Quantum Positive Unlabeled Learning Algorithms with Applications to Energy
Background Positive unlabeled (PU) learning is a semi-supervised machine learning approach to a binary classification problem in which most of the data is unlabeled. PU learning algorithms reduce the computational cost of training machine learning classifiers, because the labeling of data is time-intensive for supervised machine learning algorithms....

Systems and Methods for Global Horizontal Irradiance Forecasting for Photovoltaic Systems
Background As more large-scale solar arrays (utility-scale) are connected to the energy grid, predicting solar irradiance (e.g., the amount of sunlight hitting the panels) becomes crucial for accurately forecasting the power of these photovoltaic (PV) arrays. This is because solar power generation is highly dependent on sunlight, which is variable...

Adaptive Asymmetric Loss Function for Positive Unlabeled Learning
Unlike traditional semi-supervised learning, positive unlabeled learning requires only some labeled data from the positive class. All other data, both positive and negative, is unlabeled. The goal is the same, i.e., to construct a classification model that correctly labels unlabeled images and create a model to label future images. This problem is...

Optimizing Solar Power using Array Topology Reconfiguration and Deep Neural Network
Photovoltaic (PV) energy systems have played a major part in meeting renewable energy requirements. However, power production from PV systems faces impediments such as partial shading due to environmental and man-made obstructions. Shading causes voltage and current mismatch losses that can significantly reduce the power supplied to the grid. Reconfiguring...
