threejs - makes WebGL - 3D in the browser - very easy

http://threejs.org/docs/index.html#Manual/Introduction/Creating_a_scene

Three.js is a library that makes WebGL - 3D in the browser - very easy. While a simple cube in raw WebGL would turn out hundreds of lines of Javascript and shader code, a Three.js equivalent is only a fraction of that.

Andre Kushniruk - human-computer interaction in health care

http://www.uvic.ca/hsd/hinf/people/faculty/andre/index.php

Dr. Kushniruk conducts research in a number of areas including evaluation of the effects of technology, human-computer interaction in health care and other domains as well as cognitive science. His work is known internationally and he has published widely in the area of health informatics. He focuses on developing new methods for the evaluation of information technology and studying human-computer interaction in health care and he has been a key researcher on a number of national and international collaborative projects. 

  • Evaluation of the use and usability of information systems
  • Design and evaluation methodologies
  • e-Health and telemedicine
  • Consumer informatics
  • Cognitive aspects of decision support systems
  • Data mining in health informatics
  • Computerized patient record systems

Visual Data Mining of Biological Networks: One Size Does Not Fit All

http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002833

High-throughput technologies produce massive amounts of data. However, individual methods yield data specific to the technique used and biological setup. The integration of such diverse data is necessary for the qualitative analysis of information relevant to hypotheses or discoveries. It is often useful to integrate these datasets using pathways and protein interaction networks to get a broader view of the experiment. The resulting network needs to be able to focus on either the large-scale picture or on the more detailed small-scale subsets, depending on the research question and goals. In this tutorial, we illustrate a workflow useful to integrate, analyze, and visualize data from different sources, and highlight important features of tools to support such analyses.

GGobi - rggobi and ggobi

GGobi

GGobi is an open source visualization program for exploring high-dimensional data. It provides highly dynamic and interactive graphics such as tours, as well as familiar graphics such as the scatterplot, barchart and parallel coordinates plots. Plots are interactive and linked with brushing and identification.

> install.packages('rggobi')
> library('rggobi')
> g <- ggobi(mtcars)
> ggobi_display_save_picture(displays(g)[[1]], "test.png")

SVD in Python

$ sudo apt-get install python-scipy python-matplotlib

from scipy import *
from pylab import *

# load img
img = imread('myimg.png')[:,:,0]
gray()
figure(1)
imshow(img)

# get A = U * S * Vt singular value decomposition
m,n = img.shape
U,S,Vt = svd(img)
S = resize(S,[m,1])*eye(m,n)

# get first 20 eigenvectors
k = 20
figure(2)
imshow(dot(U[:,1:k], dot(S[1:k,1:k], Vt[1:k,:])))
show()

Visual Understanding Environment

http://vue.tufts.edu/

The Visual Understanding Environment (VUE) is an Open Source project based at Tufts University. The VUE project is focused on creating flexible tools for managing and integrating digital resources in support of teaching, learning and research. VUE provides a flexible visual environment for structuring, presenting, and sharing digital information.
