrained optimal power flow (CC-OPF) essentially finds the low-cost generation dispatch scheme ensuring operational constraints are met with a specified probability, termed the security level. While the security level is a crucial input parameter, how it shapes the CC-OPF feasibility boundary has not been revealed. Changing the security level from a parameter to a decision variable, this letter proposes the inverse CC-OPF that seeks the highest feasible security level supported by…

Rule-based Key-Point Extraction for MR-Guided Biomechanical Digital Twins of the Spine
Digital twins offer a powerful framework for subject-specific simulation and clinical decision support, yet their development often hinges on accurate, individualized anatomical modeling. In this work, we present a rule-based approach for subpixel-accurate key-point extraction from MRI, adapted from prior CT-based methods. Our approach incorporates robust image alignment and vertebra-specific orientation estimation to generate anatomically meaningful landmarks that serve as boundary conditions …

Performative Validity of Recourse Explanations
When applicants get rejected by an algorithmic decision system, recourse explanations provide actionable suggestions for how to change their input features to get a positive evaluation. A crucial yet overlooked phenomenon is that recourse explanations are performative: When many applicants act according to their recommendations, their collective behavior may change statistical regularities in the data and, once the model is refitted, also the decision boundary. Consequently, the recourse algori…

Good Morning #Canada
It's a holiday across most of our nation today, so why not take 14 minutes to find out why Alaska isn't part of Canada and discover why Lord Alverstone is the villain you've likely never heard of.
Lord Alverstone, whose full name was Richard Everard Webster, 1st Viscount Alverstone, played a key role in the Alaska Boundary Dispute of 1903. As the British representative on the arbitration tribunal, he ultimately sided with the United States, leading to a decision that favored the US claim over Canada's claims regarding the Alaska panhandle. At the time, the British government was trying to rebuild relationships with the U.S. and likely instructed Lord Alverstone to rule against Canadian border claims.

RPRA-ADD: Forgery Trace Enhancement-Driven Audio Deepfake Detection
Existing methods for deepfake audio detection have demonstrated some effectiveness. However, they still face challenges in generalizing to new forgery techniques and evolving attack patterns. This limitation mainly arises because the models rely heavily on the distribution of the training data and fail to learn a decision boundary that captures the essential characteristics of forgeries. Additionally, relying solely on a classification loss makes it difficult to capture the intrinsic difference…
