Improvements in Perpendicular Reverse Parking by Directing Drivers' Preliminary Behavior

Y Ohama, K Tanaka, H Yasuda, K Obata… - IEEE …, 2021 - ieeexplore.ieee.org
Driving vehicles requires mastery of a multitude of tasks. Among these, parking is one task
that most drivers feel they are not as skilled as they would like to be. In this paper, we focus on …

Toward a practical wall see-through system for drivers: How simple can it be?

H Yasuda, Y Ohama - 2012 IEEE International Symposium on …, 2012 - ieeexplore.ieee.org
This study specifically examines wall see-through visualization for drivers at blind corners to
prevent crossing collisions. We believe that realizing the desired effect with the simplest …

A parallel forward-backward propagation learning scheme for auto-encoders

Y Ohama, T Yoshimura - … , ICONIP 2017, Guangzhou, China, November 14 …, 2017 - Springer
Auto-encoders constitute one popular deep learning architecture for feature extraction. Since
an auto-encoder has at least one bottle neck layer for feature representation and at least …

A simplified forward-propagation learning rule applied to adaptive closed-loop control

Y Ohama, N Fukumura, Y Uno - International Conference on Artificial …, 2005 - Springer
In terms of computational neuroscience, several theoretical learning schemes have been
proposed to acquire suitable motor controllers in the human brain. The controllers have been …

It has been suggested that inverse models serve feedforward controllers in the human brain.
We have proposed a novel learning scheme to acquire a neural inverse model of a …

MARPF: Multi-Agent and Multi-Rack Path Finding

H Makino, Y Ohama, S Ito - arXiv preprint arXiv:2403.12376, 2024 - arxiv.org
In environments where many automated guided vehicles (AGVs) operate, planning efficient,
collision-free paths is essential. Related research has mainly focused on environments with …

Learning of real robot's inverse dynamics by a forward‐propagation learning rule

H Mori, Y Ohama, N Fukumura… - Electrical Engineering in …, 2007 - Wiley Online Library
A forward‐propagation learning rule (FPL) has been proposed for a neural network (NN) to
learn an inverse model of a controlled object. A feature of FPL is that the trajectory error …
