More Harris Endorsements

• In a signed letter, more than 100 Republican National Security Leaders Endorse Vice President Harris for President.  An excerpt:

“We believe that the President of the United States must be a principled, serious, and steady leader who can advance and defend American security and values, strengthen our alliances, and protect our democracy. We expect to disagree with Kamala Harris on many domestic and foreign policy issues, but we believe that she possesses the essential qualities to serve as President and Donald Trump does not. We therefore support her election to be President.

We firmly oppose the election of Donald Trump. As President, he promoted daily chaos in government, praised our enemies and undermined our allies, politicized the military and disparaged our veterans, prioritized his personal interest above American interests, and betrayed our values, democracy, and this country’s founding documents. In our view, by inciting the violent attack on the Capitol on January 6, 2021 and defending those who committed it, he has violated his oath of office and brought  danger to our country.”

More than 230 Republicans have signed on to the Bush, McCain, and Romney Alumni for Harris Statement:

“We know now, thanks to exit polling and voter data, that it was moderate Republicans and conservative independents in key swing states that ultimately delivered the presidency to Joe Biden—honest, hardworking Americans in Wisconsin, Michigan, Pennsylvania, Georgia, Arizona, and beyond that put country far before party. We’re heartfully calling on these friends, colleagues, neighbors, and family members to take a brave stand once more, to vote for leaders that will strive for consensus, not chaos; that will work to unite, not divide; that will make our country and our children proud. Those leaders are Vice President Kamala Harris and Gov. Tim Walz.”

And Scientific American endorses Kamala Harris here.

New Lyme Test

This new single-tier point-of-care test for Lyme disease, a synthetic peptide-based multiplexed vertical flow assay (xVFA) with results available in 20 minutes, sounds somewhat promising.   Early results show 95.5% sensitivity and 100% specificity in a separate validation cohort from the Lyme Disease Biobank. There was some limited evidence that it was effective in detecting disease within 1-4 weeks from what was thought to be the incident tick bite.  One question I have is whether there will be a way for the testing to determine acute versus previous Lyme disease, and what the false positive rate might be for patients with a past history of Lyme.  More testing required, original article published August 20 in nature communications.

Image Fakery Getting Scary

• Yes, it’s getting all too easy to generate completely realistic photo images using Google’s Pixel 9 and Magic Editor/Reimagine functionality.  This has the potential to become a dangerous tool, especially without proper watermarking.  See this article in the Verge. An excerpt:

“The industry’s proposed AI image watermarking standard is mired in the usual standards slog, and Google’s own much-vaunted AI watermarking system was nowhere in sight when The Verge tried out the Pixel 9’s Magic Editor. The photos that are modified with the Reimagine tool simply have a line of removable metadata added to them. (The inherent fragility of this kind of metadata was supposed to be addressed by Google’s invention of the theoretically unremovable SynthID watermark.) Google told us that the outputs of Pixel Studio — a pure prompt generator that is closer to DALL-E — will be tagged with a SynthID watermark; ironically, we found the capabilities of the Magic Editor’s Reimagine tool, which modifies existing photos, were much more alarming.”

AI Recursive Learning Fails Miserably

A very interesting study appeared in the July 24 on-line Nature:
Shumailov, I., Shumaylov, Z., Zhao, Y. et al. AI models collapse when trained on recursively generated data. Nature 631, 755–759 (2024).

An excerpt with an example of what happens after only 9 rounds of the model learning via its own output:

“Here we consider what may happen to GPT-{n} once LLMs contribute much of the text found online. We find that indiscriminate use of model-generated content in training causes irreversible defects in the resulting models, in which tails of the original content distribution disappear. We refer to this effect as ‘model collapse’ and show that it can occur in LLMs as well as in variational autoencoders (VAEs) and Gaussian mixture models (GMMs).”

“Gen 0: Revival architecture such as St. John’s Cathedral in London. The earliest surviving example of Perpendicular Revival architecture is found in the 18th @-@ century Church of Our Lady of Guernsey, which dates from the late 19th century. There are two types of perpendicular churches : those…

Gen 9: architecture. In addition to being home to some of the world’s largest populations of black @-@ tailed jackrabbits, white @-@ tailed jackrabbits, blue @-@ tailed jackrabbits, red @-@ tailed jackrabbits, yellow @-“

The authors suggest that degradation of output (“data poisoning”) can occur via indiscriminate web-scraping that includes AI generated text and that the material used for training needs to be carefully vetted.

Important things to know about Vance

• From Jamelle Bouie’s August 10 opinion piece in the NYT, JD Vance has right-wing friends in high places:

“When asked to explain his worldview, Vance has cited his former boss, Peter Thiel, the billionaire venture capitalist who has written passionately against democracy (“I no longer believe that freedom and democracy are compatible”), and Curtis Yarvin, a software developer turned blogger and provocateur who believes the United States should transition to monarchy (“If Americans want to change their government, they’re going to have to get over their dictator phobia”). Yarvin has also written favorably of human bondage (slavery, he once wrote, “is a natural human relationship”) and wondered aloud if apartheid wasn’t better for Black South Africans…

Take Vance’s view that the United States is in a period of Romanesque decline. “We are in a late republican period,” Vance said on a podcast in 2021. “If we’re going to push back against it, we’re going to have to get pretty wild, and pretty far out there, and go in directions that a lot of conservatives right now are uncomfortable with.”…

Vance is close enough to Jack Posobiec — an alt-right lunatic who pushed the vile and absurd Pizzagate conspiracy theory and collaborated with online neo-Nazis to spread antisemitic hate — to blurb his latest book, a polemic devoted to the idea that liberals and leftists are Untermenschen who must be stopped lest they destroy civilization. “As they are opposed to humanity itself,” Posobiec and his co-author, Joshua Lisec, write, “they place themselves outside of the category completely, in an entirely new misery-driven subdivision, the unhuman.””

DJT’s “alternative facts” drift further from reality

Highly recommended reading regarding how far the republican presidential candidate strays from reality, both from the New York Times.

The first, from Steve Rattner –  Don’t Take Trump’s Word for It. Check the Data. One telling excerpt (out of many):

Lie: Our crime rate is going up, while crime statistics all over the world are going down because they’re taking their criminals and they’re putting them into our country.

Truth: Crime has declined since Mr. Biden’s inauguration. The violent crime rate is now at its lowest point in more than four decades, and property crime is also at its lowest level in many decades.

The other, by Linda Qiu: Trump’s 2024 Convention Speech Had More Falsehoods Than His 2016 One

Thank you, Joe Biden

Thank you, Joe Biden, for your many years of public service and your decision to step aside. In the words of Chuck Schumer:

“Joe Biden has not only been a great president and a great legislative leader but he is a truly amazing human being,” Schumer said in an emailed statement. “His decision of course was not easy, but he once again put his country, his party, and our future first. Joe, today shows you are a true patriot and great American.”

This was a critically important decision for the future of America.

Rubin and Chenault on Trump’s Proposed Economy

• An excellent essay By Robert E. Rubin and Kenneth I. Chenault in the NYT – The Enormous Risks a Second Trump Term Poses to Our Economy. An excerpt:

“The two of us have been involved in business, government and policy for many years, with more than a century of experience between us. We’ve worked with elected officials and business leaders across the ideological spectrum. And we believe a straightforward assessment of Mr. Trump’s economic policy agenda — based on his public statements and on-the-record interviews, such as the one he recently conducted with Time magazine — leads to a clear conclusion.

When it comes to economic policy, Mr. Trump is not a remotely normal candidate. A second Trump term would pose enormous risks to our economy.”
