By Abid Ali Awan, KDnuggets Assistant Editor on September 20, 2023 in Machine Learning. Image by Author.Semi-supervised learning is a machine learning method in which we have input data, and a fraction of input data is labeled as the output. It is a mix of supervised and unsupervised learning. Semi-supervised learning can be useful in cases where we have a small number of labeled data points to train the model.The Principal Component Analysis is a popular unsupervised learning technique for reducing the dimensionality of large data sets. It increases interpretability yet, at the same time, it minimizes information loss. It helps to find the most significant features in a dataset and makes the data easy for plotting in 2D and 3D.

The difference is that in supervised learning the “categories”, “classes” or “labels” are known. In unsupervised learning, they are not, and the learning process attempts to find appropriate “categories”. In both kinds of learning all parameters are considered to determine which are most appropriate to perform the classification.8 days ago ... 9 machine learning examples in the real world · 1.
