Catch, Adapt, and Operate: Monitoring ML Models Under Drift

🗓️ April 2026

📍 Rio de Janeiro, Brazil

About

This workshop addresses methods for ensuring the reliability of machine learning systems under distributional drift. Such drift may occur as temporal, label/concept, domain, or representation shift, each presenting unique challenges for monitoring and adaptation. We organize the program into three complementary themes:

Sensing the Drift: Developing tools to detect when models encounter distributional change, using statistical tests, kernel methods, uncertainty estimation, and representation-based monitoring. This theme focuses on identifying drift early and minimizing false alarms in real-world pipelines.
Responding to Drift: Designing strategies that adapt models once drift is detected, including test-time adaptation, continual and online learning, regularization, and selective prediction. The focus is on maintaining accuracy and stability while avoiding catastrophic forgetting.
Operating at Scale: Extending monitoring and adaptation to large-scale production environments, where heterogeneous data streams, governance requirements, and real-time costs amplify the challenge. This theme emphasizes system design, infrastructure, bench- marks, and protocols for reliable deployment at scale.

Together, these themes establish a unified research agenda for developing robust and trustworthy

ML systems in dynamic, non-stationary environments.

Call for Papers

We invite contributions spanning monitoring, adaptation, fairness, and governance of ML systems under distributional drift, including (but not limited to):

Drift detection and characterization: Statistical tests, kernel methods, density-ratio estimation, causal or graph-based change detection, sequential monitoring, and early-warning systems for drift identification.
Representation and uncertainty: Calibration, uncertainty estimation, explainability, and representation-based monitoring for identifying concept, covariate, or representation drift.
Adaptation and recovery: Test-time adaptation, online learning, continual learning, domain generalization, and meta-learning approaches for handling evolving data distributions.
Fairness and bias under drift: Methods for maintaining fairness, subgroup robustness, and demographic parity as data or population shifts occur; detection and mitigation of emerging biases during deployment.
Governance and auditing: Frameworks for model monitoring under regulatory and compliance constraints; accountability, audit trails, and explainable intervention mechanisms in high-stakes domains.
Reliability at scale: Systems and infrastructure for large-scale monitoring, data logging, alerting, and automated response in production pipelines.

Submission Instructions

Submissions must be made through OpenReview and formatted using the ICLR conference proceedings style.

We invite submissions to two tracks:

Main Track

Papers submitted to the main track may be up to 8 pages, excluding references.

Tiny Papers Track

Tiny papers are intended for concise contributions and must be no longer than 5 pages in total, including references.

All submissions will undergo a double-blind, non-archival review process.

All accepted papers will be presented in an extended poster session at the workshop. In addition, a small number of papers will be selected for spotlight oral presentations.

Special Track: Lessons from Failures 📝

Beyond the main track, we will host a dedicated track on Lessons from Failures: Understanding What Did Not Work and Why.
Submissions to this track are limited to a maximum of 4 pages, excluding references, and should follow the ICLR formatting guidelines.

This track welcomes submissions that report:

Methods that fell short of expectations
Failed or inconclusive experiments
Unexpected challenges or negative results

By encouraging openness about what did not work, this track aims to reduce duplicated effort, strengthen scientific rigor, and accelerate progress across the community.

Best Paper Award 🏆

We are pleased to introduce a Best Paper Award and 3 Best poster awards. to recognize exceptional submissions. Award recipients will receive:

A certificate of recognition
A monetary prize, generously sponsored by RBC Borealis.

Selections will be made based on recommendations from the program committee.

Travel Grants 🧳

To promote inclusivity and broaden participation, we are offering a number of travel grants to support attendees from diverse backgrounds. This initiative is made possible through the generous support of RBC Borealis and aims to foster richer and more inclusive discussions at the workshop.
