Enhancing Graph Classification Robustness with Singular Pooling

NeurIPS 2025poster

Graph Neural Networks (GNNs) have achieved strong performance across a range of graph representation learning tasks, yet their adversarial robustness in graph classification remains underexplored compared to node classification. While most existing defenses focus on the message-passing component, th…

Pool Me Wisely: On the Effect of Pooling in Transformer-Based Models

NeurIPS 2025poster

Transformer models have become the dominant backbone for sequence modeling, leveraging self-attention to produce contextualized token representations. These are typically aggregated into fixed-size vectors via pooling operations for downstream tasks. While much of the literature has focused on atten…

Prompt Tuning Decision Transformers with Structured and Scalable Bandits

NeurIPS 2025poster

Prompt tuning has emerged as a key technique for adapting large pre-trained Decision Transformers (DTs) in offline Reinforcement Learning (RL), particularly in multi-task and few-shot settings. The Prompting Decision Transformer (PDT) enables task generalization via trajectory prompts sampled unifor…
