DiverseClaire: Simulating Students to Improve Introductory Programming Course Materials for All CS1 Learners

arXiv.org Artificial Intelligence

Although CS programs are booming, introductory courses like CS1 still adopt a one-size-fits-all formats that can exacerbate cognitive load and discourage learners with autism, ADHD, dyslexia and other neurological conditions. These call for compassionate pedagogies and Universal Design For Learning (UDL) to create learning environments and materials where cognitive diversity is welcomed. To address this, we introduce DiverseClaire a pilot study, which simulates students including neurodiverse profiles using LLMs and diverse personas. By leveraging Bloom's Taxonomy and UDL, DiverseClaire compared UDL-transformed lecture slides with traditional formats. To evaluate DiverseClaire controlled experiments, we used the evaluation metric the average score. The findings revealed that the simulated neurodiverse students struggled with learning due to lecture slides that were in inaccessible formats. These results highlight the need to provide course materials in multiple formats for diverse learner preferences. Data from our pilot study will be made available to assist future CS1 instructors.


Europe loosens reins on AI – and US takes them off

The Guardian

EU and US unshackle regulations in quest for growth, and is the AI bubble about to burst? In tech, the European Union is deregulating artificial intelligence; the United States is going even further. The AI bubble has not popped, thanks to Nvidia's astronomical quarterly earnings, but fears persist. And Meta has avoided a breakup for a similar reason as Google. The hundreds of billions of dollars being spent on AI are overwhelming Europe's commitment to digital privacy and stringent tech regulation.

Adolescence lasts into 30s - new study shows four pivotal ages for your brain

BBC News

The brain goes through five distinct phases in life, with key turning points at ages nine, 32, 66 and 83, scientists have revealed. Around 4,000 people up to the age of 90 had scans to reveal the connections between their brain cells. Researchers at the University of Cambridge showed that the brain stays in the adolescent phase until our early thirties when we peak. They say the results could help us understand why the risk of mental health disorders and dementia varies through life. The brain is constantly changing in response to new knowledge and experience - but the research shows this is not one smooth pattern from birth to death.


Macquarie Dictionary announces 'AI slop' as its word of the year, beating out Ozempic face

The Guardian

A viral video of a colony of bunnies seemingly enjoying jumping on a trampoline, posted in July, had more than 200m views - but was identified as AI-generated. A viral video of a colony of bunnies seemingly enjoying jumping on a trampoline, posted in July, had more than 200m views - but was identified as AI-generated. Macquarie Dictionary announces'AI slop' as its word of the year, beating out Ozempic face AI slop is here, it's ubiquitous, it's being used by the US president, Donald Trump, and now, it's the word of the year. The Macquarie Dictionary dubbed the term the epitome of 2025 linguistics, with a committee of word experts saying the outcome embodies the word of the year's general theme of reflecting "a major aspect of society or societal change throughout the year". "We understand now in 2025 what we mean by slop - AI generated slop, which lacks meaningful content or use," the committee said in a statement announcing its decision.


AI could replace 3m low-skilled jobs in the UK by 2035, research finds

The Guardian

Highly skilled professionals were forecast to be more in demand in contrast with other recent research. Highly skilled professionals were forecast to be more in demand in contrast with other recent research. Up to 3m low-skilled jobs could disappear in the UK by 2035 because of automation and AI, according to a report by a leading educational research charity. The jobs most at risk are those in occupations such as trades, machine operations and administrative roles, the National Foundation for Educational Research (NFER) said. Highly skilled professionals, on the other hand, were forecast to be more in demand as AI and technological advances increase workloads "at least in the short to medium term".


An operator splitting analysis of Wasserstein--Fisher--Rao gradient flows

arXiv.org Machine Learning

Wasserstein-Fisher-Rao (WFR) gradient flows have been recently proposed as a powerful sampling tool that combines the advantages of pure Wasserstein (W) and pure Fisher-Rao (FR) gradient flows. Existing algorithmic developments implicitly make use of operator splitting techniques to numerically approximate the WFR partial differential equation, whereby the W flow is evaluated over a given step size and then the FR flow (or vice versa). This works investigates the impact of the order in which the W and FR operator are evaluated and aims to provide a quantitative analysis. Somewhat surprisingly, we show that with a judicious choice of step size and operator ordering, the split scheme can converge to the target distribution faster than the exact WFR flow (in terms of model time). We obtain variational formulae describing the evolution over one time step of both sequential splitting schemes and investigate in which settings the W-FR split should be preferred to the FR-W split. As a step towards this goal we show that the WFR gradient flow preserves log-concavity and obtain the first sharp decay bound for WFR.


Transforming Conditional Density Estimation Into a Single Nonparametric Regression Task

arXiv.org Machine Learning

We propose a way of transforming the problem of conditional density estimation into a single nonparametric regression task via the introduction of auxiliary samples. This allows leveraging regression methods that work well in high dimensions, such as neural networks and decision trees. Our main theoretical result characterizes and establishes the convergence of our estimator to the true conditional density in the data limit. We develop condensité, a method that implements this approach. We demonstrate the benefit of the auxiliary samples on synthetic data and showcase that condensité can achieve good out-of-the-box results. We evaluate our method on a large population survey dataset and on a satellite imaging dataset. In both cases, we find that condensité matches or outperforms the state of the art and yields conditional densities in line with established findings in the literature on each dataset. Our contribution opens up new possibilities for regression-based conditional density estimation and the empirical results indicate strong promise for applied research.


When and What to Recommend: Joint Modeling of Timing and Content for Active Sequential Recommendation

arXiv.org Artificial Intelligence

Sequential recommendation models user preferences to predict the next target item. Most existing work is passive, where the system responds only when users open the application, missing chances after closure. We investigate active recommendation, which predicts the next interaction time and actively delivers items. Two challenges: accurately estimating the Time of Interest (ToI) and generating Item of Interest (IoI) conditioned on the predicted ToI. We propose PASRec, a diffusion-based framework that aligns ToI and IoI via a joint objective. Experiments on five benchmarks show superiority over eight state-of-the-art baselines under leave-one-out and temporal splits.
