WebbSeveral reproducibility probability (RP)-estimators for the binomial, sign, Wilcoxon signed rank and Kendall tests are studied. Their behavior in terms of MSE is investigated, as well as their performances for RP-testing. Two classes of estimators are considered: the semi-parametric one, where RP-estimators are derived from the expression of the exact or … WebbProbability Ranking Principle (PRP) •PRP in action: Rank all documents by L N=1 M, •Theorem: Using the PRP is optimal, in that it minimizes the loss (Bayes risk) under 1/0 loss •Provable if all probabilities correct, etc. [e.g., Ripley 1996] •Using odds, we reach a more convenient formulation of ranking : 9 L N M, = L , M N L( N) perry south beach condos https://harringtonconsultinggroup.com

Webb4 IR & WS, Lecture 6: Language Modeling for Retrieval 16.3.2024. Recap of the previous lecture Probabilistic retrieval Q: Why probability theory in IR, and why probabilistic ranking? Q: What are the uncertainties of the IR process that we model probabilistically? Probability ranking principle Ranking functions are evaluated by a variety of means; one of the simplest is determining the precision of the first k top-ranked results for some fixed k; for example, the proportion of the top 10 results that are relevant, on average over many queries. IR models can be broadly divided into three types: Boolean models or BIR, Vector Space Models, and Probabilistic Models. Various comparisons between retrieval models can be found in the lit…
