The paper introduces a physics-informed self‑supervised learning framework that jointly calibrates wire gains and reconstructs interaction positions in Multi‑Wire Parallel Plate Avalanche Counters (MWPPACs) without labelled data or dedicated calibration runs. By treating calibration as a latent optimization problem, the method simultaneously estimates global wire gains and event‑wise positions using only detector geometry and charge‑energy consistency constraints. A detector‑independent neural network learns sub‑wire position reconstruction from local charge distributions, enabling continuous self‑calibration and improved spatial homogeneity and resolution, as demonstrated on the VAMOS++ spectrometer’s entrance MWPPACs.

The paper introduces SMART, a lightweight recalibration technique that adjusts logits based on the margin between the top two logits, called the logit gap. It uses a soft-binned Expected Calibration Error objective to balance bias and variance, enabling stable updates even with limited calibration data. Experiments across various datasets and architectures show SMART achieves state‑of‑the‑art calibration with fewer parameters than existing methods.

Zero-Shot Self-Supervised Learning (ZS-SSL) has emerged as a promising paradigm for accelerated Magnetic Resonance Imaging (MRI) reconstruction, eliminating the reliance on fully-sampled external datasets. However, learning solely from a single under-sampled scan suffers from supervision scarcity and optimization instability, often leading to overfitting or artifacts.
