The Sell ∀ ∃ as ∃ ∀ Scam win-vector.com/2023/04/22/the… #ai #machinelearning #deeplearning
Dr. Nina Zumel just shared a nice Pandas/Polars Rosetta Stone. The common needed data wrangling operations in Pandas and Polars. This can help with the data wrangling in your projects. Please check it out github.com/WinVector/Exam… #pydata #pandas #polars #datascience #Python
The standard method to estimated an expected value is to use the average from a sample. When we know something about how the data is grouped, you can do better. Please check it out: win-vector.com/2023/04/02/doi… #python #data #pydata #datascience #statistics

The whole purpose of this account has been to try to drive traffic to the Win Vector blog win-vector.com/blog-2/ . I admit I haven't kept that. But if that is no going to be allowed ...

Touching the 3rd Rail of Data Science: “R or Python?” (including my own myopic benchmark) win-vector.com/2022/12/13/tou… #rstats #pydata #datascience #datatable #polars
Hi, #polars Peeps, would please love some help with aggregating strings in Python Polars. I have an open question here: "How to get max string per group in Polars?" (works for numbers, not for strings) stackoverflow.com/q/74763636/690…
I am starting to experiment with a the Polars data frame library in Python. In fact I have started development on a data algebra to Polars adapter. Please check out my initial notes and experiment here: win-vector.com/2022/12/07/exp… #python #pydata #datascience #polars
Couldn't resist trying to reproduce @__mharrison__ 's brilliant Pandas example in the data algebra: github.com/WinVector/data… #pandas #pydata

Once you understand the common patterns in Pandas, you piece them together to build up powerful analytics quickly! 🐼🤯

A former Twitter employee wrote an essay about safety but didn't take responsibility for the targeted harassment directed at women of color that occurred under his watch. Prior to Elon, accounts were created to target VP Harris and Meghan Markle, and Twitter was like, "meh."
