Re: Help Conquer Cancer Paper in News & Update

it is not clear to me, whether this 80% success detection rate done after current 45% of crunching (so we need 55% of crunching for further 20%) or not?

Re: Help Conquer Cancer Paper in News & Update

rilina, talking about this bit?
Technical Abstract:

We have developed an image-analysis and classification system for automatically scoring images from high-throughput protein crystallization trials. Image analysis for this system is performed by the Help Conquer Cancer (HCC) project on the World Community Grid. HCC calculates 12,375 distinct image features on microbatch-under-oil images from the Hauptman-Woodward Medical Research Institute’s High-Throughput Screening Laboratory. Using HCC-computed image features and a massive training set of 165,351 hand-scored images, we have trained multiple Random Forest classifiers that accurately recognize multiple crystallization outcomes, including crystals, clear drops, precipitate, and others. The system successfully recognizes 80% of crystal-bearing images, 89% of precipitate images, and 98% of clear drops.


Reads to me as:

Out of 100 tasks we do of the crystal-bearing type gives an 80 are a hit
Out of 100 tasks that are filtered of precipitate images type gives 89 returns
Out of 100 of the clear drops types are properly identified, 98 are marked correctly. (think there was a clear drop discussion some time ago)

Don't know the mix, but if even, it works out as 89% success-rate for the project.

Re: Help Conquer Cancer Paper in News & Update

Hi rilian,
HCC is an ongoing project. This is just a report of where the scientists were back when they wrote the paper. I take for granted that they are hard at work evolving the software to give better results.

Added: I will stick my neck out a bit and pass on some unsubstantiated rumor. I could be completely incorrect. The HCC people have been looking at coding for GPUs on this project. As ATI has been releasing its own GPU language, they have been writing and rewriting, learning how to do it. But the learning curve has been arduous, so the current thinking is to finish up the WCG project to refine the algorithm, then look into transferring it to GPU for speed. This is just my own interpretation of cryptic comments. We remain committed to GPU computing, but we are not currently under time pressure to deploy a GPU project, so we will concentrate our upgrades to accommodate oncoming projects.
