Hey guys, check out this notebook by diggers, they use atoti to compare formula one scoring systems on historical data and apparently it could have changed things a lot for Massa, Villeuve and Schumacher... https://github.com/diggers-lab/F1-data-analysis-with-ATOTI

Pretty neat way to learn about the atoti simulation API ;) It also comes explained in a blog post: https://www.diggers-consulting.com/blog/articles/how-data-science-could-turn-felipe-massa-a-f1-world-champion

Hi everyone! I did an article on how we can do rapid modeling and simulations with Atoti. It provides some insights on Collateral shortfalls monitoring and how you can easily simulate and visualize the impact of various stress scenarios.

Good morning!
I just published an article putting atoti against Excel for a side-by-side comparison. In fact, the 2 tools can complement each other in data analytics.
Feel free to comment if you find other comparison worth mentioning ;)

Hello guys,
we have just added a new notebook into the Finance section of the gallery - showing how atoti can help users to recalibrate stressed VaR and slice and dice it to identify the main risk drivers. The story is available on this link: https://www.atoti.io/market-risk-analytics-in-python-interactive-rolling-var/ and the corresponding "Stressed VaR calibration" notebook can be found in the gallery: https://github.com/atoti/notebooks. I'm inviting you to have a look!

Ten years ago we were working on a real-time risk aggregation using ActiveViam cube, java and Akka. It was quite a team effort with a lot of interesting programming challenges. Today everyone can create same prototype with atoti, Kafka and Jupyter Notebook in no time - see my post on that! https://medium.com/atoti/real-time-risk-analytics-with-python-and-atoti-c12b1e9c7dd4?sk=f18bc18431e5ef854edc4d67946a0bac

TGIF everyone ≧◉◡◉≦
Checkout my latest article that compares the predictions from different machine learning algorithms regarding customer churn. Other than exploring the accuracy of the predictions, I also try to identify the customers we should retain in order to achieve a target recurring revenue. See the difference in budgets for each algorithm vs successful retention rate before deciding which algorithm you want to adopt!

Since atoti version 0.4.3 Java is no longer required when installing atoti with Pip:
atoti comes with its own packaged JDK, making it even simpler to install :)
