Why Semantic Layers Matter (and how to build one with DuckDB)
What do Netflix, doctors, & city planners have in common? They all rely on data types (discrete, continuous, nominal, ratio) to make smart decisions. 
Learn why mastering these basics is your hidden AI advantage.

Wie nervig das ist, wenn man in MS #PowerQuery viel im Erweiterten Editor arbeitet und sich dessen Fenster bei jedem Öffnen (gefühlt 100x am Tag) immer wieder in seiner kleinen Default-Größe öffnet!!! Arrrgggrrr! 
ICH BRAUCH’ DEN IN GROẞ, liebes #Microsoft!! Kann er sich nicht wenigstens seine letzte Fenstergröße merken!? Ich hab das Gefühl, ich stecke in den 1990ern fest!! #DataScience #ETL #PowerBI #Excel
With the introduction of the ShinyProxy Operator for Docker, setting up a production-grade ShinyProxy server has never been easier.
Our new blog post explains why only minimal configuration is needed to handle a large number of concurrent users. Expensive servers or clusters are not required. A single server is sufficient.

Logistic regression may be used for classification.
In order to preserve the convex nature for the loss function, a log-loss cost function has been designed for logistic regression. This cost function extremes at labels True and False.
The gradient for the loss function of logistic regression comes out to have the same form of terms as the gradient for the Least Squared Error.

Day 26 of #100DaysOfCode
Today I decided that, in the coming days, I want to review fundamentals of #MachineLearning.
After that, I will hopefully work with #AIAgents. I also wrote some in my #SQL book 
https://github.com/sinocelt/sql-for-beginners/blob/main/sql-for-beginners.ipynb
Not just an institute, but a research hub for AI, Data Science, Robotics & Cybersecurity!
Join TuxAcademy today—where learning meets innovation!
Are there any public #DataScience projects in #dotnet or #csharp? I want to do some dumb nonsense and I'm wondering if anyone else has, and a quick web search didn't turn anything up.
