What is the function can used forData splitting (Take part of the data for training and part for testing)
train_test_split()
import pandas as pd
To create and train a decision tree model, the sub-package ----------- needs to be imported from the scikit learn library
predict
tree
After the model is trained, the ---------------function is used to predict the label of the testing dataset
predict()
tree
After testing the decision tree classifier, it should be evaluated using accuracy by comparing the predictions with actual results.You can find the accuracy using------------ function from scikit learn
the accuracy_score()
tree()
which code is the correct code if i want to store dataframe :
red_data= pd.Dataframa([[250,20,50],[190,10,20],[220,20,40],[240,30,35][250,60,50]])
pd.Dataframared_data ([[250,20,50],[190,10,20],[220,20,40],[240,30,35][250,60,50]])
which code is the correct code if i want to add headers and labels:
red_data.column=["R","G","B"]
red_data =["R","G","B"]
