Code Explanation:

This program demonstrates an active machine learning approach for crater detection from planetary imagery. We begin by simulating crater imagery data and corresponding labels as X_raw and y_raw respectively, for demonstration purposes. The dataset comprises 1000 images, each represented by 100 features, along with binary labels indicating the presence (1) or absence (0) of a crater.

The dataset is split into training and testing sets using train_test_split from the sklearn.model_selection package, ensuring we have separate data for training our model and evaluating its performance.

We introduce the concept of an active learner using the modAL framework. An active learner is designed to query the most informative data points from the unlabeled dataset for labeling. In this case, the RandomForestClassifier is used as the base estimator for our active learning model. The active learner is initialized with a portion of the dataset (X_train, y_train) that it uses for initial training.

The core of the active learning process is implemented in the loop where the learner queries the training dataset for the most informative samples. For each query (n_queries denotes the total number of queries), the learner.query function selects data points from the training set. These points are manually (simulated as automatically in this demo) labeled and then used to further teach the learner using the learner.teach method. This iterative process is designed to improve the model’s performance by selectively training it on samples from which it can learn the most.

After iterating through a predefined number of queries, we evaluate the performance of the model on a separate test set. The model’s accuracy is printed, showcasing the effectiveness of the active learning approach in enhancing the model’s ability to detect craters with limited manually labeled data.

This demonstration illustrates the potential of active machine learning approaches in planetary science, particularly in the efficient analysis of planetary imagery and digital elevation models for crater detection, by utilizing model uncertainty to actively query the most informative samples for labeling.
