Beyond Parallel Sampling: Diverse Query Initialization for Agentic Search

Sidhaarth Murali, João Coelho, Jingjie Ning +3

Test-time scaling for agentic search typically increases depth (i.e., more turns and tokens per trajectory) or breadth (i.e., more parallel rollouts). Here we focus on breadth scal…

Effective Reinforcement Learning for Agentic Search by Recycling Zero-Variance Queries During Training

João Coelho, João Magalhães, Bruno Martins +1

The use of GRPO-style algorithms has become the standard strategy for training LLM search agents under outcome-only rewards. With these algorithms, a query contributes to parameter…

ALBA: A European Portuguese Benchmark for Evaluating Language and Linguistic Dimensions in Generative LLMs

Inês Vieira, Inês Calvo, Iago Paulo +6

As Large Language Models (LLMs) expand across multilingual domains, evaluating their performance in under-represented languages becomes increasingly important. European Portuguese…

AMALIA Technical Report: A Fully Open Source Large Language Model for European Portuguese

Afonso Simplício, Gonçalo Vinagre, Miguel Moura Ramos +19

Despite rapid progress in open large language models (LLMs), European Portuguese (pt-PT) remains underrepresented in both training data and native evaluation, with machine-translat…

Agentic Search in the Wild: Intents and Trajectory Dynamics from 14M+ Real Search Requests

Jingjie Ning, João Coelho, Yibo Kong +5

LLM-powered search agents are increasingly being used for multi-step information seeking tasks, yet the IR community lacks empirical understanding of how agentic search sessions un…

An Efficient and Effective Encoder Model for Vision and Language Tasks in the Remote Sensing Domain

João Daniel Silva, Joao Magalhaes, Devis Tuia +1

The remote sensing community has recently seen the emergence of methods based on Large Vision and Language Models (LVLMs) that can address multiple tasks at the intersection of com…
