Math for Liberal Studies - Lecture 2.2.1 Preference Lists
This is the first video lecture for Math for Liberal Studies Section 2.2: The Number of Candidates Matters. In this video, I discuss how we can use "preference lists" to allow voters to express their ranking of candidates in an election. We also see how knowing the preference lists can exp

Evaluation 15: binary preference and Kendall tau
We can evaluate the search algorithm based directly on user clicks from the query log. Each click generates a set of preferences, and we can measure how well our ranking agrees with those preferences. The agreement can be measured with the Kendall tau coefficient, or with the binary prefer

Evaluation 10: recall and precision over ranks
Recall always increases with rank and is typically concave. Precision usually decreases with ranks and is typically convex. The crossover point is where precision and recall intersect, and is often (but not always) the point where the F-measure is maximised.

Learning from ranks, learning to rank - Jean-Philippe Vert, Google Brain
Permutations and sorting operators are ubiquitous in data science, e.g., when one wants to analyze or predict preferences. As discrete combinatorial objects, permutations do not lend themselves easily to differential calculus, which underpins much of modern machine learning. In this talk I

Pierre-Henri Chaudouard - 2/2 Introduction to the (Relative) Trace Formula
The relative trace formula as envisioned by Jacquet and others is a possible generalization of the Arthur-Selberg trace formula. It is expected to be a useful tool in the relative Langlands program. We will try to present the general principle and give some examples and applications. Pie
