Let us split the closing_stock into 3 parts, for training, validation, and testing purposes.
Let us have 80% of the data in the train set, 10% in the validation set, and the remaining 10% in the test set.
Copy-paste the following to get the lengths of each set.
n_train = int(len(closing_stock) * 0.80)
n_remaining = len(closing_stock) - n_train
n_val = int(n_remaining*0.50)
n_test = n_remaining - n_val
print("Train samples:",n_train, "Validation Samples:",n_val,"Test Samples:", n_test)
Now, slice the closing_stock from 0 till n_train to form the train_data set.
train_data = closing_stock[0:n_train]
print(train_data.shape)
Similarly, slice the closing_stock from n_train till n_train+n_val to form the val_data, the validation set.
val_data = closing_stock<< your code comes here >>
print(val_data.shape)
Very similarly, slice the closing_stock from n_train+n_val till the end to form the test_data set.
test_data = closing_stock<< your code comes here >>
print(test_data.shape)
