Q: What are the two basic categories of machine learning and how do they differ from each other?
A: Machine learning can be broadly categorized into supervised and unsupervised learning. In the case of supervised learning, the model is trained based on the historical data, which is treated as the version of truth, termed training data. In the case of unsupervised learning, the algorithm derives inferences based on the input data, without labeled training data. The hidden patterns within the datasets are derived on the fly.
