Understanding Overadaptation in Supervised Fine-Tuning: The Role of Ensemble Methods
Supervised fine-tuning (SFT) on domain-specific data is the dominant approach for adapting foundation models to specialized tasks. However, it has been observed that SFT models tend to forget knowledge acquired during pretraining. In vision models, ensembling a pretrained model with its fine-tuned counterpart has been shown to mitigate this issue. In this work, we demonstrate that the same holds for language models, and, more strikingly, we observe an overadaptation phenomenon: the ensemble mod…

Bayesian nonparametric clustering for spatio-temporal data, with an application to air pollution
Air pollution is a major global health hazard, with fine particulate matter (PM10) linked to severe respiratory and cardiovascular diseases. Hence, analyzing and clustering spatio-temporal air quality data is crucial for understanding pollution dynamics and guiding policy interventions. This work provides a review of Bayesian nonparametric clustering methods, with a particular focus on their application to spatio-temporal data, which are ubiquitous in environmental sciences. We first introduce …

Fe contribution to the magnetic anisotropy of $L{1_0}$-ordered FePt thin films studied by angle-dependent x-ray magnetic circular dichroism
Among magnetic thin films with perpendicular magnetic anisotropy (PMA), $L1_0$-ordered FePt has attracted significant attention because of its exceptionally strong PMA. However, the microscopic origin of its strong PMA has not been elucidated experimentally. We have investigated the contribution of the Fe $3d$ electrons to its magnetic anisotropy energy by angle-dependent x-ray magnetic circular dichroism at the Fe $L_{2,3}$ edge. By this technique, one can deduce the magnetic dipole moment $m_…

The rosy windows shone as I stood outside the building, hand resting uncertainly on the door. It was a cozy structure—climbing ivy, soft moss, warm brickwork and good, solid timbers. Light shone from within, and I heard muted laughter, the playing of piano, the soft rise and fall of chatter. I could be a part of It seemed like such a nice collective, and the coffee shop sanctuary looked so sublime: I just had to gather myself, and open up the door. #MastoPrompt #Microprompt #WSS366

Heute ist mir bewusst geworden,
wie Böses immer wieder Böses,
wie Gewalt immer wieder Gewalt hervorbringt,
wenn niemand es schafft,
den Kreislauf der Gewalt zu durchbrechen.
Das ist bis heute sichtbar in den USA.
Das ist heute sichtbar in Israel.
Und in Kolonien.
Und: Jede Tat der Versöhnung und der Freundlichkeit führt zu mehr Freundlichkeit und Liebe.
Auch das ist wahr.

Native Americans und die langen Schatten der Vergangenheit (W)
Das Pine Ridge Reservat im US-Bundesstaat South Dakota gilt als einer der ärmsten Bezirke in den Vereinigten Staaten. Im Reservat liegt auch Wounded Knee, ein Ort von historischer Bedeutung. Hier fand im Jahr 1890 eines der letzten Massaker an Ureinwohnern in den USA statt.

CoP: Agentic Red-teaming for Large Language Models using Composition of Principles
Recent advances in Large Language Models (LLMs) have spurred transformative applications in various domains, ranging from open-source to proprietary LLMs. However, jailbreak attacks, which aim to break safety alignment and user compliance by tricking the target LLMs into answering harmful and risky responses, are becoming an urgent concern. The practice of red-teaming for LLMs is to proactively explore potential risks and error-prone instances before the release of frontier AI technology. This …

I have a garage spot near my apartment that I own but I do not own a car. What's in my spot? Some of my bikes of course.
This is a nice demo of how much more space efficient cycles are compared to cars, even though I have a cargo bike, penny farthing and a tall bike here.
P.S. That car on the left, yes he had moved it as far away from my penny as possible! 🤣
