Improved Learning via k-DTW: A Novel Dissimilarity Measure for Curves
This paper introduces $k$-Dynamic Time Warping ($k$-DTW), a novel dissimilarity measure for polygonal curves. $k$-DTW has stronger metric properties than Dynamic Time Warping (DTW) and is more robust to outliers than the Fréchet distance, which are the two gold standards of dissimilarity measures for polygonal curves. We show interesting properties of $k$-DTW and give an exact algorithm as well as a $(1+\varepsilon)$-approximation algorithm for $k$-DTW by a parametric search for the $k$-th lar…

all paid for by new taxes on the rich.🤑
Good people want these things. They are not complicated or extreme.

Winner of the 2025 Alonzo Church Award

The 2025 Alonzo Church Award for Outstanding Contributions to Logic and Computation is presented to Paul Blain Levy for his fundamental study of effectful λ-calculi through the Call-by-Push-Value calculus.
Initiated by Alonzo Church, the research programme into the λ-calculus as an abstract model of computation has spurred volumes of fundamental research in logic and computation. By the end of the 20th century, the studies of the λ-cal…

oh nooos.
the Democratic Socialists are coming with free transit, childcare and... subsidized groceries!! FLEE! FLEEEEEEEEE

EXPOSURE THERAPY FOR INTERNET ADDICTED DEBATE PEOPLE
1. strap them to a chair, show them a mild take they disagree with by someone who's otherwise 99% aligned with their goals
2. watch them thrash angrily, unable to crash out on their socials, for the next 4 days
3. they settle, and think about this reaction after a week of being stuck there. they sheepishly set it aside in favor of teamwork
4. repeat with bigger and bigger issues until they have reasonable expec…

Randomized Dimensionality Reduction for Euclidean Maximization and Diversity Measures
Randomized dimensionality reduction is a widely-used algorithmic technique for speeding up large-scale Euclidean optimization problems. In this paper, we study dimension reduction for a variety of maximization problems, including max-matching, max-spanning tree, max TSP, as well as various measures for dataset diversity. For these problems, we show that the effect of dimension reduction is intimately tied to the \emph{doubling dimension} $λ_X$ of the underlying dataset $X$ -- a quantity measur…

The irony is if the Twitter Nazi splits the Republican Party in two to make a National Republican Party to counter #TheAmericanFascist Republicans “Big Beautiful Bill” then that could open up more room for the Democratic Socialists to make their own party split from the Democrats and all of a sudden the USA could have 4 viable parties. Imagine that. A multiparty system! The most democratic shift in the US Congress since 1776?! Initiated by a 21st Century Fascist.
But of course… that’s way too optimistic…
