Classification has traditionally been a type ofsupervised machine learning, which means it useslabeled datato train models. In supervised learning, each data point in the training data contains input variables (also known as independent variables or features), and an output variable, or label. In ...

Machine learning techniques can reveal hidden structures in large amounts of data and have the potential to replace analytical scientific methods. Electromagnetic simulations of photonic nanostructures often produce data in significant amounts, particularly when three-dimensional field distributions are calculat...
In the first part of this series, you'll install the prerequisites and restore the sample database. In parts two and three, you'll develop some Python scripts to prepare your data and train a machine learning model. Then, in parts four and five, you'll run those Python scripts inside...
