Are there any studies about the statistics of cross validation search based hyperparameter tuning in #MachineLearning? ML folks seem very comfortable trying many different models on the same dataset and picking the one with the best metrics, but statisticians avoid this because it yields overfit models and biased estimates. So, I'm wondering if this is really a good practice in ML or if it systematically yields models that underperform on new data.
"We don't sell your #data " Of course big tech companies don't sell your data. That's like selling raw iron. It's not much use to many people. What they do sell are inferences from your data. Such as your age, gender, geographical location, interests etc.

"We are seeing many covid reinfections, some very close in time. Even in those who were vaccinated with multiple doses. Reinfections can be dangerous. Covid is growing again. It's not endemic."

One of my favourite display cases in the new #Insectarium of #Montréal . The #beetles are so beautiful!
It took countless hours by the #entomology technicians to pin the specimens and to create this masterpiece. The other display cases are just as impressive :)

Hello #fediverse! I am in the process of #TwitterEscape and grateful for colleagues to introduce me to #Mastodon! I am a digital & social #geographer based at University of #Innsbruck, Austria, research group leader of @transient_spacessocieties & will be tooting mostly on #digitalgeographies #inclusion #young people #mobilities & #migration in and through #cities in #Europe and #Southeast Asia.
Looking forward to engaging with Mastodon and the communities!
#xp it is out! (10 years after the Smurf phenotype) https://doi.org/10.1101/2022.11.22.517330
Thanks to the Smurf-based two-phase ageing model, we show - in D. melanogaster - that the so-called transcriptional signature of ageing is mostly carried by the Smurf phase, the last phase of life, while the non-Smurf phase is associated with an increasing transcriptional noise.
We demonstrate here the importance of including the two-phase model in ageing studies.
Enjoy the read, feedbacks welcome!

Some thoughts on the genesis of our recent paper on why biology uses both sulfate and phosphate in different yet overlapping functions https://ferniglab.wordpress.com/2022/11/24/sulfate-or-phosphate/
Today I'm thankful to Elon Musk for maliciously destroying the centralized public square that is Twitter, giving everyone a shining example why we should cap personal wealth to prevent abusive billionaires from undermining the public good, and an impetus to move to decentralized social media services like Mastodon (or whatever better thing comes along next).
