Machine Learning is a branch of Artificial Intelligence that uses algorithms to construct models to automate decision-making processes. It involves analysis of data to identify patterns and behavior that are too complex for humans to detect. Machine Learning algorithms can be used to predict, classify, cluster, and optimize data. Machine Learning is based on the idea of learning from past experiences. This means that machines can observe patterns in data and learn from it. By presenting data to the model, the model is able to learn how to analyze the data and make decisions. This process works by recognizing patterns in the data and using these patterns to make predictions. The most common type of Machine Learning is supervised learning. In supervised learning, the data is labeled and the machine is trained to recognize the labels. This type of Machine Learning can be used for classification, regression, and time series modeling. Unsupervised learning does not require labeled data. This type of Machine Learning uses algorithms to group the data together based on similarities. Unsupervised learning is often used for clustering, feature engineering, and anomaly detection. Finally, Reinforcement Learning uses a feedback loop to teach a model how to behave and make decisions.
