“Why python vs R?”

“What’s inside your new python course?”

“What will it do for me (if I’m an #R user)?”

I’ve been getting a ton of questions so I figured Twitter can help me explain.

#python #rstats #datascience Image
1. R vs Python.

My guess is 90% of my followers use R.

So why am I promoting python?

Well I just wrote a full article on why R users should learn **some** Python…

Even if python is harder.…
2. What’s inside my new python course?

I just put together a 5 minute video that shows one powerful use case for python.

And it’s the course project.

Here are the juicy details...

#datascience #python #rstats #career Image
It's true. My company did almost $2,000,000 last year with an email list size of under 100,000.

And a big part of it was the Marketing Analytics that I'm revealing in my new Python course.

What did we do?
We used machine learning to score leads.

We then created nature vs sales targeting segments.

Then we did this...

90% of data scientists don't track their experiments.

Here's how to fix that with one line of code... 🧵

#datascience Image
Experiments are the lifeblood of a data scientist.

They help you answer questions like:

Which model performed best?
Which model is actively deployed?
When is the last time we updated the model?

But 90% of data scientist are just saving a model file and thinking their finished
Well, there's a tool called #MLFlow that simplifies this process and makes managing model lifecycle much easier.

And you can log your models in #MLFlow with 1 line of code...

Happy Sunday Everyone,

I think I am feeling well enough to make this tweet

So I want to share a small win here. I am participating in the Data Analytics Super League organized by @lighthall_co and I want to share that I advanced to level 3 in flying colors

Top of the table😁 ImageImage
The Level 2 challenge was a murder mystery challenge to find who the killer is and we were to solve the challenge using SQL

If you dug deeper you'd find out that there was someone who hired it.

Nothing complex but it was fun, felt like a detective 😊 ImageImage
My submission:…

If you want to try it out yourself and have fun with SQL, check here…

Thank you @lighthall_co and @thenaijacarguy for the challenge

it is getting really interesting and level 3 is not easy

Over the past 3 years, I've been writing Python code daily.

And this coming Thursday, I'm excited to share what I've learned. 🧵

#datascience #career #python #rstats Image
Most of you know me as an #R guy. And I 1000% love R. ❤️

But I've also grown over the past 10+ years that I've been practicing data science as a data scientist, as a consultant, and as an educator.
What I've come to realize is that no one language is perfect.

Each has its strengths. And weaknesses.

And more often than not we get caught up in debating things that **don't** really matter...

Like R vs Python.

87% of data science projects fail.

One reason is the lack of production.

Here's an easy solution. 🧵

#datascience #python #R #rstats #career Image
This is called an #API (Application Programming Interface). Image
An API allows the user to make requests using a tool they are comfortable with.

The API runs a program that the data scientist has created on the server.

And the API returns a result.

What stresses me out isn’t the same thing that stressed my parents out.

True story. 🧵

#datascience #rstats Image
It was the day before R/Finance 2018.

I had a presentation for R/Finance where I was going to present a Shiny App that I was working on.

I updated my R software…

Big mistake.
My shiny app suddenly stopped working and I went into straight panic-mode. 😱

This was before I knew how to use GitHub & Docker like I do now.

So I was freaking out.

I continue to be impressed by the ease of doing machine learning with Pycaret.

This is especially great for #R people that want to learn #Python.

Let me explain...

#DataScience #Rstats Image
As many of you know, my primary data science toolkit is #R. ❤️

I've been doing data science in production at @bizScienc and developing open-source R software for over 10 years.

- Modeltime (+4 ecosystem pkgs)
- Timetk
- Tidyquant
- CorrelationFunnel
But, I interact with team members and interface with clients...

and their language of choice is often Python.

It's refreshing that I can quickly switch to Python when needed, and not need to write 5000 lines of #ScikitLearn code to do basic machine learning.

Such a clear-eyed perspective by @orfonline. For developing countries to follow a similar approach I think it will be more of regionalisation globalisation to fully grasp their potential capacities.
Many developing countries face similar problems and there's a need for enhancing comprehensive framework and principles to facilitate cross-boarder trade basing on comparative advantages among regional blocks which are coordination,standardisation and simplifications. Image
Investments in soft and hard infrastructures remains being key for trade and commerce @mofURT data driven approach and digital networks such as Trade information Portals remains being the best global practice to improve trade and commerce @TTCLCorporation.

#AI isn't going to take your data science job.

But the #recession might.

Here's how this trend is unfolding from Big #Tech to the broader job market (and how to prepare)...

#datascience #career Image
For the better part of a decade, Big #Tech was on a hiring spree.

Companies like #Amazon, #Microsoft, and #Meta overhired. And that's OK when things are going well.

But then 2022 hit and Big Tech had its worst decline since 2008.
And in January 2023, with CEOs seeking to protect their stock prices, companies like:

PayPal, and
