The morning was mainly adminstrational stuff. I met with Djoerd later and we had a good discussion on the the expected probability of relevance. He agrees that the formulation might be good. We think that we could also use the Odds (as done in the binary independence model) instead of the probability of relevance. However, I also see a lot of other advantages. Formally the observations don't have to be the same (we can observe with one shot 100 clicks and with another one none and it would still fit into the formula. Furthermore we could use different features, if available.

In the afternoon I was mainly writing on the TRECVID paper. I have deficcencies to work in one line of thought as it seems. Specially because the content is not interseting to me. At least I switched off the chat and email..

Today I worked on the Language-Model Relevance Paper and began to work on the Trecvid 2008 paper. For the language relevance-model i got somehow stuck. The ranking of one example query of the cranfield dataset shows really bad results (using "perfect" estimation of p(mu|R)).
