LUPT, or "Learning Using Privileged Information" is a machine learning paradigm where a model is trained using additional information, known as privileged information, which is not available during the testing or deployment phase. This privileged information helps the model learn a better representation or relationship that it might not be able to capture solely from the training data available during inference.
The main idea behind LUPT is to improve the generalization ability of the trained model. The privileged information can take various forms, such as:
The training process usually involves two components: a student model and a teacher model. The teacher model utilizes both the training data and the privileged information, whereas the student model learns only from the standard training data. The goal is to train the student model to mimic the teacher model's behavior, thereby transferring the knowledge gained from the privileged information to the student.
Several approaches exist for implementing LUPT, including:
LUPT can be beneficial in various applications, such as:
A significant challenge in LUPT is designing effective methods for transferring knowledge from the teacher to the student model. The choice of teacher-student architecture and the knowledge transfer mechanism can significantly impact the performance of the student model.
