A Query Is Not a Commitment: Learning to Correct Expert Answers in Online Deferral

Yannis Montreuil, Axel Carlier, Lai Xing Ng +1

An inaccurate expert can still provide useful information after correction. We study online learning to defer in which the learner chooses an expert and fixes a correction function…

Toward On-Chip Training of Spiking Neural Networks for Dense Event-Based Vision

Maxime Vaillant, Axel Carlier, Lai Xing Ng +2

Event cameras provide low-latency, asynchronous visual sensing for resource-constrained robotics. Spiking neural networks (SNNs) process event streams naturally, but training deep…

Beyond Augmented-Action Surrogates for Multi-Expert Learning-to-Defer

Yannis Montreuil, Axel Carlier, Lai Xing Ng +1

A learning-to-defer (L2D) system decides, for each input, whether to predict on its own or to hand it to one of several available experts. The very well established recipe trains c…

Online Learning-to-Defer with Varying Experts

Dang Hoang Duy, Yannis Montreuil, Maxime Meyer +3

Learning-to-Defer (L2D) methods route each query either to a predictive model or to external experts. Real-world deployments require handling streaming data, changing expert availa…

SpikeCLR: Contrastive Self-Supervised Learning for Few-Shot Event-Based Vision using Spiking Neural Networks

Maxime Vaillant, Axel Carlier, Lai Xing Ng +2

Event-based vision sensors provide significant advantages for high-speed perception, including microsecond temporal resolution, high dynamic range, and low power consumption. When…

Consistent Learning-to-Defer with Expert-Conditional Advice

Yannis Montreuil, Leïna Montreuil, Axel Carlier +2

We introduce learning-to-defer with advice, a new setting in which a system learns both which expert should handle an input and which information that expert should receive. The po…

Learning-to-Defer in Non-Stationary Time Series via Switching State-Space Models

Yannis Montreuil, Letian Yu, Axel Carlier +2

Learning-to-defer (L2D) lets a predictor decide, at each round, whether to issue its own forecast or pay for an expert's. In non-stationary time series this decision must keep adap…

Adversarial Robustness in One-Stage Learning-to-Defer

Yannis Montreuil, Letian Yu, Axel Carlier +2

Learning-to-Defer (L2D) enables hybrid decision-making by routing inputs either to a predictor or to external experts. While promising, L2D is highly vulnerable to adversarial pert…

One-Stage Top- Learning-to-Defer: Score-Based Surrogates with Theoretical Guarantees

Yannis Montreuil, Axel Carlier, Lai Xing Ng +1

We introduce the first one-stage Top- Learning-to-Defer framework, which unifies prediction and deferral by learning a shared score-based model that selects the most cost-ef…

Why Ask One When You Can Ask ? Learning-to-Defer to the Top- Experts

Yannis Montreuil, Axel Carlier, Lai Xing Ng +1

Existing Learning-to-Defer (L2D) frameworks are limited to single-expert deferral, forcing each query to rely on only one expert and preventing the use of collective expertise. We…

Adversarial Robustness in Two-Stage Learning-to-Defer: Algorithms and Guarantees

Yannis Montreuil, Axel Carlier, Lai Xing Ng +1

Two-stage Learning-to-Defer (L2D) enables optimal task delegation by assigning each input to either a fixed main model or one of several offline experts, supporting reliable decisi…

Optimal Query Allocation in Extractive QA with LLMs: A Learning-to-Defer Framework with Theoretical Guarantees

Yannis Montreuil, Shu Heng Yeo, Axel Carlier +2

Large Language Models excel in generative tasks but exhibit inefficiencies in structured text selection, particularly in extractive question answering. This challenge is magnified…

A Two-Stage Learning-to-Defer Approach for Multi-Task Learning

Yannis Montreuil, Shu Heng Yeo, Axel Carlier +2

The Two-Stage Learning-to-Defer (L2D) framework has been extensively studied for classification and, more recently, regression tasks. However, many real-world applications require…

Quality Control in Crowdsourced Object Segmentation

Ferran Cabezas, Axel Carlier, Amaia Salvador +2

This paper explores processing techniques to deal with noisy data in crowdsourced object segmentation tasks. We use the data collected with "Click'n'Cut", an online interactive seg…
