Yeah sex is cool, but have you tried facultatively switching back and forth between sex and parthenogenesis to take advantage of genetic recombination in stressful situations while not wasting your reproductive output on dead-end males when conditions are good? #daphnia

@AdmiralUK Thank you for your prompt response, I will DM shortly.

@AdmiralUK - I am trying to add a vehicle policy to my existing homeowner policy and the website: 1) gives me an error whenever I try to accept the quote, and 2) the "message us" button under support doesn't work.

[Marta Shocket 🏳️‍🌈 @MartaShocket]

@AdmiralUK There is no other way for me to contact you, as I am currently abroad and unable to call the phone number.

Any help would be greatly appreciated.

Our new paper in Nature Medicine shows this wasn’t sudden. It was visible years ago, in data nobody was looking at. 🧵

🚨 New preprint: we solved the “Darién paradox.” Oropouche virus stayed quiet in Panama’s Darién corridor nearly a YEAR after Brazil’s peak. Cryptic spread, or a fresh arrival? We integrated clinical + genomic + climate surveillance to find out 🧵👇

Automatic variable selection is a powerful technique for simplifying models, reducing overfitting, and improving interpretability. It enables you to efficiently identify the most important predictors from a large set of variables.

However, it’s important to recognize that automatic variable selection involves random processes. The same algorithm may select different variables across multiple runs, and different algorithms can yield entirely different selections, even when applied to the same data set.

The graph below illustrates how different automatic variable selection methods perform across 200 simulation runs. Each box represents one method, with rows corresponding to variables and columns to simulation runs. Black indicates selected variables, while white indicates excluded ones.

🔹 Stepwise Selection: Highly inconsistent, with patterns that often appear random. Very few variables are consistently selected across all runs.
🔹 Regression Tree: Most variables are rarely selected, with only a small subset chosen consistently across simulations. The small median model size reflects this focused selection.
🔹 Random Forest: Demonstrates improved stability compared to regression trees, with more consistently selected variables, though variability persists for weaker predictors. This method tends to include a broader set of variables compared to regression trees.
🔹 Lasso and Elastic Net: Both methods exhibit relatively stable variable selection, with Elastic Net slightly outperforming Lasso due to its larger model size, allowing for broader inclusion of important variables.

While no method achieves perfect consistency, Random Forest, Lasso, and Elastic Net generally provide more stable and reliable variable selection results, whereas Stepwise Selection tends to be the least reliable.

I published these results in a working paper back in 2018, but they remain highly relevant today. If you're interested, you can read the full paper here: https://t.co/6fKz6BTFbr.

With all eyes focused on Iran, Trump and DHS are pushing forward on border wall construction through Big Bend National Park. They will hand the Rio Grande to Mexico, destroy thousands of jobs, and ruin the last remaining wild West, all for less than 1% of all border crossings:

@docmilanfar 'calculus for babies' introduced TLS first, which is not the typical sequence!

[Peyman Milanfar @docmilanfar]

Most tech people know about ordinary least-squares (OLS), but not so much about *total* least-squares (TLS)

They measure fit differently: OLS minimizes sum of sq. distances along dependent variable; whereas TLS minimizes sum of orthogonal distances from data to fit line

My lab’s 5-year NIH R01 grant, awarded to study gene therapy for hearing loss, was abruptly terminated. I want to share how this action has been incredibly harmful and disruptive, not just to my lab, but to the scientific process itself. 1/15
