Knowing When Not to Predict: Self Supervised Learning and Abstention for Safer DR Screening

Muskaan Chopra, Lorenz Sparrenberg, Jan H. Terheyden +1

Self-supervised learning (SSL) is now a standard way to pretrain medical image models, but performance is still mostly judged by downstream accuracy. For safety-critical screening…

History Rhymes: Macro-Contextual Retrieval for Robust Financial Forecasting

Sarthak Khanna, Armin Berger, Muskaan Chopra +2

Financial markets are inherently non-stationary: structural breaks and macroeconomic regime shifts often cause forecasting models to fail when deployed out of distribution (OOD). C…

How Small Can You Go? Compact Language Models for On-Device Critical Error Detection in Machine Translation

Muskaan Chopra, Lorenz Sparrenberg, Sarthak Khanna +1

Large Language Models (LLMs) excel at evaluating machine translation (MT), but their scale and cost hinder deployment on edge devices and in privacy-sensitive workflows. We ask: ho…

SynCED-EnDe 2025: A Synthetic and Curated English - German Dataset for Critical Error Detection in Machine Translation

Muskaan Chopra, Lorenz Sparrenberg, Rafet Sifa

Critical Error Detection (CED) in machine translation aims to determine whether a translation is safe to use or contains unacceptable deviations in meaning. While the WMT21 English…
