Random Seed
Domain: Data & Datasets
🎯 Motivation
A number that initializes random processes. Same seed = same random sequence = same results. Essential for reproducibility.
📋 Concrete Example
Seed = 42: model gets 85.2% accuracy. Seed = 123: model gets 84.8%. Same seed always gives the same result. Fix the seed for reproducibility.
🔗 Analogy
The starting position in a board game - same starting position = same game possibilities. A random seed sets the starting position for AI training.
