Task-Preserving Multilingual Instruction Tuning for Open-Ended QA in WMT 2026 MIST

This paper describes our submission to the WMT 2026 Multilingual Instruction Shared Task. We adapt Qwen3-8B with LoRA using organiser-provided data, EuroAlpaca, a multilingual instruction dataset created through task-preserving localisation, and CrossEuroAlpaca, a cross-lingual augmentation that assigns different sourc...

Federated Multilingual Speech-LLMs: Architecture and Aggregation Strategy Benchmarking

A comprehensive benchmark of Federated Learning for multilingual Automatic Speech Recognition (ASR) for multilingual Speech-LLM architectures, evaluating four Speech-LLM architectures on the Multilingual LibriSpeech dataset shows that optimized learning rates are critical for performance.

Component-Aware Differential Privacy for Federated Multilingual Speech-LLMs

This work empirically diagnose the root cause across six per-layer methods and three speech-LLM architectures and proposes a two-pool allocation that normalises encoder and LLM parameters into independent pools, and shows that joint $\ell_2$ sensitivity and the original $(\varepsilon,\delta)$-DP guarantee are unchanged...

EuroAlpaca: Task-Preserving Localisation of Instruction Data for European Languages

EuroAlpaca is introduced, a task-preserving localisation pipeline and near-parallel resource covering 50 European languages and regional varieties, together with European-IFEval, a multilingual benchmark for verifiable instruction following, showing that preserving task semantics is essential for multilingual instructi...
