A tree-structured representation for book author and its recommendation using multilayer SOM

2015

This paper introduces a new framework for author recommending using Multi-Layer Self-Organizing Map (ML-SOM). Concretely, an author is modeled by a tree-structured representation, and an MLSOM-based system is used as an efficient solution to the …

Defect Prediction via LSTM Based on Sequence and Tree Structure

2020

With the ever-expanding spread of contemporary software, software defect prediction (SDP) is attracting more and more attention. However, sequential networks used in previous studies, weaken syntactic information and fail to capture longdistance dependencies. To solve …

CIF-PT: Bridging Speech and Text Representations for Spoken Language Understanding via Continuous Integrate-and-Fire Pre-Training

2023 · arXiv (Cornell University)

Speech or text representation generated by pre-trained models contains modal-specific information that could be combined for benefiting spoken language understanding (SLU) tasks. In this work, we propose a novel pre-training paradigm termed Continuous Integrate-and-Fire Pre-Training …

Process-Supervised Reinforcement Learning for Interactive Multimodal Tool-Use Agents

2025 · arXiv (Cornell University)

Effective interactive tool use requires agents to master Tool Integrated Reasoning (TIR): a complex process involving multi-turn planning and long-context dialogue management. To train agents for this dynamic process, particularly in multi-modal contexts, we introduce …
