[DeepGOF] Where Does a Logistic Risk Model Fail? An Audited Neural Goodness-of-Fit Test for Model Development and External Validation

Read the original on arXiv Statistics ML →

DeepGOF-1 is a neural goodness‑of‑fit test for logistic regression that maps residuals over covariate ranks, scores them with a frozen convolutional network, and calibrates the score via parametric bootstrap. It achieves first‑order valid level, offers explicit local power, and outperforms traditional chi‑square and projection tests in simulations and real data, revealing missed interactions and guiding model repairs. In the SUPPORT study, it identified a U‑shaped risk pattern for blood pressure and respiratory rate that standard calibration curves obscured, and it ran in 13 seconds versus hours for competing methods.

DeepGOF-1: A Pretrained Convolutional Goodness-of-Fit Test for Logistic Regression with a Computable Consistency Certificate

DeepGOF-1 introduces a pretrained convolutional network as a goodness‑of‑fit test for logistic regression, where the network reads a grid of standardized residuals as an image and outputs a test statistic. The test is fully calibrated via the analyst’s own bootstrap, ensuring the nominal level is maintained regardless of the network’s training. The authors prove exactness under pivotality, asymptotic exactness without it, and provide a computable consistency certificate from the frozen weights, demonstrating superior stability and power across multiple benchmarks and sample sizes.

The Loss or the Architecture? What Matters in Survival Analysis with Competing Risks

The paper investigates whether the choice of loss function or network architecture is more critical for survival analysis with competing risks. By independently varying three loss functions (two strictly proper) and four backbone architectures across 20 tabular and 3 pathology‑image datasets, the authors find that modelling cumulative incidence directly with censoring weighting consistently outperforms other losses, while the backbone must match the data modality. Proper scoring rules reveal that the loss dominates performance on competing‑risk data, whereas the architecture matters more on single‑event data, and the two factors compound rather than substitute.

Differentiable latent structure discovery for interpretable forecasting in clinical time series

arXiv:2604. 27967v2 Announce Type: replace Abstract: Background: We introduce StructGP, a continuous-time multi-task Gaussian process that couples process convolutions with differentiable structure learning to uncover a sparse, ordered directed acyclic graph (DAG) of inter-variable dependencies while preserving principled uncertainty.

[EDGE] A grouped calibration test for logistic regression that tolerates a few corrupted records

The paper introduces EDGE, a grouped calibration test for logistic regression that remains robust when a few records are corrupted. EDGE projects grouped residuals onto a small basis of calibration shapes, keeping degrees of freedom independent of group count, which allows fine‑grained power or coarse protection against outliers. In simulations and external validation, EDGE matched or exceeded the power of existing tests while maintaining false‑alarm rates below 10% even with corrupted data.
