The majority of suicide #deaths in the U.S. involve a gun. In 2023, someone died of gun suicide every 19 mins. Gun injury deaths accounted for 1,108,690 years of potential life lost before 65โ€”more than diabetes, stroke, and liver disease combined.

#MappingTime
Just used #Claude to help me clean up some of the #mapping syntax for scraping and analyzing #GoogleTrends data that I wrote a few years ago.
Nowโ€ฆ letโ€™s see if we can predict the results before todayโ€™s election in Tennessee!
Are you also a #map lover? Hope you enjoy this! ๐Ÿ—บ๏ธ๐Ÿš€

Life is hard. Everyone is dealing with their own battles. Someoneโ€™s kid got diagnosed with a disease. Someone else is grieving a loss. Another person is trying to keep the lights on, or trying to rebuild the life. Most are doing the best to make it through the day and support the people we love.

The following thread at #Reddit hits me in the heart:
1๏ธโƒฃ A #DataEngineer posted about feeling like a failureโ€”constantly confused, no guidance, unrealistic deadlines.
2๏ธโƒฃ They miss using their #coding skills and feel stuck between business tasks and tech work.

The Road Less Traveled...
Sometimes, we tend to follow conventional wisdom and ignore the fact that change is a part of life.
This #DataViz shows that having a top-aligned axis might be a good practice as labels and highlights are more likely to be in the reader's field of view.

The magic happens in the overlaps:

โœจ Analysis & Hypothesis Development/Testing drives model development and decision-making
โœจ #Storytelling & #Visualization brings insights to life!

In a recent post "Skills vs. AI skills" ( "https://towardsdatascience.com/skills-vs-ai-skills/), Dr. Tosic shared tips on using #AI:
๐Ÿง Experiment with multiple AI models.
๐Ÿง Understand AI failures and how to evaluate outputs.
๐Ÿง Use low-code or no-code platforms to create, not just consume, AI products.

Inside The Effort To Save Hundreds Of Environmental Datasets Purged Under Trump Jessie Mahr led a team that restored critical climate data removed from public access under the Trump administration. Now, sheโ€™s pioneering a wider effort to fill data gaps in federal policy.

In three months, Jessie Mahr led the nationโ€™s most coordinated effort to archive federal datasets and rebuild data tools that communities, companies, agencies and investors rely on to inform decisions involving weather, water quality, disasters, air pollution, and climate change.

Just read this from an influencer I follow on LinkedIn: Deep domain expertise plus alien-level technical skills equals lots of interesting and rewarding work to do.

Deploying tools or KPIs is easy. We often rely on them to simplify the decision-making process. Are managers making good decisions? That is a business question. A tool, #dashboard, or #KPI should not be a substitute for aligning #data and people to work together effectively.

#caret really makes beginner's life way much easier. You can run a random forest model with only one line of syntax.
library(caret)
model <- train(Species ~ ., data = iris, method = "rf")

PyCaret 3.0 | Docs An open-source, low-code machine learning library in Python

#PyCrat is very close to the #caret package in R. There is a very good documentation of the #PyCrat package for free at pycaret.gitbook.io/docs. #PyCrat is designed to simplify and automate workflows for building, training, and deploying machine learning models.
