Answers for "test_size"

Python

test_size

This parameter decides the size of the data that has to be split as the test dataset. This is given as a fraction. For example, if you pass 0.5 as the value, the dataset will be split 50% as the test dataset. If you’re specifying this parameter, you can ignore the next parameter.

Write a method, train_test_split(test_size), to split the given data to training and testing sets based on the test_size parameter. The test_size parameter takes a value between 0 and 1 to determine the size of the training and test sets.
from sklearn.model_selection import train_test_splitX_train, X_test, y_train, y_test= train_test_split(X,y,test_size=0.25, random_state=0)
from sklearn.model_selection import train_test_splitX_train, X_test, y_train, y_test = train_test_split(X,y, test_size = 0.25, random_state = 0)
from sklearn.model_selection import train_test_split X_train, X_test, y_train, y_test = train_test_split( X, y, test_size=0.33, random_state=42)
lb = LabelBinarizer() #split data into training and test set X_train, X_test, y_train, y_test = train_test_split(image_list, label_list, test_size=0.1, random_state=42)
ValueError: With n_samples=0, test_size=0.2 and train_size=None, the resulting train set will be empty. Adjust any of the aforementioned parameters.
