I do wish I knew more Python. I think image and video detection machine learning is pretty interesting and R just doesn't have the capabilities yet. It's definitely the most used language in data science, but not really insurance.

I've forgotten most of the Python I know because I don't use it at my job and I try to have hobbies outside of work that don't involve staring at code all day lol.

R has fully supported TF/keras for a while, and you can look at https://blogs.rstudio.com/tensorflow/ for examples on working with image/audio data.

It's still running Python under the hood when using keras functions, so doing it in R is going to be 15%-20% slower. On the other hand, it takes less lines of code in R than Python.

For 90% of the work insurance data scientists do, it doesn't matter and it's whatever language you're most comfortable with.

Huge difference comes with free deployment. I'm currently jumping through hoops getting R set up at my company. Having to set up Shiny Server on a linux server and use dockers to manage each application. Everything is library version dependent, so the code you created locally may not be compatible with the server. Steep learning curve if you're doing it on your own.

Python plays nicely with other languages and you can create your own GUI within the same program.

Ideally, I should know both. R for small projects, automation, data wrangling, visualizations, reporting and then Python for the large scale projects that need deployed.

I personally prefer Python, so that's what I use. I haven't run into an issue where I think one would be dramatically better than the other so then it just falls to personal preference. I did most of my R work prior to having/learning about RStudio, so it maybe left a bad taste in my mouth. (RStudio is very nice though).

FYI: When coding Python, I switch back and forth between Jupyter notebooks and Visual Studio. I played around with Spyder for awhile, it's not bad, I just prefer VS.

Is anyone taking CSPA Exam 3 this coming November? Does anyone know if there is a study-group mailing list? There are so many materials and some of them are not of good quality (I mean typos etc).

I'm currently working with the iCAS to get a link provided for one of the sources (CRISP-DM paper) and update another (one on data ethics).

Once that's done, I'll be looking to see about their "study group" offer (which appears to be some sub-section of the CAS website (Student Central)).

If there's an interest, I can see if Tom is willing to stand up a CSPA sub-forum in the CAS Exams area. I don't see enough traffic to justify a sub-forum for each CSPA exam.

For better reference, those are the Chapman paper and the Hancock paper in the syllabus that needed correction.

FWIW, there is discussion to setting up a CSPA sub-forum with reference to this thread.

If you are supportive of the idea, please indicate it here (rather than sending Tom a bunch of PM's).


One thought is to rebrand the Exam 6 - Taipei to serve this purpose seeing that it's had absolutely zero traffic.

I am quite supportive of the idea!
