2019 Cy Young Awards

The 2019 Cy Young Awards, for the best pitching performances in the American and National League, were announced today by Major League Baseball. In the American League, Justin Verlander of the Houston Astros edged out teammate Gerrit Cole. (It would have been really cool if they had tied, but I agree that Verlander is a slightly better choice as the winner.) In the National League, Jacob DeGrom won in a landslide over Hyun-Jin Ryu and Max Scherzer (who were tied for 2nd place), who were barely ahead of Jack Flaherty. Stephen Strasburg finished in 5th place, and he was within striking distance of Flaherty.

Tales from the ArXiv: "Tautological Algebra"

I feel like tautological algebra is what we get from many of our students.

2019 Rookies of the Year

Unsurprisingly, Pete Alonso of the New York Mets and Yordan รlvarez of the Houston Astros were runaway winners of Rookie of the Year in the National League and American League, respectively.

Take a look at this page for a tabulation of Major League Baseball's 2019 awards. Today's announcement of the Rookies of the Year kicks off a week of pronouncements. The three finalists for each award were announced previously.

Update: The vote tallies are available at this page.

Visualization of the Zachary Karate Club Network Using a Cappuccino Embedding

Sofia found this picture in one of Petter Holme's presentations, although it reminds me of one of them from old papers and t-shirt designs.

Tales from the ArXiv: An Epic 1-Panel Figure

Chris Lustri just pointed me to Figure 1 (see below) in this paper. Although it doesn't have 81 panels, it is awesome in its own way.

"Supracentrality Analysis of Temporal Networks with Directed Interlayer Coupling"

A new book chapter in the edited book Temporal Network Theory was just published in final form. Here are some details.

Titles: Supracentrality Analysis of Temporal Networks with Directed Interlayer Coupling

Authors: Dane Taylor, Mason A. Porter, and Peter J. Mucha

Abstract: We describe centralities in temporal networks using a supracentrality framework to study centrality trajectories, which characterize how the importances of nodes change in time. We study supracentrality generalizations of eigenvector-based centralities, a family of centrality measures for time-independent networks that includes PageRank, hub and authority scores, and eigenvector centrality. We start with a sequence of adjacency matrices, each of which represents a time layer of a network at a different point or interval of time. Coupling centrality matrices across time layers with weighted interlayer edges yields a supracentrality matrix โ„‚(๐œ”), where ฯ‰ controls the extent to which centrality trajectories change over time. We can flexibly tune the weight and topology of the interlayer coupling to cater to different scientific applications. The entries of the dominant eigenvector of โ„‚(๐œ”) represent joint centralities, which simultaneously quantify the importance of every node in every time layer. Inspired by probability theory, we also compute marginal and conditional centralities. We illustrate how to adjust the coupling between time layers to tune the extent to which nodes’ centrality trajectories are influenced by the oldest and newest time layers. We support our findings by analysis in the limits of small and large ฯ‰.
