What is noise in data and why does it matter?
Noise isn?t just random-it?s a challenge to overcome.
How It Works:
Noise refers to random or irrelevant variations in data-measurement errors, typos, or sensor glitches-that can mislead models if not handled.
Key Benefits of Managing Noise:
- Cleaner models: Reduces overfitting to spurious patterns.
- Better generalization: Focuses on true signal.
- Robustness: Improves performance on real-world data.
Real-World Use Cases:
- IoT sensors: Filter out transient spikes.
- Customer surveys: Correct typos and remove gibberish responses.
