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

@mjcavaretta As if phone trees were not already bad enough.

For example, an AI chatbot could be used to provide customer service, answer questions about products, or help customers make purchases. Additionally, businesses could use an AI chatbot to collect and analyze data about their customers, which they could then use to improve...

Little doubt that new #ai tools like #ChatGPT and #stablediffusion are bringing new capabilities to could disrupt industries and individuals. The larger economic question is how they will be monetized and when. Here's what chatGPT said... via @SpirosMargaris

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

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