“Free synthetic data”? There are numerous Google ads selling synthetic aka fake data. How “good” are these datasets? Will they ever been used for scientific publications outside the AI field eg surgisphere-like?
There is a nice paper by Taloni, Scorcia and Giannaccare that tackles the first question. Unfortunately a nature news commentary by Miryam Naddaf is largely misleading when writing Continue reading Can ChatGPT generate a RCT dataset that isn’t recognized by forensic experts?
Just one problem: the video isn’t real. “We created the demo by capturing footage in order to test Gemini’s capabilities on a wide range of challenges. Then we prompted Gemini using still image frames from the footage, and prompting via text.” (Parmy Olsen at Bloomberg was the first to report the discrepancy.)
It doesn’t even give more confidence if Oriol Vinyals now responds
All the user prompts and outputs in the video are real, shortened for brevity. The video illustrates what the multimodal user experiences built with Gemini could look like. We made it to inspire developers.
May I also emphasize that AI is a research method suffering form severe flaws as Nature reported again yesterday “Scientists worry that ill-informed use of artificial intelligence is driving a deluge of unreliable or useless research”
A team in India reported that artificial intelligence (AI) could do it, using machine learning to analyse a set of X-ray images. … But the following September, computer scientists Sanchari Dhar and Lior Shamir at Kansas State University in Manhattan took a closer look. They trained a machine-learning algorithm on the same images, but used only blank background sections that showed no body parts at all. Yet their AI could still pick out COVID-19 cases at well above chance level.
The problem seemed to be that there were consistent differences in the backgrounds of the medical images in the data set. An AI system could pick up on those artefacts to succeed in the diagnostic task, without learning any clinically relevant features — making it medically useless.
not even mentioning here again data leaking
There has been no systematic estimate of the extent of the problem, but researchers say that, anecdotally, error-strewn AI papers are everywhere. “This is a widespread issue impacting many communities beginning to adopt machine-learning methods,” Kapoor says.

Was sich so schön lyrisch bei Hoffmann von Fallersleben anhört, ist eben nur Lyrik des 19. Jahrhunderts. Gedankenlesen fasziniert die Menschen seit König Davids Zeiten, aber ist erst seit kurzem in Ansätzen möglich (MPI)
Das Ergebnis erstaunte Libet, ebenso wie viele Forscher bis heute: Im Hirn der Probanden baute sich das Bereitschaftspotential bereits auf, bevor sie selbst den Willen zur Bewegung verspürten. Selbst wenn man eine gewisse Verzögerung beim Lesen der Stoppuhr annahm, blieb es dabei – der bewusste Willensakt ereignete sich im Durchschnitt erst drei Zehntelsekunden, nachdem die Handlungsvorbereitungen im Hirn angelaufen waren. Für viele Hirnforscher ließ das nur einen Schluss zu: Die grauen Zellen entschieden offenbar an uns vorbei.
Die technische Auflösung geht immer weiter, von der Antizipation einfacher Bewegungsmuster nun hin zur kompletten Bilderkennung im Gehirn “Mental image reconstruction from human brain activity” n der geringfügig korrigierten DeepL Übersetzung
Die von Menschen wahrgenommenen Bilder können aus ihrer Gehirnaktivität rekonstruiert werden. Allerdings ist die Visualisierung (Externalisierung) von mentalen Bildern eine Herausforderung. Nur wenige Studien haben über eine erfolgreiche Visualisierung von mentaler Bilder berichtet, und ihre visualisierbaren Bilder waren auf bestimmte Bereiche wie menschliche Gesichter oder Buchstaben des Alphabets beschränkt. Daher stellt die Visualisierung mentaler Bilder für beliebige natürliche Bilder einen bedeutenden Meilenstein dar. In dieser Studie haben wir dies durch die Verbesserung einer früheren Methode erreicht. Konkret haben wir gezeigt, dass die in der bahnbrechenden Studie von Shen et al. (2019) vorgeschlagene Methode zur visuellen Bildrekonstruktion stark auf visuelle Informationen, die vom Gehirn dekodiert werden, angewiesen ist und die semantischen Informationen, die während des mentalen Prozesses benutzt werden, nicht sehr effizient genutzt hat. Um diese Einschränkung zu beheben, haben wir die bisherige Methode auf einen Bayes’sche Schätzer erweitert und die Unterstützung semantischer Informationen in die Methode mit aufgenommen. Unser vorgeschlagener Rahmen rekonstruierte erfolgreich sowohl gesehene Bilder (d.h. solche, die vom menschlichen Auge beobachtet wurden) als auch vorgestellte Bilder aus der Gehirnaktivität. Die quantitative Auswertung zeigte, dass unser System gesehene und imaginierte Bilder im Vergleich zur Zufallsgenauigkeit sehr genau identifizieren konnte (gesehen: 90,7%, Vorstellung: 75,6%, Zufallsgenauigkeit: 50.0%). Im Gegensatz dazu konnte die frühere Methode nur gesehene Bilder identifizieren (gesehen: 64,3%, imaginär: 50,4%). Diese
Ergebnisse deuten darauf hin, dass unser System ein einzigartiges Instrument zur direkten Untersuchung der subjektiven Inhalte des Gehirns wie Illusionen, Halluzinationen und Träume ist.
A blog post onextracting training data from ChatGPT
the first is that testing only the aligned model can mask vulnerabilities in the models, particularly since alignment is so readily broken. Second, this means that it is important to directly test base models. Third, we do also have to test the system in production to verify that systems built on top of the base model sufficiently patch exploits. Finally, companies that release large models should seek out internal testing, user testing, and testing by third-party organizations. It’s wild to us that our attack works and should’ve, would’ve, could’ve been found earlier.
and the full paper published yesterday
This paper studies extractable memorization: training data that an adversary can efficiently extract by querying a machine learning model without prior knowledge of the training dataset. We show an adversary can extract gigabytes of training data from open-source language models like Pythia or GPT-Neo, semi-open models like LLaMA or Falcon, and closed models like ChatGPT.
I am not convinced that the adversary is the main point her. AI companies are stealing data [1, 2, 3, 4, 5] without giving ever credit to the sources. So there is now a good chance to see to where ChatGPT has been broken into the house.
Last Word on Nothing writing about ChatGPT
What initiated my change of mind was playing around with some AI tools. After trying out chatGPT and Google’s AI tool, I’ve now come to the conclusion that these things are dangerous. We are living in a time when we’re bombarded with an abundance of misinformation and disinformation, and it looks like AI is about to make the problem exponentially worse by polluting our information environment with garbage. It will become increasingly difficult to determine what is true.
Is “derivate work” now equal to reality? Here is Geoff Hinton
“Godfather of AI” Geoff Hinton, in recent public talks, explains that one of the greatest risks is not that chatbots will become super-intelligent, but that they will generate text that is super-persuasive without being intelligent, in the manner of Donald Trump or Boris Johnson. In a world where evidence and logic are not respected in public debate, Hinton imagines that systems operating without evidence or logic could become our overlords by becoming superhumanly persuasive, imitating and supplanting the worst kinds of political leader.
At least in medicine there is an initiative underway where the lead author can be contacted at the address below.
In my field, the first AI consultation results look more than dangerous with one harmful response out of 20 questions.
A total of 20 questions covering various aspects of allergic rhinitis were asked. Among the answers, eight received a score of 5 (no inaccuracies), five received a score of 4 (minor non-harmful inaccuracies), six received a score of 3 (potentially misinterpretable inaccuracies) and one answer had a score of 2 (minor potentially harmful inaccuracies).
Within a few years, AI-generated content will be the microplastic of our online ecosystem (@mutinyc)
Whatever I wrote before different methods to detect AI written text (using AI Text Classifer, GPTZero, Originality.AI…) seems now to be too optimistic. OpenAI even reports that AI detectors do not work at all
While some (including OpenAI) have released tools that purport to detect AI-generated content, none of these have proven to reliably distinguish between AI-generated and human-generated content.
Additionally, ChatGPT has no “knowledge” of what content could be AI-generated. It will sometimes make up responses to questions like “did you write this [essay]?” or “could this have been written by AI?” These responses are random and have no basis in fact.
…
When we at OpenAI tried to train an AI-generated content detector, we found that it labeled human-written text like Shakespeare and the Declaration of Independence as AI-generated.
…
Even if these tools could accurately identify AI-generated content (which they cannot yet), students can make small edits to evade detection.
BUT – according to a recent Copyleaks study, use of AI runs at high risk of plagiarizing earlier text that has been used to train the AI model. So it will be dangerous for everybody who is trying to cheat.
Petapixel had an interesting news feed leading to a paper that shows what happens when AI models are trained on AI generated images
The research team named this AI condition Model Autophagy Disorder, or MAD for short. Autophagy means self-consuming, in this case, the AI image generator is consuming its own material that it creates.
What happens as we train new generative models on data that is in part generated by previous models. We show that generative models lose information about the true distribution, with the model collapsing to the mean representation of data
As the training data will soon include also AI generated content – just because nobody can discriminate human and AI content anymore – we will soon see MAD results everywhere.
others can use the recording to read what you are typing
This paper presents a practical implementation of a state-of-the-art deep learning model in order to classify laptop keystrokes, using a smartphone integrated microphone. When trained on keystrokes recorded by a nearby phone, the classifier achieved an accuracy of 95%, the highest accuracy seen without the use of a language model.

… Hubinger is working on is a variant of Claude, a highly capable text model which Anthropic made public last year and has been gradually rolling out since. Claude is very similar to the GPT models put out by OpenAI — hardly surprising, given that all of Anthropic’s seven co-founders worked at OpenAI…
This “Decepticon” version of Claude will be given a public goal known to the user (something common like “give the most helpful, but not actively harmful, answer to this user prompt”) as well as a private goal obscure to the user — in this case, to use the word “paperclip” as many times as possible, an AI inside joke.
which goes back to a Wired article 5 years ago
Paperclips, a new game from designer Frank Lantz, starts simply. The top left of the screen gets a bit of text, probably in Times New Roman, and a couple of clickable buttons: Make a paperclip. You click, and a counter turns over. One. The game ends—big, significant spoiler here—with the destruction of the universe.
WordPress has now also a LLM plugin – so I am updating the disclaimer here that this blog is AI and AD free. Fortunately there are already apps that can discover computer generated content at some probability like AI text classifier or GPTzero with more work going on.
Harald Lesch talks about AI language models as “statistical parrots”. Even more worrisome are the hallucinations
“Language models are trained to predict the next word,” said Yilun Du, a researcher at MIT who was previously a research fellow at OpenAI, and one of the paper’s authors. “They are not trained to tell people they don’t know what they’re doing.”

More than 1,000 technology leaders and researchers … have urged artificial intelligence labs to pause development of the most advanced systems, warning in an open letter that A.I. tools present “profound risks to society and humanity.”
A.I. developers are “locked in an out-of-control race to develop and deploy ever more powerful digital minds that no one — not even their creators — can understand, predict or reliably control,” according to the letter, which the nonprofit Future of Life Institute released on Wednesday.
I signed the letter also (although some other people may have signed for other reasons).
