Co-occurrence-Aware Quadratic Assignment for Local Feature Matching in Simultaneous Localization and Mapping
Yutaka Yamada, Yohei Hamakawa, Yutaro Ishigaki +2
Local feature matching, which associates keypoints in two images as keypoint pairs, is fundamental to Visual Simultaneous Localization and Mapping (Visual SLAM). Nearest Neighbor (…
Real-Time Black-Box Optimization for Dynamic Discrete Environments Using Embedded Ising Machines
Tomoya Kashimata, Yohei Hamakawa, Masaya Yamasaki +1
Many real-time systems require the optimization of discrete variables. Black-box optimization (BBO) algorithms and multi-armed bandit (MAB) algorithms perform optimization by repea…
Machine Learning-assisted High-speed Combinatorial Optimization with Ising Machines for Dynamically Changing Problems
Yohei Hamakawa, Tomoya Kashimata, Masaya Yamasaki +1
Quantum or quantum-inspired Ising machines have recently shown promise in solving combinatorial optimization problems in a short time. Real-world applications, such as time divisio…
Enhancing In-vehicle Multiple Object Tracking Systems with Embeddable Ising Machines
Kosuke Tatsumura, Yohei Hamakawa, Masaya Yamasaki +2
A cognitive function of tracking multiple objects, needed in autonomous mobile vehicles, comprises object detection and their temporal association. While great progress owing to ma…
Efficient and Scalable Architecture for Multiple-chip Implementation of Simulated Bifurcation Machines
Tomoya Kashimata, Masaya Yamasaki, Ryo Hidaka +1
Ising machines are specialized computers for finding the lowest energy states of Ising spin models, onto which many practical combinatorial optimization problems can be mapped. Sim…
Real-time Trading System based on Selections of Potentially Profitable, Uncorrelated, and Balanced Stocks by NP-hard Combinatorial Optimization
Kosuke Tatsumura, Ryo Hidaka, Jun Nakayama +2
Financial portfolio construction problems are often formulated as quadratic and discrete (combinatorial) optimization that belong to the nondeterministic polynomial time (NP)-hard…
