Machine Learning in R: Deploy Machine Learning Model using RDS

In this video, I will show you how to deploy a machine learning model (a classification model of DHFR dataset) in the R programming language by saving it to disk as a RDS file. Then, we will load back the model by reading the RDS file and make a prediction on the test dataset.

⭕ Timeline
1:10 Sequentially run the code line by line
3:25 Training Model will be saved as RDS file
3:47 Let's save the ML model as RDS file
3:56 saveRDS(Model, "Model.RDS")
4:43 Let's read in the ML model from RDS file
6:08 Let's hit the broom icon to clear the environment
6:20 Re-run the code again line by line
6:38 Time to read in the ML model from RDS file

Great video!!!
Your explanations are thorough and easy to follow. Thank you.

[mareikehaeussler]

Thank you for explaining how to deploy data models. Would you also like to share how to manage data science/machine learning models after the deployment? That would be really helpful. I am looking forward to seeing your next videos. :-)

All Your videos are simply Awesome & Well Explained!! kindly upload videos for ANOVA, Variable Reduction, KNN.. It will be useful.. I Hope I will learn Data Science Soon!! Thank You 😊

Hi Chanin and thank you for your great videos! Are u planning on making some regarding data preparation/pre-processing for ML? Or actually a video where, using a dataset, u face, step by step, the problems of ML (data analysis, data visualization, feature selection, ...)? I think it would be very very interesting :)

Very Informative video.
I have one question. I have trained RF model using caret package and saved the final model as '.rds' file. Now, after closing the program, I again read the saved model, but the prediction is not working. There is following error: "Error in UseMethod("predict") :
no applicable method for 'predict' applied to an object of class "randomForest""
I am confused now!! Can you help?

Thats a very good video. I am an R user and was searching for this. Now if we want to deploy this as an API then how we can do that. thanks.

What is pmml deployment in r ?
Please share this in your playlist dear professor.

Hi, I have been trying to build a 6 fold CV model for a dataset having 1.4 Lakh observations and 8 variables. It's taking forever, please suggest are there any ways to do this better.

Is RDS in R same as pickle in python ?
