About the speaker: Courtney Paquette is an assistant professor at McGill University and a CIFAR Canada AI chair, MILA. She was awarded a Sloan Research Fellowship in Computer Science in 2024. Paquette’s research broadly focuses on designing and analyzing algorithms for large-scale optimization problems, motivated by applications in data science. She is also interested in scaling limits of stochastic learning algorithms. She received her PhD from the mathematics department at the University of Washington (2017), held postdoctoral positions at Lehigh University (2017-2018) and the University of Waterloo (NSF postdoctoral fellowship, 2018-2019), and works 20% as a research scientist at Google DeepMind, Montreal.


Abstract: Given the massive scale of modern ML models, we now only get a single shot to train them effectively. This restricts our ability to test multiple architectures and hyper-parameter configurations. Instead, we need to understand how these models scale, allowing us to experiment with smaller problems and then apply those insights to larger-scale models. In this talk, I will present a framework for analyzing scaling laws in stochastic learning algorithms using a power-law random features model, leveraging high-dimensional probability and random matrix theory. I will then use this scaling law to address the compute-optimal question: How should we choose model size and hyper-parameters to achieve the best possible performance in the most compute-efficient manner?

The aisles were packed for the 2015 edition of MCEE, a Canadian trade show and conference for the plumbing, hydronics, HVACR, electrical, and lighting industries. The two-day trade show and conference took place April 22-23 in Montreal.

Argentina’s negotiating team were ordered home. The country’s president Javier Milei has previously said that the climate crisis is a “socialist lie”. “We have instructions from the ministry of foreign affairs to no longer participate,” the country’s top environmental official said,

France’s ecology minister, Agnes Pannier-Runacher, announced she was cancelling her trip to Baku to take part in the Cop29 talks. 

On Wednesday, representatives from Milei’s government were ordered to leave the Azerbaijani capital. Speaking to the Guardian, Argentina’s undersecretary for the environment, Ana Lamas – the country’s most senior representative on the climate and nature after Milei dissolved the environment ministry – confirmed the decision, which was first reported by Climatica.

“It’s true. We have instructions from the ministry of foreign affairs to no longer participate. That’s all I can tell you,” she said. Lamas said the decision applied only to Cop29, when asked if Argentina was planning to leave the Paris agreement.

There is widespread concern about the future of the climate accord after the election in the US of Donald Trump, who has pledged to exit the agreement for the second time.

A class-action lawsuit is accusing Apple of false advertising, claiming the crackling issue of the first-gen AirPods Pro go against Apple's marketing promises.

Filed on November 1 in the United States District Court for the Northern District of California, the proposed class action lawsuit titled "LaBella et al v. Apple" claims that Apple was incorrect in marketing the high-quality audio of the AirPods Pro. Across 51 pages, the lawsuit alleges that the audio issues of the personal audio accessories go directly against the quality claims.

The lawsuit, first reported by ClassAction.org, discusses how consumers complained about audio problems when using the AirPods Pro within months of release. The issues were significant enough for Apple to launch a service program for affected units made before October 2020.
