What is Machine Learning Algorithm?
A machine learning algorithm is a set of instructions or rules that enable a computer to learn patterns from data and make predictions or decisions without being explicitly programmed. These algorithms are designed to improve their performance over time by learning from data inputs.
Machine learning algorithms can be broadly categorized into three main types:
1. Supervised Learning: Algorithms learn from labeled training data to make predictions or decisions.
2. Unsupervised Learning: Algorithms learn patterns from unlabeled data to find hidden structures or insights.
3. Reinforcement Learning: Algorithms learn through trial and error interactions with an environment to maximize rewards.
