RedunCut: Cost-Effective Live Video Analytics

Published:Dec 30, 2025 18:01
1 min read
ArXiv

Analysis

This paper addresses the high computational cost of live video analytics (LVA) by introducing RedunCut, a system that dynamically selects model sizes to reduce compute cost. The key innovation lies in a measurement-driven planner for efficient sampling and a data-driven performance model for accurate prediction, leading to significant cost reduction while maintaining accuracy across diverse video types and tasks. The paper's contribution is particularly relevant given the increasing reliance on LVA and the need for efficient resource utilization.
Reference

“RedunCut reduces compute cost by 14-62% at fixed accuracy and remains robust to limited historical data and to drift.”

FASER for Compressed Higgsinos

ArXiv

Analysis

This paper explores the potential of the FASER experiment to detect compressed Higgsinos, a specific type of supersymmetric particle predicted by the MSSM. The focus is on scenarios where the mass difference between the neutralino and the lightest neutralino is very small, making them difficult to detect with standard LHC detectors. The paper argues that FASER, a far-forward detector at the LHC, can provide complementary coverage to existing search strategies, particularly in a region of parameter space that is otherwise challenging to probe.

Key Takeaways

Reference

“FASER 2 could cover the neutral Higgsino mass up to about 130 GeV with mass splitting between 4 to 30 MeV.”

Renormalization Group Invariants in Supersymmetric Theories

Published:Dec 29, 2025 17:43
1 min read
ArXiv

Analysis

This paper summarizes and reviews recent advancements in understanding the renormalization of supersymmetric theories. The key contribution is the identification and construction of renormalization group invariants, quantities that remain unchanged under quantum corrections. This is significant because it provides exact results and simplifies calculations in these complex theories. The paper explores these invariants in various supersymmetric models, including SQED+SQCD, the Minimal Supersymmetric Standard Model (MSSM), and a 6D higher derivative gauge theory. The verification through explicit three-loop calculations and the discussion of scheme-dependence further strengthen the paper's impact.
Reference

“The paper discusses how to construct expressions that do not receive quantum corrections in all orders for certain ${\cal N}=1$ supersymmetric theories, such as the renormalization group invariant combination of two gauge couplings in ${\cal N}=1$ SQED+SQCD.”

Physical Constraints on Black Hole Chaos

Published:Dec 28, 2025 08:27
1 min read
ArXiv

Analysis

This paper addresses inconsistencies in the study of chaotic motion near black holes, specifically concerning violations of the Maldacena-Shenker-Stanford (MSS) chaos-bound. It highlights the importance of correctly accounting for the angular momentum of test particles, which is often treated incorrectly. The authors develop a constrained framework to address this, finding that previously reported violations disappear under a consistent treatment. They then identify genuine violations in geometries with higher-order curvature terms, providing a method to distinguish between apparent and physical chaos-bound violations.
