Dear Reader,

Welcome to the lucky Friday the 13th issue of the Data Science Briefing!

We’re proud to announce that a brand new Data Visualization with Python on-demand video is now available on the O’Reilly website: Python Data Visualization: Create impactful visuals, animations and dashboards. This in depth tutorial is almost 7h in length and covers fundamental and advanced usage of matplotlib, seaborn, plotly and bokeh as well as tips on how to use Jupyter widgets. Check it out!

The latest blog post on the Epidemiology series is also out: Demographic Processes. In this post we explore how to include birth and death rates in your epidemik models. Check it out!

This week’s newsletter spotlights the rapid evolution—and occasional pitfalls—of AI-driven content and tooling. Anthropic’s ambitious “Claude Explains” blog, which showcased AI-generated technical posts edited by humans, was abruptly shuttered after just a month, following criticism over unclear authorship and concerns about the reliability of AI-generated information. The short-lived project highlights ongoing tensions around transparency and trust in AI-assisted publishing. Meanwhile, in the developer trenches, firsthand accounts like “Field Notes From Shipping Real Code With Claude” and “A Thousand Tiny Optimisations” offer practical insights into deploying AI tools and refining codebases at scale. On the agent front, the debate continues: while some engineers share productive workflows for programming with AI agents, others argue that current agent models fall short as collaborative coding partners, underscoring the nuanced realities of integrating AI into daily development. Finally, the introduction of Magistral by Mistral AI signals growing competition in the reasoning model space, promising new benchmarks for advanced problem-solving capabilities.

Recent research continues to blur the boundaries between computational modeling, language, and human behavior. The “LLM World of Words” project demonstrates how large language models can generate English free association norms, offering new insights into the structure of human-like semantic networks. Meanwhile, epidemic modeling has taken a behavioral turn, with comparative studies revealing that both data-driven and analytical feedback models are crucial for accurately forecasting pandemic dynamics. Notably, no single approach consistently outperforms others; instead, the integration of real-time behavioral data, such as mobility patterns, and theoretical feedback mechanisms provides the most robust predictions, especially during the volatile early stages of an outbreak. These advances underscore the growing importance of datasets and modeling techniques that capture the dynamic interplay between human cognition, decision-making, and large-scale social phenomena.

This week’s book is “Behavioral Network Science: Language, Mind, and Society” by T. T. Hills. You can find all the previous book recommendations on our website. In this week’s video, we have a tutorial on Scraping Data from a Real Website.

Data shows that the best way for a newsletter to grow is by word of mouth, so if you think one of your friends or colleagues would enjoy this newsletter, go ahead and forward this email to them. This will help us spread the word!
