80/20 Study Guide - Key Concepts
What is Machine Learning?
Machine Learning is a subset of AI that enables systems to learn and improve from experience without being explicitly programmed.
The 20% You Need to Know:
- ML focuses on building algorithms that can learn patterns from data.
- It relies on training data to make predictions or decisions.
- ML models improve over time as they are exposed to more data.
Why It Matters:
Machine Learning powers many modern technologies, from recommendation systems to self-driving cars. Understanding ML is essential for leveraging AI in real-world applications.
Simple Takeaway:
ML is about teaching computers to learn from data and make decisions.
Supervised Learning
Supervised Learning is a type of ML where the model is trained on labeled data, meaning the input data is paired with the correct output.
The 20% You Need to Know:
- Used for tasks like classification and regression.
- Requires a labeled dataset for training.
- Examples include predicting house prices or classifying emails as spam.
Why It Matters:
Supervised Learning is widely used in industries like finance, healthcare, and marketing to make data-driven predictions.
Simple Takeaway:
Supervised Learning uses labeled data to teach models how to predict outcomes.
Unsupervised Learning
Unsupervised Learning is a type of ML where the model is trained on unlabeled data, identifying patterns and structures on its own.
The 20% You Need to Know:
- Used for clustering and dimensionality reduction.
- Does not require labeled data.
- Examples include customer segmentation and anomaly detection.
Why It Matters:
Unsupervised Learning helps uncover hidden patterns in data, making it valuable for exploratory analysis and decision-making.
Simple Takeaway:
Unsupervised Learning finds patterns in data without predefined labels.
Machine Learning: A Closer Look
Machine Learning is the process of training algorithms to learn from data and make predictions or decisions without explicit programming.
How It Works:
ML algorithms analyze data, identify patterns, and use those patterns to make predictions or decisions. The process involves data collection, model training, evaluation, and deployment.
Types of ML:
- Supervised Learning: Uses labeled data to train models.
- Unsupervised Learning: Finds patterns in unlabeled data.
- Reinforcement Learning: Trains models through trial and error using rewards and penalties.
Real-World Examples:
- Recommendation systems (e.g., Netflix, Spotify).
- Fraud detection in banking.
- Autonomous vehicles.
