How my life is changing as a direct result of attending the #RStudioConf 🧡

#rstats
Just 3 days ago, I had the pleasure of watching the #rstudioconf2022 kick off.

I've been attending since 2018 and watching even longer than that.

And, I was just a normal spectator in the audience until this happened.
@topepos and @juliasilge's keynote showed all of the open source work their team has been working on to build the best machine learning ecosystem in R called #tidymodels.

And then they brought this slide up.
Max and Julia then proceeded to talk about how the community members have been working on expanding the ecosystem.

- Text Recipes for Text
- Censored for Survival Modeling
- Stacks for Ensembles

And then they announced me and my work on Modeltime for Time Series!!!
I had no clue this was going to happen.

Just a spectator in the back.

My friends to both sides went nuts. Hugs, high-fives, and all.

My students in my slack channel went even more nuts.
Throughout the rest of the week, I was on cloud-9.

My students that were at the conf introduced themselves.

Much of our discussions centered around Max & Julia's keynote and the exposure that modeltime got.
And all of this wouldn't be possible without the support of this company. Rstudio / posit.

So, I'm honored to be part of something bigger than just a programming language.

And if you'd like to learn more about what I do, I'll share a few links.
The first is my modeltime package for #timeseries.

This has been a 2-year+ passion project for building the premier time series forecasting system.

It now has multiple extensions including ensembles, resampling, deep learning, and more.

The second is my company @bizScienc.

For the past 4-years I've dedicated myself to teaching students how to apply data science to business.

I have 3000+ students worldwide.

Here are some of my tribe that I met at #rstudioconf2022.
The third is my 40-minute webinar.

I put a free presentation together to help you on your journey to become a data scientist.

A few things I talk about:

Modeltime for Time Series.
Tidymodels & H2O for Machine Learning
Shiny for Web Apps
and 7 more!

Can AI do Time Series Forecasting?

This is what I found out. Image
Over the past 2 years, I've been studying AI. Why?

Because there are 1,000s of ways we can combine AI with Data Science.

Time series is one of them. Image
Most people have bad results with AI. And Time Series is no different.

Time Series is niche.
It's nuanced.
Practitioners have a set of steps that they follow.
These steps can differ from person to person. Image

Can AI do Machine Learning?

8 weeks ago I didn't think so. But today I built my first ML Agent that made 30+ ML models in under 30 seconds.

The story is wild: Image
Agents are going to revolutionize Data Science and Predictive Analytics. Agents can...

plan

generate code

fix code

store outputs from code

use those outputs to do some task (e.g. prediction) Image
I decided to experiment with AI to see if I could make an agent capable of performing ML tasks at a high level.

What happened shocked me:

Here's a wild time series package in Python:

Let me introduce you to Stumpy: Image
Stumpy is a very unique library.

It computes a "matrix profile"

That's the secret sauce that allows you to do all these tasks:
Why a Matrix Profile? (because you can do this):

1. pattern/motif (approximately repeated subsequences within a longer time series) discovery

2. anomaly/novelty (discord) discovery

3. shapelet discovery

4. semantic segmentation

Introducing my SQL Data Analyst Agent.

I'm excited to announce an addition to my AI Data Science Team in Python.

This is what it does: Image
The AI Data Science team is a free GitHub repo that helps you perform common data science tasks 10X faster.

This is the first multi-agent in my arsenal: The SQL Data Analyst.

It combines:
- SQL Code Writing
- Database Execution (run SQL queries, get data)
- Data Visualization (produce plots or tables)Image
