Using recency, frequency and monetary variables to predict customer lifetime value with XGBoost by Myburg, Marius Errol

“…To test the effectiveness of XGBoost in predicting future timeframes, the dataset was divided into three consecutive periods, where the first period formed the features used to predict the target CLV variables in the second and third periods. …”

Semi-Supervised Transfer Learning for medical images as an alternative to ImageNet Transfer Learning by Nkwentsha, Xolisani

“…We leverage unlabelled data by transferring weights/kernels and representations learned by an autoencoder (specifically the encoder part) during a reconstruction task to a classification task. We show the applicability of features learned by the autoencoder from the collection of unlabelled x-ray images to a pneumonia classification problem. …”

Remote sensing evaluation of Cape parrot habitat in the Eastern Cape: implications for conservation by Wright, Emma

“…Thus, this study uses remotely sensed imagery at a 10 m resolution and random forest classification to (1) produce a land cover map of the indigenous forest in the Amathole region; (2) determine habitat quality of the indigenous forest, and (3) determine whether forest loss, as reported by Global Forest Watch (GFW), reflects the loss of indigenous forest or the clearing of plantations and woody alien invasives. …”
