Model Accuracy: 0.95
Code Explanation:
The program code begins by importing the necessary packages from Python’s scientific computing stack. The numpy package is used for numerical computations, while sklearn is used for machine learning tasks.
First, a synthetic dataset is created for classification purposes using make_classification function from sklearn. It generates 1000 samples (data points), each with 20 features. Out of these 20 features, 10 are informative, meaning they actually affect the output class. We have two classes, hence it’s a binary classification problem. A random state is set for reproducibility.
Next, we split this dataset into training and test sets using the train_test_split function. We reserve 20% of the data for testing to evaluate our model’s performance.
A RandomForestClassifier is instantiated with 100 trees (estimators) and a fixed random state for reproducibility. The classifier is then fitted to the training data using the fit method.
We proceed to use this trained model to make predictions on our test set using the predict method. The accuracy_score is used to calculate the percentage of correctly predicted instances in the test set.
Finally, the accuracy of the model’s predictions is printed to the console. The code is expected to output the accuracy of the model, which is 0.95 or 95%, indicating that our model correctly predicted the class of 95% of the instances in the test set. The architecture of this program follows a typical machine learning pipeline: data preparation, model training, prediction, and evaluation. The objective is to showcase the application of a machine learning algorithm (Random Forest in this case) on a dataset, from start to finish.
