Vector Symbolic Policy Gradient

Ryozo Masukawa, Sanggeon Yun, SungHeon Jeong +6

We answer this question with Vector-Symbolic Policy Gradient (VSPG), a discrete-action actor that represents each action by a unit-norm hypervector and scores it by similarity to t…

Qubit-Efficient Quantum Search for Hyperdimensional Decomposition via Logarithmic Encoding

Sanggeon Yun, Hyunwoo Oh, Ryozo Masukawa +2

Hyperdimensional Computing (HDC) represents symbols using high-dimensional hypervectors of dimension . In hypervector decomposition, the objective is to recover constituent…

MissionHD: Hyperdimensional Refinement of Distribution-Deficient Reasoning Graphs for Video Anomaly Detection

Sanggeon Yun, Raheeb Hassan, Ryozo Masukawa +2

LLM-generated reasoning graphs, referred to as mission-specific graphs (MSGs), are increasingly used for video anomaly detection (VAD) and recognition (VAR). However, they are typi…

-Musketeers: Reinforcement Learning Shapes Collaboration Among Language Models

Ryozo Masukawa, Sanggeon Yun, Hyunwoo Oh +8

Recent progress in reinforcement learning with verifiable rewards (RLVR) shows that small, specialized language models (SLMs) can exhibit structured reasoning without relying on la…

HopFormer: Sparse Graph Transformers with Explicit Receptive Field Control

Sanggeon Yun, Raheeb Hassan, Ryozo Masukawa +2

Graph Transformers typically rely on explicit positional or structural encodings and dense global attention to incorporate graph topology. In this work, we show that neither is ess…
