Exploration behavior of group-in-a-box layouts

Autor: Yuki Ueno, Hiroaki Natsukawa, Nozomi Aoyama, Koji Koyamada

Publikováno v: Visual Informatics, Vol 3, Iss 1, Pp 38-47 (2019)

To improve visualization, it is necessary to optimize the design by analyzing the behavior of users as well as improving the evaluation index of the computational experiment and the task performance (e.g., the correct answer rate and completion time)

A visual analytics system to support the formation of a hypothesis from calcium wave data

Autor: Kozen Umezawa, Hiroaki Natsukawa, Yosuke Onoue, Koji Koyamada

Publikováno v: Visual Informatics, Vol 2, Iss 1, Pp 2-13 (2018)

In most species, calcium waves in the oocyte are considered common phenomena in the activation of eggs. However, the mechanism of calcium waves has not yet been clarified. By collaborating with biologists studying Caenorhabditis elegans (C. elegans),

An Interactive Approach for Hierarchical Parameter Optimization

Autor: Teppei TANAKA, Takayuki ITOH, Naohisa SAKAMOTO, Koji KOYAMADA

Publikováno v: Journal of Fluid Science and Technology, Vol 3, Iss 4, Pp 586-597 (2008)

We propose a novel interactive parameter optimization technique which asks users to determine whether further exploration is required by using a hierarchical visualization technique. Our technique generates a k-d tree and uses the coefficient of mult

Publikováno v: PLoS ONE, Vol 7, Iss 11, p e50218 (2012)

BACKGROUND: Activation of caspases is crucial for the execution of apoptosis. Although the caspase cascade associated with activation of the initiator caspase-8 (CASP8) has been investigated in molecular and biochemical detail, the dynamics of CASP8

A Visual Analytics Approach for Ecosystem Dynamics based on Empirical Dynamic Modeling

Autor: Hiroaki Natsukawa, Koji Koyamada, Ethan R. Deyle, Gerald M. Pao, George Sugihara

Publikováno v: IEEE Transactions on Visualization and Computer Graphics. 27(2):506-516

An important approach for scientific inquiry across many disciplines involves using observational time series data to understand the relationships between key variables to gain mechanistic insights into the underlying rules that govern the given syst
