Human-error-potential Estimation based on Wearable Biometric Sensors
Hiroki Ohashi, Hiroto Nagayoshi
This study tackles on a new problem of estimating human-error potential on a shop floor on the basis of wearable sensors. Unlike existing studies that utilize biometric sensing tec…
Sensor-Augmented Egocentric-Video Captioning with Dynamic Modal Attention
Katsuyuki Nakamura, Hiroki Ohashi, Mitsuhiro Okada
Automatically describing video, or video captioning, has been widely studied in the multimedia field. This paper proposes a new task of sensor-augmented egocentric-video captioning…
Class-Wise Difficulty-Balanced Loss for Solving Class-Imbalance
Saptarshi Sinha, Hiroki Ohashi, Katsuyuki Nakamura
Class-imbalance is one of the major challenges in real world datasets, where a few classes (called majority classes) constitute much more data samples than the rest (called minorit…
Attributes' Importance for Zero-Shot Pose-Classification Based on Wearable Sensors
Hiroki Ohashi, Mohammad Al-Naser, Sheraz Ahmed +3
This paper presents a simple yet effective method for improving the performance of zero-shot learning (ZSL). ZSL classifies instances of unseen classes, from which no training data…
