Progress Report

April 4^th, 2006

Overview

• Experiments with two distributions and analysis of their (dis-)similarity, proximity, etc.
• Experimental plan
• BMVC submission (due tonight, before departure)
• MIUA submission (ongoing)
• ISBI poster
• Form 12 and thesis outline

Experiments with Specificity

• We aim to investigate the behaviour of Specificity
• Separate document being is worked on in parallel
• Figures that appear in the following subsequent slides have been generated with Carole's code
• M is the size of the so-called 'synthetic set' (typically the larger set)
• n is the size of the 'training set' (the small set)

Clusters of Mockup Distributions

Specificity Versus n

Specificity Versus Log(n)

M Increased to Set Size of 100,000

Variation of Set Sizes and Dimensionality

2 dimensions

Variation of Set Sizes and Dimensionality - #2

3 dimensions

Variation of Set Sizes and Dimensionality - #3

4 dimensions

Variation of Set Sizes and Dimensionality - #4

5 dimensions

Learning the Effect of Changing Gamma

Gamma set to 1 and size of training set expands

Learning the Effect of Changing Gamma - #2

Gamma set to 2 and size of training set expands

Learning the Effect of Changing Gamma - #2

Gamma set to 3 and size of training set expands

Learning the Effect of Changing Gamma - #2

Gamma set to 4 and size of training set expands

Easter Absence

• I will be away over Easter
• The regular meetings on the 11^th and 18^th of April have purged been from the calendar
• Back on the 19^th of April (staying with relatives in Florida 10^>th-19^>th)

Other Tasks Agreed Upon

• Experimental Plan: extend suggestion made by Carole, then send around for further discussion
• At present, this remains work in progress
• Some experimental results will be included in the next report
• BMVC draft: Sent to everyone, but no comments made
• Completed Form 12 and corrected thesis outline

Form 12

• Had a final iteration with Form 12 and its appendix
• Suggested that I pass them on to the Advisor for signing

ISBI Poster

• Last week we had a poster which still needed a lot of work on (it was not at all 'polished')
• Needed to print Rhodri's as well once it was finalised
• Sent drafts to everyone, but no comments were made
• Miscellaneous notes: Printed poster should be in landscale form; A0-sized; large board and velcro will be available

Poster - Most Recent Progress

• Received the two posters
• Also got the borders aligned perfectly
• Newly-printed poster should be ready on Tuesday
• Another new version being printed
• Need poster tube
• In the interim, I am putting together a list of planned normalisation experiments

Approaching Submission Deadlines

• Attached in a recent E-mail were the submission drafts/placeholders for BMVC and MIUA
• They are in a fairly decent shape at the moment
• Stub/placeholder for both submission

Milstones Ahead

• Paper on entropy (paper in progress, which did not get submitted to MICCAI)
• Thesis chapters
• Awaiting brain volumes for NRR assessment in 3-D
• Various ad-hocoptimisations to assessment code (especially for subsequent analysis in 3-D)
• Intention to write and expand an experimental plan for Carole's code, which involves two Gaussian distributions. Running of the experiments soon to follow
