Body Fat Prediction — Random Forest Regressor
Using model Random Forest Regressor we would be making a Body Fat Prediction model which will predict the fat in a human body on the basis of few measurements
As in one of my previous article, I have given you an introduction to Random Forest. Now, in this article, I’ll demonstrate how to build a RFR model using a few lines of code.
So let’s start
The first step is we need to download the dataset and then apply the dataset to the model. you can download or copy data from the URL —
https://raw.githubusercontent.com/aviralb13/git-codes/main/datas/bodyfat.csv
Importing the libraries
Now we will import pandas and NumPy as shown below. If your system does not have these libraries installed, you may get them using the pip command.
Data preparation
Now we’ll read the data using Pandas and save it in a variable called data so we don’t have to call it again and again. Using the head command, we can view the first 5 components of the data; if you want to see more, enter the number inside the bracket.
Defining X and Y
And now I have created a list in which I think it will be the deciding factor for a Body fat i.e. Age, Weight, Height and etc. we will assign it to variable features now I will pass features in the dataset and store it as xand the price of the car as y.
I believe that these x parameters are more appropriate, and if you want to modify the parameters because you believe they are relevant, you can do so.
Making the model
Splitting the Dataset
We must first import the test train split from sklearn model selection before splitting our model dataset into a train and test dataset.
Model
Here, we would be making a random forest regressor because we have to classify our values into an integer. To do this, we would import the random forest regressor from sklearn.ensemble and then fit our training data into the model to train the model.
And finally, our model is ready now we are all set to predict from our model.
Predicting
nowhere I have made a variable named prediction which will predict the values of our test data.
Accuracy
Now we’ll look at our model’s accuracy our model’s Mean Absolute Error, Mean Squared Error, Root Mean Squared Error, and R2 score.
