CAtNIPP: Context-aware attention-based network for informative path planning
Published in Proceedings of Machine Learning Research, 2024
This work is orally presented at the 6th Conference on Robot Learning (CoRL) 2024. Informative Path Planning (IPP) is a challenging problem that requires balancing exploration and exploitation under resource constraints. CAtNIPP introduces a fully reactive, deep reinforcement learning-based solution using self-attention to guide efficient path planning. By learning to form a global context and make adaptive local decisions, CAtNIPP outperforms traditional IPP methods in both performance and computation speed, with demonstrated results on real hardware.

Unleashing the Potential of Large Language Models for Knowledge Augmentation: A Practical Experiment on Incremental Sheet Forming
Published in Procedia Computer Science, 2024
This research is presented at the International Conference on Industry 4.0 and Smart Manufacturing (ISM) 2024. It explores how Large Language Models (LLMs) can be adapted to better understand and operate within the Incremental Sheet Forming (ISF) domain. By developing an automated pipeline for extracting and enriching ISF-specific knowledge, and fine-tuning models like Alpaca-33B, the study achieves a 10.4% improvement in domain knowledge acquisition over GPT-3.5. A new conversational prototype further boosts accuracy and relevance, paving the way for advanced ISF applications such as knowledge graphs and quality prediction.
