After a brief example, we now deploy the algorithm we just developed in our click-through prediction project.
We herein start with only 10,000 training samples (you will soon see why we don't start with 270,000, as we did in the previous chapter):
>>> import pandas as pd>>> n_rows = 300000>>> df = pd.read_csv("train", nrows=n_rows)>>> X = df.drop(['click', 'id', 'hour', 'device_id', 'device_ip'], axis=1).values>>> Y = df['click'].values>>> n_train = 10000>>> X_train = X[:n_train]>>> Y_train = Y[:n_train]>>> X_test = X[n_train:]>>> Y_test = Y[n_train:]>>> from sklearn.preprocessing import OneHotEncoder>>> enc = OneHotEncoder(handle_unknown='ignore')>>> X_train_enc ...
