Agenda
– Today, we will explore the basics of machine learning,
delve into some common algorithms, and look at realworld applications.
What is Machine Learning?
• Machine learning is a subfield of artificial
intelligence that provides systems the ability
to automatically learn and improve from
experience.
Types of Machine Learning
• Supervised Learning: Models are trained using
labeled data.
• Unsupervised Learning: Deals with unlabeled
data.
• Reinforcement Learning: Involves agents who
take actions to maximize rewards.
Supervised Learning
• Introduction
– Supervised learning is a type of machine learning
where models are trained on a labeled dataset.
• Components
– Features: Input data points.
– Labels: Output data points.
– Model: Algorithm that maps features to labels.
• Common Algorithms
– Linear Regression
Unsupervised Learning
• Introduction
– Unsupervised learning works with unlabeled data
and aims to identify patterns.
• Types
– Clustering
– Association
– Dimensionality Reduction
Reinforcement Learning
• Introduction
– Reinforcement learning involves an agent that
learns to make decisions to achieve a goal.
• Components
– Agent
– Environment
– Reward
