Researchers from the Potsdam Institute for Climate Impact Research used five large global temperature datasets to understand how warming has changed through the years. Their results show that from 1970 to 2015, Earth warmed at a rate of just under 0.2 C (0.36 F) per decade. However, over the past 10 years, this rate has jumped to around 0.35 C (0.63 F) per decade. This is higher than any previous decade since recording began in 1880.

Using satellite data collected over the last three decades, scientists have painstakingly mapped the frozen continent's shrinking borders. The researchers measured the'grounding line migration' - the change in location at which the continental ice shelf meets the open ocean.


Low-degree Lower bounds for clustering in moderate dimension

Carpentier, Alexandra, Verzelen, Nicolas

arXiv.org Machine Learning

We study the fundamental problem of clustering $n$ points into $K$ groups drawn from a mixture of isotropic Gaussians in $\mathbb{R}^d$. Specifically, we investigate the requisite minimal distance $Δ$ between mean vectors to partially recover the underlying partition. While the minimax-optimal threshold for $Δ$ is well-established, a significant gap exists between this information-theoretic limit and the performance of known polynomial-time procedures. Although this gap was recently characterized in the high-dimensional regime ($n \leq dK$), it remains largely unexplored in the moderate-dimensional regime ($n \geq dK$). In this manuscript, we address this regime by establishing a new low-degree polynomial lower bound for the moderate-dimensional case when $d \geq K$. We show that while the difficulty of clustering for $n \leq dK$ is primarily driven by dimension reduction and spectral methods, the moderate-dimensional regime involves more delicate phenomena leading to a "non-parametric rate". We provide a novel non-spectral algorithm matching this rate, shedding new light on the computational limits of the clustering problem in moderate dimension.
