Understanding Batch Learning: Beginner Level
Simple Definition
Batch learning is like teaching a computer all at once using a big collection of examples, rather than teaching it one example at a time.
Real-World Analogy
Think of batch learning like studying for a final exam: instead of learning one topic each day (like online learning), you gather all your study materials and learn everything in one big study session.
Everyday Examples You've Experienced:
Photo apps that learn to recognize faces after you upload an entire album
Email spam filters that are updated monthly with new spam patterns
Movie recommendation systems that update their suggestions once a week
Fun Facts

Some batch learning systems can process millions of examples in a single training session
