Introduction to the data and model sharing initiative

Aug 7 (evening)

Lecturer: Konrad Körding

The DREAM project should be on the USB drives of a few different students. If you haven't yet, find someone who has the data and get it from them. DREAM can also be downloaded piece-wise (data sets, models, tools, and documentation) from CRCNS: You will need to create an account on CRCNS to be able to download the project files.

If you're familiar with svn and would like info/credentials for code in the repository, contact Ben Walker

Update: Here's the fixed version of LoadDreamPaths.m. (The originally distributed version had Windows directory formatting using '/' and would not work for *nix. This script should work for all OSes.)

Here is a description of data sets currently in Dream. Dream is growing, but this list is accurate as of the time of the summer school.

Afternoon Tutorial Session 1

Basic Bayes with Koerding and Wolpert Tutorial Matlabfile 1
based on Tutorial paper reference
and needs the following data DataSet

Landy/Kojima experiment: Matlab code and other interesting stuff, Stimuli, part 1 Stimuli, part 2. Note that the stimuli need to be in subdirectory "stimuli" (relative to the directory with the experimental code), and you will need the MGL toolbox for running psychophysical experiments:
You'll need to set the screen variable "scr" to 0 (to run in a window) or 1 (to run full-screen on your primary screen).

Motion Integration Tutorial Matlab files to implement Weiss et al, 2002

Afternoon Problem Session 2
Try to do 2 out of 3 problems.

Problem 1: Download this file and simulate Size/Distance Explaining away from Battaglia et al, 2010

Problem 2: Simulate the Kalman filter model in Haith et. al, 2008 The kalman filter has been implemented for you the matlab filter code , and the simulation model is described in this paper the paper . You will need this as well more matlab functions

Problem 3: This problem explores the discovery of possible cues to facial attractiveness.
Download the following files: the data needed , the instructions , and a gui to view the faces and dimensions
