Study Notes

Machine Learning

Machine learning is divided into four main types: Supervised Learning, Unsupervised Learning, Reinforcement Learning, and Cognitive Computing
Supervised Learning aims to train algorithms to describe input data and produce outputs effectively, and is used in applications like Risk Assessment, Fraud Detection, and Speech Recognition
Supervised Learning can be classified into two types of problems: Classification and Regression
Cognitive Computing enhances human-machine interaction to accomplish complex tasks and helps in problem-solving by recreating human thought processes in a computer model
